And here are the companies

 

Arctic Star Exploration TSXV:ADD

Promising geology and proven methodology will come together at Arctic Star Exploration’s (TSXV:ADD) Diagras project in the Northwest Territories’ diamondiferous Lac de Gras region. Currently holding 40% of a joint venture, the company intends to assume operation and increase its ownership when spring offers optimum work conditions.

In addition to drilling, Arctic Star’s plans include gravity and electromagnetic surveys on seven of the property’s 21 known kimberlites. The gravity/EM approach follows that of Kennady Diamonds, which successfully employed the methodology on its Kennady North project two kilometres away. In 2018 Kennady North was acquired by Mountain Province Diamonds TSX:MPVD, De Beers’ JV partner on the adjacent Gahcho Kué mine. Gravity and EM have so far found five drill targets at Diagras.

Arctic Star’s 100%-held Timantti diamond project in Finland hosts nine known diamondiferous kimberlites. With some 150 kilograms of samples ready for processing, ground work is expected to resume once pandemic conditions allow.

Ares Strategic Mining TSXV:ARS

Eight companies offer eight opportunities at one online event

Once re-opened, Lost Sheep will be
America’s only producing fluorspar mine.

The U.S. currently imports its entire supply of this critical mineral but Ares Strategic Mining TSXV:ARS plans to change that soon by opening the country’s only fluorspar operation. Production at Utah’s Lost Sheep mine could begin this autumn without de-risking through successive PEA and feasibility studies, but with the apparent confidence of the Mujim Group. The multinational fluorspar mining and distribution company visited the property earlier this year prior to buying a 9% stake in Ares.

Three of five exploration holes found visible fluorspar, while assays have just been released from 12 holes totalling 900 metres of delineation drilling. Results show high grades over wide intervals from near-surface and at-surface intercepts. Metallurgical tests have upgraded Lost Sheep material above 97% CaF2, achieving the level of higher-priced acidspar.

Ares also holds the Liard fluorspar project in northern British Columbia. Seven areas of the highway-accessible 476-hectare property host historic, non-43-101 estimates.

September 9 update: Ares launches this summer’s second drill program at Lost Sheep.

 

Commerce Resources TSXV:CCE

Eight companies offer eight opportunities at one online event

Well-understood host minerals, distribution of magnet
feed elements and a friendly jurisdiction distinguish
Commerce Resources’ RE-fluorspar project.

Few if any elements dominate concern about critical minerals like rare earths. That places all the more focus on Commerce Resources’ (TSXV:CCE) Ashram deposit, an advanced-stage Quebec project that also hosts one of the world’s largest fluorspar resources. While working towards pre-feasibility, the company has metallurgical studies advancing on a number of levels, benefiting not only Ashram but the creation of supply chains independent of China. The deposit’s carbonatite-hosted mineralization and relatively simple monazite, bastnasite and xenotime mineralogy complement conventional rare earths processing. Metallurgy has also upgraded Ashram’s fluorspar content to higher-priced acidspar.

Ashram also features a strong presence of high-demand magnet feed elements neodymium, praseodymium, dysprosium and terbium. Work is underway to upgrade the 2012 resource that used a 1.25% cutoff to show:

  • measured and indicated: 29.27 million tonnes averaging 1.9% total rare earth oxides and 2.94% fluorine

  • inferred: 219.8 million tonnes averaging 1.88% TREO and 2.21% F

The deposit starts at surface.

Looking at other critical minerals, Commerce also holds the advanced-stage Blue River tantalum-niobium deposit in southern British Columbia.

September 10 update: Saville Resources, Commerce Resources find more fluorspar in re-assayed core from Quebec niobium-tantalum project.

 

Core Assets Corp CSE:CC

Eight companies offer eight opportunities at one online event

Historic results, more recent sampling and a
greater understanding of regional geology prompted
Core Assets’ major land expansion in B.C.

Determined to become a major explorer in northwestern British Columbia’s Golden Triangle, Core Assets Corp CSE:CC started trading in July, then began September with a nine-fold property expansion. The inspiration for boosting its Blue and Silver Lime holdings to 14,815 hectares comes from continual advancements in the understanding of porphyry, skarn and carbonate replacement-type deposits globally and in the Triangle itself.

