Geoscience BC maps Greenwood’s mineral potential

September 28th, 2018

by Greg Klein | September 28, 2018

An historic British Columbia mining camp comes under additional scrutiny with new research released September 28. Geoscience BC’s latest report and 1:50,000-scale map focus on the province’s south-central Greenwood district, about 500 kilometres east of Vancouver.

Mining on the 800-square-kilometre area dates back to the late 1880s. Some 26 past-producers have given up more than 1.2 million ounces of gold and over 270,000 tonnes of copper, along with silver, lead and zinc, according to the independent non-profit organization. With a number of juniors currently working to find more mineralization, this research “should bolster the recent revival of mineral exploration activity in the Greenwood area,” said Geoscience BC VP of minerals and mining Bruce Madu.

Among the active companies is Grizzly Discoveries TSXV:GZD, which holds about 72,840 hectares of Greenwood turf. Under a 75% earn-in, Kinross Gold TSX:K has been drilling for gold in the Midway area of Grizzly’s holdings. Grizzly has been conducting geophysics and surface exploration on its Robocop cobalt-copper-silver claims and plans drilling for three other Greenwood targets.

Just across the international border, Kinross operated the Kettle River-Buckhorn gold mine until last year, extracting 1.3 million ounces over nine years.

Another of Greenwood’s large landholders is Golden Dawn Minerals TSXV:GOM, which attributes 31 historic mines to its 15,400-hectare portfolio.

The Greenwood report might help illuminate other parts of B.C. as well. “This area could hold the key to a better understanding of mineral deposits that formed during key geological events that span almost 200 million years,” Madu added.

Working with First Nations, local communities, governments, academia and the resource sector, Geoscience BC opens its research to the public “with the aim of encouraging exploration, economic activity and informed land use decisions.” Most funding comes from the provincial government.

Visual Capitalist: Nine reasons mining investors are looking at Yukon companies

September 18th, 2018

by Jeff Desjardins | posted with permission of Visual Capitalist | September 18, 2018

In the mining industry, location is paramount.

Invest your capital in a jurisdiction that doesn’t respect that investment, or in a place with little geological potential, and it’s possible that it will end up going to waste.

That’s why, when there’s a place on the map that has world-class geology and also a plan for working with miners and new explorers, the money begins to flow to take advantage of that potential.

Why investors are looking at the Yukon

This infographic comes to us from the Yukon Mining Alliance and it shows nine reasons why people are investing in Yukon mining and exploration companies today.

 

Nine reasons mining investors are looking at Yukon companies

 

For resource investors, it is rare to see variables like government investment, jurisdiction, geological potential and investment from major mining companies all aligning.

However, in the Yukon, it seems this may be the case. Here are nine reasons the Yukon is starting to attract more investment capital:

1. Rich history
Mining was central to the Yukon even over a century ago, when over 100,000 fortune-seekers stampeded into the Yukon with the goal of striking it rich in the famous Klondike Gold Rush.

2. Geological profile
In the last decade, there have been major discoveries of gold, silver, copper, zinc and lead in the Yukon—but perhaps most interestingly, only 12% of the Yukon has been staked, making the region highly under-explored. Spending on exploration and development rose from $93 million to $158 million from 2015 to 2017.

3. Major investment
Major mining companies now have a stake in the polymetallic rush. Recent companies to foray into the Yukon include Agnico Eagle Mines TSX:AEM, Barrick Gold TSX:ABX, Coeur Mining NYSE:CDE, Goldcorp TSX:G, Kinross Gold TSX:K and Newmont Mining NYSE:NEM.

4. Leaders in exploration and mining
Juniors in the region are working on new geological ideas as well as new technology to unlock the vast potential of the region.

5. Progressive partnerships
First Nations and the government of Yukon have recently championed a new government-to-government relationship that enables them to be on the exact same page when it comes to mineral projects.

6. Government investment
The Yukon government is investing in new infrastructure via the Resource Gateway project. It also offers the Yukon Mineral Exploration Program, which provides a portion of risk capital to explore and develop mineral projects to an advanced stage.

7. Made in Yukon process
The Yukon government also tries to foster regulatory certainty to create clarity for companies and investors through its customized tri-party process.

8. Infrastructure
The jurisdiction has 5,000 kilometres of government-maintained roads, receives 95% of power from clean hydro, has international and local airports, and has access to three deep-water, ice-free ports.

9. Geopolitical stability
Canada offers geopolitical stability to start with—but with unprecedented cooperation between the territorial government and First Nations, the Yukon is arguably a step above the rest of the country.

Emerita Resources expands portfolio with Brazilian lithium acquisition

September 12th, 2018

by Greg Klein | September 12, 2018

A company focused on base metals in two continents has broadened its approach by moving into a lithium-producing neighbourhood. By exercising its 100% option, Emerita Resources TSXV:EMO picks up the Falcon Litio MG project, half a kilometre from the Companhia Brasileira de Litio lithium deposit currently being mined. Initial field work on Falcon has found pegmatite dykes similar to mineralized dykes on CBL’s property.