The new ground covers the Llewelyn fault zone, which the company believes to be the main transport corridor for high-grade metals found on the property at surface. An historic, non-43-101 drill hole at Blue reached 0.27% copper over 173.2 metres. Grab samples from 2018 graded up to 1.57 g/t gold, 46.5 g/t silver and 8.46% copper.

The 2018 grab samples from never-drilled Silver Lime included 1.16 g/t gold, 913 g/t silver, 12.45% zinc and 20% lead. Core’s regionally experienced team plans a regional magnetic survey over the property.

Watch an interview with the Core Assets team.

 

Dimension Five Technologies CSE:DFT

Creating high-value products, even energy, from waste materials is the goal of Aduro Energy, now subject of an LOI for a reverse takeover by Dimension Five Technologies CSE:DFT. Founded in 2012, Ontario-based Aduro has developed a smart chemistry approach using three water-based technologies to transform diverse feedstocks that include renewable oils as well as waste plastics, foams and rubber. The result can be new plastics, foams, hydrocarbon fuels or specialty chemicals.

Aduro has its three areas of technology—trademarked as Hydrochemolytic Plastics Upgrading, Hydrochemolytic Renewables Upgrading and Hydrochemolytic Bitumen Upgrading—now undergoing demonstration and commercialization stages.

Emerita Resources TSXV:EMO

Eight companies offer eight opportunities at one online event

Despite extensive previous mining, Aznalcollar
hosts an impressive historic base metals estimate.

Most of Spain’s bullion came from the New World but Emerita Resources TSXV:EMO believes there’s untapped gold-silver potential on its Paymogo polymetallic project. Located amid former and current operations in southern Spain’s Iberian Pyrite Belt, Paymogo’s Romanera deposit hosts an historic, non-43-101 estimate of 34 million tonnes averaging 0.42% copper, 2.2% lead, 2.3% zinc, 44.4 g/t silver and 0.8 g/t gold.

Eight kilometres away, Paymogo’s Infanta area has historic, non-43-101 reports of high-grade copper-lead-zinc-silver intervals. While preparing an exploration permit application, Emerita is compiling data from 51 holes at Romanera and 48 at Infanta for a digital database to guide another round of drilling.

The company also awaits a court decision regarding a disputed tender for the Aznalcollar zinc-lead past-producer on the same Iberian belt. In May Emerita signed a binding letter agreement to earn a 55% interest in the Sierra Alta gold property in northern Spain. Company assets also include a 50% JV interest in the Plaza Norte zinc project near Spain’s northern coast.

September 9 update: Emerita releases historic assays prior to drilling Paymogo.

 

Saville Resources TSXV:SRE

Eight companies offer eight opportunities at one online event

Saville outperformed historic intercepts with its
Phase I drill program on the Niobium Claim Group in Quebec.

Two kilometres from Commerce Resources’ Ashram RE-fluorspar deposit, another company explores for other critical minerals—niobium and tantalum. Working on a 75% earn-in from Commerce, Saville Resources TSXV:SRE has also found fluorspar potential on the early-stage Niobium Claim Group.

Saville sunk five holes last year in a promising Phase I campaign on the property’s Mallard prospect. Along with historic results, three drill programs total 14 holes and 3,537 metres on Mallard. Each program surpassed its predecessor for grades and widths while expanding three zones of mineralization that remain open in all directions. Encouraging historic drill results have also come from the project’s Northwest and Star Trench prospects. Yet to be drilled are other high-priority areas, especially Miranna where high-grade boulder samples have reached an exceptional 5.93% Nb2O5.

The property’s host rock predominates in pyrochlore-group minerals and/or ferrocolumbite, amenable to familiar processing methods as the world’s main source of niobium supply.

September 10 update: Saville Resources, Commerce Resources find more fluorspar in re-assayed core from Quebec niobium-tantalum project.

 

Zinc8 Energy Solutions CSE:ZAIR

Intermittent green electricity, grid backup and off-grid supply call for long-term electrical storage. Zinc8 Energy Solutions CSE:ZAIR has made inroads into New York by offering a low-cost, reliable approach.

The company’s system stores electricity in zinc particles, avoiding expensive battery minerals like lithium, vanadium and cobalt. When the storage system provides electricity, zinc particles combine with oxygen. When the system recharges, the zinc particles are regenerated and oxygen is returned.

Storage can be scaled from 20 kW to megawatts, making Zinc8’s system suitable for microgrids and utilities. The latter have already shown interest. 

In January the New York Power Authority, America’s largest public power organization, selected the Zinc8 system out of more than 60 contenders for a commercial or industrial demonstration facility. Two months later Digital Energy Corp chose Zinc8 to install a 100 kW/1.5 MWh storage system at a combined heat and power (CHP) plant in Brooklyn. Buoyed by New York interest, Zinc8 has since created a U.S. subsidiary.

Update: Gaia Metals expands Idaho gold project, awaits field program results prior to autumn drilling

September 2nd, 2020

Update: On September 2 Gaia Metals TSXV:GMC announced the expansion of its Freeman Creek property by 263 hectares, for a total of approximately 862 hectares. The newly staked claims cover potentially mineralized extensions to the Carmen Creek prospect and an area adjacent to the Gold Dyke prospect. Both of the new areas were identified during the recent field campaign.

 

by Greg Klein | August 31, 2020

A 14-day campaign of rock and soil sampling, along with a magnetic survey, has wrapped up on the newly acquired Freeman Creek gold project in Idaho. While waiting for data, Gaia Metals TSXV:GMC has permitting underway for anticipated fall drilling.

A malachite-magnetite-sulphide sample
from the property’s Carmen Creek prospect.

Focus of the work was the 599-hecatre property’s Gold Dyke and Carmen Creek prospects, about three kilometres apart. Historic, non-43-101 results from Gold Dyke include a 1980s drill intercept of 1.5 g/t gold and 12.1 g/t silver over 44.2 metres. Among historic, non-43-101 Carmen Creek results was an outcrop sample grading 14.15 g/t gold, 63 g/t silver and 1.2% copper.

The summer program saw 222 rock samples collected throughout the property, a magnetic survey over both prospects and a 162-sample soil grid on Gold Dyke. Prospecting at Carmen Creek outlined a mineralized zone of one to two metres and veining extending five to 10 metres into the wall rock, Gaia stated. Preliminary interpretation of Carmen Creek geophysical data shows a magnetic high coinciding with the mineralization and likely reflecting the magnetite content, the company added.

The crew also verified locations of historic drill collars, adits and open pits.

“Our Phase I surface program at Freeman Creek appears to have been a resounding success, with sample mineralogy indicating we have found what we are looking for,” said president/CEO Adrian Lamoureux. “We are eagerly anticipating assay results as we advance with the Phase II drill program planned for this fall.”

Apart from the Freeman Creek flagship, Gaia’s assets include the Corvette-FCI project in Quebec’s James Bay region, location of impressive copper-gold-silver and lithium-tantalum assays. Further potential for drilling has been identified through a new interpretation of geophysical resultsGaia holds 100% of the property’s Corvette claims and a 75% earn-in from Osisko Mining TSX:OSK spinout O3 Mining TSXV:OIII on the FCI-East and FCI-West claims.

Gaia’s portfolio also includes the Pontax lithium-gold property in Quebec, the Golden silica property in British Columbia and a 40% stake in the Northwest Territories’ Hidden Lake lithium property.

Last week the company closed a private placement of $360,000 that followed a July placement of $603,000.

Gaia Metals’ Idaho field program anticipates fall gold-silver-copper drilling

August 12th, 2020

by Greg Klein | August 12, 2020

Just weeks after signing a definitive agreement to acquire the property, this company has a crew en route for Phase I field work. Gaia Metals TSXV:GMC plans to begin verification of historic results on its Freeman Creek gold-silver-copper project prior to a drill program expected in autumn.

The team will verify locations of historic collars, adits and open pits, conduct property-wide prospecting, sampling and magnetic surveying, and carry out soil sampling on a grid across the project’s Gold Dyke prospect. The latter is one of two areas of particular interest on the 599-hectare road-accessible property, along with the Carmen Creek prospect.