Emerita Resources expands portfolio with Brazilian lithium acquisition

Located in eastern Brazil’s Minas Gerais state, the region is hardly new to Emerita. The state also hosts the company’s 75%-held Salobro zinc project, where drilling wrapped up in July with an initial release of high-grade assays. Vale NYSE:VALE had previously attributed the property with an historic, non-43-101 estimate of 8.3 million tonnes averaging 7.12% zinc-equivalent for 1.3 million zinc-equivalent pounds, using a 3.5% zinc-lead cutoff. Emerita has a 43-101 resource due imminently.

But location was just part of the reason Emerita considered Falcon to be “an exceptional opportunity to add value at a low cost,” said CEO David Gower. “There has been interest expressed by third parties in potentially getting involved in the Litio project.”

Emerita gets Falcon on issuing a third tranche of 500,000 shares. The vendor retains a 2% NSR. Should the project achieve a resource showing at least 20 million tonnes averaging 1.3% Li2O, with at least half in the indicated or measured categories, Emerita pays the vendor $5 million cash or issues an equal amount in shares.

Besides the two Brazilian projects, the company holds three properties in Spain: Plaza Norte, a 50/50 joint venture on a zinc-lead past-producer; Aznalcollar, with an historic, non-43-101 zinc-lead-copper estimate; and Paymogo, with two historic, non-43-101 zinc-lead estimates.

In July Emerita offered a private placement of up to $3 million.

Saville Resources discovers new zinc-silver-nickel zone at surface in Quebec

August 8th, 2018

by Greg Klein | August 8, 2018

A property with limited exploration but encouraging geophysics shows further promise following a recent field program. Of eight surface samples collected by Saville Resources TSXV:SRE on its 3,370-hectare Covette project in Quebec’s James Bay region, one returned 1.2% zinc and 68.7 g/t silver, while three others assayed between 0.13% and 0.19% nickel.

Saville Resources now plans trenching and channel
sampling to follow Covette’s grab sample assays.

Sampling took place along a visible strike of about 200 metres directly above an area of high conductivity found by a 2016 VTEM program that spotted several EM conductors coinciding with strong magnetic anomalies.

Underlying the region is a greenstone belt “comprised of various mafic to ultramafic rock units considered prospective for base and precious metals (nickel-copper-cobalt-platinum group elements-gold-silver), as well as pegmatite-hosted rare metals (lithium-tantalum),” Saville reported. “Komatiites have also been described in the region with such rock types known to host significant nickel-copper massive sulphide deposits at other localities globally, adding further to the prospective nature of the region.”

A sampling program in 2017 brought 0.18% nickel, 0.09% copper and 87 ppm cobalt. One historic, non-43-101 grab sample returned 4.7% molybdenum, 0.73% bismuth, 0.09% lead and 6 g/t silver. Another historic sample showed 1.2 g/t silver and 0.18% copper.

Further plans include follow-up trenching and channel sampling. Saville filed a 43-101 technical report on the property and closed its 100% acquisition in June.

Covette sits about 190 kilometres east of the town of Radisson and 10 kilometres north of the all-weather Trans-Taiga road and the adjacent hydro-electricity transmission line.

In another northern Quebec project, Saville has a 43-101 technical report underway for the Miranna claims situated on the Eldor property that hosts Commerce Resources’ (TSXV:CCE) advanced-stage Ashram rare earths deposit. Saville would acquire a 75% earn-in subject to exchange approval. In April the companies released niobium-tantalum boulder sample grades as high as 4.3% Nb2O5 and 700 ppm Ta2O5.

Last month Saville offered two private placements totalling up to $2 million.

Emerita Resources finishes drilling, plans Brazil zinc resource estimate in two weeks

July 26th, 2018

by Greg Klein | July 26, 2018

With its initial drill program wrapped up on time and on budget, Emerita Resources TSXV:EMO expects to release a resource estimate for its Salobro zinc project in eastern Brazil within two weeks. The campaign totalled 22 holes for 3,676 metres. Thirteen holes were intended to expand the historic resource and four others twinned historic holes, while five large-diameter holes collected material for metallurgical tests.

Some standout assays from the batch released July 26 include:

Emerita Resources’ drill program expanded Salobro’s
mineralization without exceeding the previous depth.

Hole 012

  • 11.19% zinc and 1.26% lead over 2.8 metres, starting at 111.65 metres in downhole depth

Hole 013

  • 11.62% zinc and 0.4% lead over 1.71 metres, starting at 102.97 metres

Hole 016

  • 3.65% zinc and 0.2% lead over 8.46 metres, starting at 119 metres

  • 7.71% zinc and 0.99% lead over 3.43 metres, starting at 141.1 metres

The company interprets widths to be close to true widths.