Gaia Metals’ Idaho field program anticipates fall gold-silver-copper drilling

Previous work at Gold Dyke traced mineralization for 457 metres along strike and 183 metres at depth. Historic, non-43-101 trench results included:

  • 6.86 g/t gold and 199 g/t silver over 7 metres

  • 5.49 g/t gold and 130 g/t silver over 5.8 metres

  • 19.9 g/t gold, 65 g/t silver and 1.05% copper over 3.7 metres

One grab sample graded 60 g/t gold and 1,440 g/t silver.

An historic, non-43-101 drill result from the 1970s showed:

  • 0.46 g/t gold, 7.1 g/t silver and 0.1% copper over 13.7 metres

Two 1980s holes brought further historic, non-43-101 assays:

  • 1.5 g/t gold and 12.1 g/t silver over 44.2 metres

  • 1.7 g/t gold and 17.1 g/t silver over 21.3 metres

About three kilometres away, Carmen Creek underwent sampling from outcrop and former workings, producing these historic, non-43-101 assays:

  • 14.15 g/t gold, 63 g/t silver and 1.2% copper

  • 1.8 g/t gold, 43 g/t silver and 1% copper

Freeman Creek sits entirely on U.S. Bureau of Land Management turf, allowing a relatively smooth process for the drill permitting already underway. Idaho ranks #8 on the most important index of the Fraser Institute Survey of Mining Companies.

“Verification and expanding upon the historical results are the first steps toward unlocking the potential of this asset for our shareholders,” noted president/CEO Adrian Lamoureux. “With gold achieving historic highs, our timing couldn’t be better.”

Gaia’s portfolio also includes the Corvette-FCI property in Quebec’s James Bay region, where the company has found impressive copper-gold-silver and lithium-tantalum grades. A new interpretation of geophysical data shows additional drilling potential. Gaia holds 100% of the project’s Corvette claims and a 75% earn-in from Osisko Mining TSX:OSK spinout O3 Mining TSXV:OIII on the FCI-East and FCI-West claims.

Gaia’s other assets include the Pontax lithium-gold property in Quebec, the Golden silica property in British Columbia and a 40% stake in the Northwest Territories’ Hidden Lake lithium property.

Last month the company closed an over-subscribed private placement of $603,000.

Arctic Star Exploration to resume work and increase stake in NWT diamond project

July 27th, 2020

by Greg Klein | July 27, 2020

The idled but promising Diagras project should see new activity as one joint venture partner takes over operations from the other. New manager Arctic Star Exploration TSXV:ADD, which holds the minority portion of the 60/40 JV, announced a proposed $1.6-million budget over the next 12 months to drill the Diagras property next spring. JV partner Margaret Lake Diamonds TSXV:DIA “has elected not to participate in this program and, in doing so, will dilute once the program completes and expenditures are met,” Arctic Star stated.

Arctic Star Exploration plans to resume work, increase stake in NWT diamond project

Hosting 21 kimberlites discovered by De Beers, Diagras sits within the Northwest Territories’ Lac de Gras diamond field that’s home to the recently suspended Ekati mine and the Rio Tinto NYSE:RIO/Dominion Diamond Mines Diavik operation.

Spring offers optimum work conditions in the region, when winter roads and rig-friendly frozen lakes coincide with over 12 hours of daily light. Arctic Star’s agenda also calls for geophysics on seven kimberlites that have yet to undergo gravity and electromagnetic surveys. Permitting is already underway.

Arctic Star’s approach borrows from the success of Kennady Diamonds on its Kennady North project, two kilometres southeast of Diagras. While previous Lac de Gras explorers relied heavily on magnetics, that approach might find only a portion of a larger kimberlite complex that contains other geophysical features. Kennady’s gravity and EM surveys showed the Kelvin and Faraday kimberlites to be “complexes with previously unknown kimberlite phases that were highly diamondiferous,” Arctic Star explained.

In 2018 Kennady and its project were taken over by Mountain Province Diamonds TSX:MPVD, which JVs with De Beers on the adjacent Gahcho Kué operation.