The overall program succeeded in expanding mineralization up dip and along strike, with the historic deposit remaining open at depth, Emerita stated. The results also improve continuity, while geophysical analysis shows potential mineralization plunging to the west.

An historic, non-43-101 estimate compiled by Vale NYSE:VALE calculated 8.3 million tonnes averaging 7.12% zinc-equivalent at a cutoff of 3.5% zinc-lead.

Adding mineralization that does not require increasing depth should have a positive impact on the PEA results.—David Gower,
chairperson and incoming CEO
of Emerita Resources

“We have increased the limits of the near-surface mineralization, which was a key objective of the program,” pointed out chairperson David Gower. “The NI 43-101 mineral resource estimate that is being prepared will be the basis for the planned preliminary economic assessment and adding mineralization that does not require increasing depth should have a positive impact on the PEA results.”

Effective August 1, Gower and current CEO Michael Timmins swap positions, with Gower becoming CEO and Timmins chairing the board.

Also emphasizing the shallow mineralization, project manager Carlos Cravo added: “The relogging of the historical drilling combined with the new data has resulted in an improved understanding of the deposit morphology that will improve drill targeting and should benefit any future mine plan should the deposit be put into production.”

Emerita holds a 75% share of the 1,210-hectare property, with the remainder held by IMS Engenharia Mineral Ltda. Regional infrastructure includes paved roads, rail, power and water.

In northern Spain’s Reocin mining district, Emerita takes part in a 50/50 joint venture on the Plaza Norte zinc-lead project. The JV has drill permitting underway to update historic work.

Emerita also announced a private placement offered up to $3 million, with proceeds intended for Salobro. The company closed an oversubscribed private placement of $4.24 million last December.

Infographic: A new bull market in base metals?

July 11th, 2018

by Nicholas LePan | posted with permission of Visual Capitalist | July 11, 2018

Base metals are the most fundamental minerals produced for the modern economy and metals such as copper, zinc, nickel, lead and aluminum are the key components that support sustained economic growth.

During periods of economic expansion, these are the first materials to support a bustling economy, reducing inventory at metal warehouses and eventually their source, mines.

A base metals boom?

This infographic comes to us from Tartisan Nickel CSE:TN and it takes a look at the surging demand for base metals for use in renewable energy and EVs, and whether this could translate into a sustained bull market for base metals.

The base metals boom: Start of a new bull market?

 

Over the last three years, prices of base metals have risen on the back of a growing economy and the anticipation of usage in new technologies such as lithium-ion batteries, green energy and electric vehicles:

Cobalt: +232%
Zinc: +64%
Nickel: +59%
Copper: +45%
Lead: +34%
Tin: +36%
Aluminum: +42%

As goes the success and development of nations, so goes the production and consumption of base metals.

Why higher prices?

Development outside of the Western world has been the main driver of the base metals boom and it will likely continue to push prices higher in the future.

China has been the primary consumer of metals due to the country’s rapid economic expansion—and with recent efforts to improve environmental standards, the country is simultaneously eliminating supplies of low-quality and environmentally toxic metal production. India and Africa will also be emerging sources of base metal demand for the coming decades.

But this is not solely a story of developing nations, as there are some key developments that will include the developed world in the next wave of demand for base metals.

New sources of demand

Future demand for base metals will be driven by the onset of a more connected and sustainable world through the adoption of electronic devices and vehicles. This will require a turnover of established infrastructure and the obsolescence of traditional sources of energy, placing pressure on current sources of base metals.

The transformation will be global and will test the limits of current mineral supply.

Renewable energy technology

The power grids around the world will adapt to include renewable sources such as wind, solar and other technologies. According to the World Energy Outlook (IEA 2017), it is expected that between 2017 and 2040, a total of 160 GW of global power net additions will come from renewables each year.

Renewables will capture two-thirds of global investment in power plants to 2040 as they become, for many countries, the cheapest source of new power generation. Renewables rely heavily on base metals for their construction and would not exist without them.

Electric vehicles

Gasoline cars will be fossils. According to the International Energy Agency, the number of electric vehicles on the road around the world will hit 125 million by 2030. By this time, China will account for 39% of the global EV market.

Dwindling supply

Currently, warehouse levels in the London Metals Exchange are sitting at five-year lows, with tin leading the pack with a decline of 400%.

According to the Commodity Markets Outlook (World Bank, April 2018), supply could be curtailed by slower ramp-up of new capacity, tighter environmental constraints, sanctions against commodity producers and rising costs. If new supply does not come into the market, this could also drive prices for base metals higher.

New supply?

There is only one source to replenish supply and fulfill future demand, and that is with mining.