Gravity and EM surveys employed so far at Diagras have found at least five targets that warrant drilling, according to Arctic Star. Examples include the Black Spruce kimberlite, with distinct gravity and EM anomalies, and the HL01 kimberlite, where “previous workers may have thought an EM anomaly was explained by the magnetic kimberlite targeted and drill-tested. However our ground EM survey shows a distinct EM anomaly to be separate to the magnetic anomaly, and it deserves a dedicated drill test.”

Surveys also reveal drill targets at the property’s Jack Pine, Suzanne, Kong and Penelope kimberlites.

In Finland, however, Arctic Star has suspended field work on its 100%-held Timantti diamond project due to pandemic-related travel restrictions. Plans remain to process 150 kilograms of samples from the two most recently discovered of the property’s nine known diamondiferous kimberlites. The company intends to resume ground work when travel becomes viable.

In February Arctic Star closed a private placement totalling $868,400.

Update: Gaia Metals signs definitive agreement, plans immediate exploration on Idaho gold-silver project with historic high grades

July 27th, 2020

Update: On July 27, 2020, Gaia Metals announced a definitive agreement to acquire Freeman Creek on the LOI terms reported below. Immediate plans include prospecting, mapping and sampling of historic occurrences, and potential soil sampling and ground geophysics. A possible Phase II program would drill the property to verify and expand on previous results.

On July 17 the company closed an over-subscribed private placement of $603,000.

 

by Greg Klein | June 4, 2020

Impressive earlier work in one of the world’s top-ranked mining jurisdictions has brought new attention to a neglected property. Under terms of a non-binding letter of intent Gaia Metals TSXV:GMC would pick up Freeman Creek, a 599-hectare site of previous trenching, drilling and mining. Two targets about three kilometres apart have the company especially encouraged.

Mineralization at the Gold Dyke prospect has been traced for 457 metres along strike and 183 metres at depth. Trench samples as far back as 1910 brought obviously non-43-101 results as high as:

Gaia Metals signs LOI for Idaho gold-silver project with historic high grades

  • 6.86 g/t gold and 199 g/t silver over 7 metres

  • 5.49 g/t gold and 130 g/t silver over 5.8 metres

  • 19.9 g/t gold, 65 g/t silver and 1.05% copper over 3.7 metres

One grab sample reached 60 g/t gold and 1,440 g/t silver.

An historic 1970s-era drill intercept brought:

  • 0.46 g/t gold, 7.1 g/t silver and 0.1% copper over 13.7 metres

More non-43-101 assays, from two 1980s holes, showed:

  • 1.5 g/t gold and 12.1 g/t silver over 44.2 metres

  • 1.7 g/t gold and 17.1 g/t silver over 21.3 metres

Although records haven’t been found, Cominco and BHP explored Gold Dyke for large-scale copper potential during the 1990s.

The historic Carmen Creek mine prospect has delivered samples from outcrop and former workings with these non-43-101 results:

  • 14.15 g/t gold, 63 g/t silver and 1.2% copper

  • 1.8 g/t gold, 43 g/t silver and 1% copper

The historic work at Freeman Creek appears to have only scratched the surface of this project’s potential. Coupled with a relatively simple and straightforward permitting process, we are excited to aggressively pursue this opportunity.—Adrian Lamoureux,
Gaia Metals president/CEO

Located about 15 kilometres from the town of Salmon, Freeman Creek can be reached by highway, gravel roads and trails. Last year Idaho ranked #8, up from 16th the previous year, on the most important index of the Fraser Institute Survey of Mining Companies.

A 100% interest would cost Gaia a total of $90,000, four million shares and two million warrants within a year of TSXV approval. The company would pay an additional $1 million in cash or shares on defining a gold-equivalent resource exceeding a million ounces. The vendor would retain a 2.5% NSR, half of which Gaia could buy for $1.5 million.

In Quebec’s James Bay region, Gaia’s Corvette-FCI property has yielded high-grade gold, copper-gold-silver and lithium-tantalum grades. Announced last April, a new interpretation of geophysical data found additional drilling potential. Gaia holds 100% of the project’s Corvette claims and a 75% earn-in from Osisko Mining TSX:OSK spinout O3 Mining TSXV:OIII on the FCI-East and FCI-West blocks.

Among other assets, Gaia’s portfolio includes the Pontax lithium-gold property in Quebec, the Golden silica property in British Columbia and a 40% stake in the Northwest Territories’ Hidden Lake lithium property.

Canadian and Australian rocks offer clues about the origin of life

by Joshua Davies, Professor, Sciences de la Terre et de l’atmosphère, Université du Québec à Montréal and Jesse Reimink, Assistant Professor, Geosciences, Pennsylvania State University | posted with permission of The Conversation | June 17, 2020

The rocks at the surface of modern Earth are broadly divided into two types: felsic and mafic. In general felsic rocks are relatively low in density—for a rock—and light in colour because they are made from whitish minerals rich in silicon and aluminium. Half Dome in California is made of granite, a felsic rock. Mafic rocks, in contrast, are relatively high in density and dark in colour because they contain minerals rich in iron and magnesium. Giant’s Causeway in Northern Ireland is made of basalt, a mafic rock.

Canadian and Australian rocks offer clues about the origin of life

an unusual formation comprising mafic rocks.

The difference in density between felsic and mafic rocks means that felsic rocks are more buoyant and therefore sit at higher elevations above the earth’s mantle (the layer inside the earth between the crust and the core). For this reason, felsic rocks make up Earth’s continents whereas the lower-elevation crust under the oceans is mafic.

The mechanisms that separated the rocks at Earth’s surface into these two groups may have also created the environment needed for life to flourish 4.3 million years ago, very early in the history of Earth.

The separation into these two rock types is the result of plate tectonics: where the tectonic plates separate and move apart, the rocks below become depressurized, melt and fill in the gap between them, like the Mid-Atlantic Ridge. The rock that fills the gap between the plates is mafic.

When one plate slides below another, fluids released from the lower plate cause melting in the mantle. These melts have to pass through the upper plate to reach the surface. On their way to the surface, they undergo a series of processes called fractional crystalization, which can change mafic melts into felsic melts.

Establishing timelines

When this separation happened is a matter of great debate in earth sciences because it may allow us to determine when Earth became habitable for life. Many earth scientists believe that the weathering of continental crust may have provided the nutrients for life to thrive. Identifying when the first continents formed indicates when this may have occurred.

Earth scientists also debate whether plate tectonic processes in the past were the same as those occurring today, and whether they were even needed to form continental crust in the past. The first continental crust may have been formed through the interaction of oceanic crust and mantle plumes of heat coming from the earth’s core. Another theory suggests that continental crust formed through meteorite bombardment.

The exact mechanism is important for understanding the history and evolution of Earth, and may help understand the processes that could be occurring on other planets.

Reviewing the records

Our recent study looked at the oldest geological material on Earth. The results suggest that Earth was already separating into these two rock types by 4.3 billion years ago—effectively since the beginning of Earth’s geological record. Our data also gave intriguing insights into the tectonic processes that may have been occurring at that time.

The origin of continental crust is debated in part because the further back in time you go, the fewer rocks there are to study. Samples from the Acasta Gneiss Complex in the Northwest Territories were found to be about four billion years old—the oldest known rocks on Earth. These Acasta Gneiss rocks are felsic and composed of tonalite-trondhjemite-granodiorite.

There are very few older samples from Earth, the most famous of which is the Jack Hills zircons. These are up to 4.3 billion years old, 300 million years older than the Acasta Gneiss. They are tiny grains of mineral zircon that have been eroded out of their parental rock (the rock in which they initially crystallized).

These zircons are found in much younger sediments in Australia, which means that it’s difficult to determine what kind of rocks these minerals originally came from, leaving open the question of whether there was continental crust during the earliest period of Earth’s history.

Continental connections

In our recent study, we compared all aspects of the chemistry of the zircon crystals from Acasta rocks to the Jack Hills zircons to see if they could have been formed in a similar environment.

We found that the two sets of zircon grains are chemically identical, suggesting that they formed from the same kinds of rocks and likely in the same kinds of tectonic settings. This means that the earth may have started to create continental-type crust very soon after it formed.

The chemical composition of both suites of zircon crystals also suggests that they grew in magmas that originated at great depth in the earth. Deep origins for magmas are a typical sign of subduction on the modern earth.

We compared the amount of uranium in the crystals to the amount of ytterbium, a rare element. When a magma forms at great depth, the mineral garnet is often present, which gathers ytterbium. This means less ytterbium is taken up by zircon crystals, suggesting that a relative lack of ytterbium indicates that these magmas formed in deep environments.

The Jack Hills zircons are known to have crystallized at relatively low temperatures. We found that the temperatures from Acasta zircons matched exactly with the Jack Hills zircons, further indicating their similarity.

Finding the beginning

Ultimately, our results indicate that the tectonic processes occurring at the beginning of the geological record may not have been so different from the processes occurring afterwards. Evidence that things were not much different from modern Earth brings intriguing insights into the potential for the origin of life and the habitability of early Earth, possibly confirming that life was present very early in Earth’s history.

Legendary mine finder David Lowell dead at 92

May 6th, 2020

An axe injury while staking claims in central Saskatchewan helps illustrate the working life of an intrepid geologist in the 1950s. While topping trees David Lowell slashed his hand, but heavy blood loss hardly justified helicopter transport for medical attention. A few days later, as bleeding continued despite application of a rag bandage, a fellow geologist sewed up the cut with black carpet thread.

Although Lowell admitted the process had him howling with pain, he concluded with stoic simplicity: “This worked fine.” They stayed in the bush for another week before heading back to Lac La Ronge, where a couple of Cree nurses examined the amateur stitch-up with amusement.

Lowell also spent time in Manitoba and the Northwest Territories as well as in British Columbia, where he worked at Highland Valley, Endako, Gibraltar and Craigmont. But the legend who passed away earlier this week was best known for discoveries farther south, starting in his native Arizona. The grandson of an Ontario-born prospector is credited with 17 major discoveries over 50 years in Arizona, Argentina, the Philippines, B.C., Chile, Peru, Ecuador and Paraguay.

Intrepid Explorer: The Autobiography of the World’s Best Mine Finder attributes significant work from others for seven of those achievements, which he categorizes as “maybe-I-was-responsible-for orebodies.” As he added, “there always are many more discoverers than discoveries.”

Lowell’s boots hit ground over much of the world but he also delivered university lectures in several countries and published widely. A longstanding collaboration with John Guilbert brought fame for the duo, better understanding of geology and many new mines through the Lowell-Guilbert Porphyry Copper Model, first published in 1970.

The model led to Lowell’s first discoveries, Kalamazoo and Vekol in Arizona, “which were remarkable at the time given the lack of visible copper mineralization at surface,” said a May 5 statement from Solaris Resources. Those finds were followed by Bajo Alumbrera in Argentina, to which Lowell acknowledged the contribution of others.

“David went on to discover the world’s largest copper deposit, La Escondida, in Chile in 1981,” Solaris pointed out. “This came from recognizing how the signature of his porphyry copper model would be modified in an extremely arid environment by a process known as ‘super leaching,’ which five prior companies exploring the property previously had failed to recognize.

“Likewise, in Peru, David identified the Northern Peru Gold Belt after library study, regional mapping, reconnaissance and sampling in a region that was not thought to be prospective. This work allowed him to narrow his focus and make the Pierina gold discovery in 1996, which was acquired by Barrick Gold for over $1 billion later that year.

“With Peru Copper, David took what was a known but under-appreciated deposit in Toromocho, relogged the existing drill core and completely reinterpreted the geology to lay the foundation for an exploration program that would increase its size by more than an order of magnitude. The project was acquired in 2007 for over $800 million.”

His last discoveries included Mirador in Ecuador, which began operation last year under a Chinese consortium, and Solaris’ flagship project Warintza in Ecuador, along with Lowell’s participation in finding Alto Parana in Paraguay. Lowell remained a Solaris consultant and strategic partner until his passing.

“Up until the very end of his life, David was busy designing programs to test his vision for the future of discovery in the Americas,” the company stated. “Innovation and ingenuity were constants throughout his legendary career.”