New mines need to be discovered, developed and come online to meet demand. In the meantime, those that invest in base metals could see scarcity drive prices up as the economy moves towards its electric future on a more populated planet.

An extended base metals boom may very well be on the horizon.

Saville Resources closes Quebec nickel-copper-cobalt acquisition, files 43-101, readies summer program

June 26th, 2018

by Greg Klein | June 26, 2018

An undrilled property with encouraging geophysical results will undergo a summer field program, now that Saville Resources TSXV:SRE has finalized its acquisition of the James Bay-region Covette project. A 1,402-line VTEM survey from 2016 outlined at least six areas of high conductivity on the 3,315-hectare property, with one zone extending southeast about 4.5 kilometres and another trending northeast. Those areas “need to be evaluated,” stated a 43-101 technical report filed this month.

project, which now has Phase I field work planned.

Sampling conducted last year showed 0.18% nickel, 0.09% copper and 87 ppm cobalt, but the field program wasn’t sufficient to explain the source of the VTEM anomalies, which may indicate a source at depth, the company stated.

An historic, non-43-101 sample assayed 4.7% molybdenum, 0.73% bismuth, 0.09% lead and 6 g/t silver. Another brought 1.2 g/t silver and 0.18% copper.

A Phase I field program recommended by the technical report would include detailed mapping and sampling in areas of high-conductivity, channel sampling and further geophysics. The project sits about 10 kilometres north of the all-weather Trans-Taiga road and adjacent transmission line.

Meanwhile work continues on another Quebec acquisition as Saville prepares a 43-101 technical report on the Miranna claims, located on the Eldor property that hosts Commerce Resources’ (TSXV:CCE) advanced-stage rare earths deposit. In April the companies reported assays as high as 4.3% Nb2O5 and 700 ppm Ta2O5, results in line with previous high grades. Subject to exchange approval, Saville would acquire a 75% earn-in on Miranna.

Pistol Bay Mining releases zinc-copper assays from Ontario, prepares for new drilling

June 13th, 2018

by Greg Klein | June 13, 2018

As a long-overdue modern exploration program continues on northwestern Ontario’s Confederation Lake, Pistol Bay Mining TSXV:PST released assays for an initial three-hole 1,555-metre program on the property’s Arrow zone. The results “confirm the consistent nature of mineralization in the Arrow zone and give us more confidence in the existing mineral resource estimate,” noted president/CEO Charles Desjardins. The assays show:

Hole GL18-01

  • 0.73% copper, 2.22% zinc, 12 g/t silver, 0.307 g/t gold and 0.03% lead for 4.34% zinc-equivalent over 10.9 metres, starting at 432.7 metres in downhole depth
  • (including 0.69% copper, 4.49% zinc, 22.2 g/t silver, 0.217 g/t gold and 0.1% lead for 6.65% zinc-equivalent over 2.9 metres)
  • (and including 1.16% copper, 1.48% zinc, 12.8 g/t silver, 0.64 g/t gold and 0.01% lead for 4.91% zinc-equivalent over 3 metres)

Drilling will soon resume
at Confederation Lake’s
Fredart zone.

GL18-03

  • 0.13% copper, 1.13% zinc, 3.3 g/t silver, 0.044 g/t gold and 0.02% lead for 1.54% zinc-equivalent over 12.9 metres, starting at 563.1 metres
  • (including 0.2% copper, 1.93% zinc, 4.3 g/t silver, 0.083 g/t gold and 0.04% lead for 2.54% zinc-equivalent over 3.8 metres)
  • (which includes 0.11% copper, 2.69% zinc, 3.4 g/t silver, 0.04 g/t gold and 0.07% lead for 3.09% zinc-equivalent over 1.5 metres)
  • (and also includes 0.48% copper, 2.92% zinc, 8.5 g/t silver, 0.15 g/t gold and 0.05% lead for 4.28% zinc-equivalent over 1.3 metres)

True widths weren’t provided.

In early May the company released the program’s first hole, showing 5.15% zinc-equivalent over 12.85 metres.

Last year Pistol Bay filed a 43-101 resource for Arrow, with a base case 3% zinc-equivalent cutoff for an inferred category showing:

  • 2.1 million tonnes averaging 5.78% zinc, 0.72% copper,19.5 g/t silver and 0.6 g/t gold, for a zinc-equivalent grade of 8.42%

Contained amounts come to:

  • 274 million pounds zinc, 34.3 million pounds copper, 1.33 million ounces silver and 41,000 ounces gold

As the rig moves to the project’s Fredart copper-gold zone, the team keeps busy re-compiling all Arrow drill results and incorporating new surveys of collar locations and azimuths using differential GPS equipment, Pistol Bay stated.

Although Fredart underwent extensive drilling between 1965 and 1985, the zone lacks a 43-101 resource due to uncertainty about drill hole locations and the lack of previous core to confirm historic assays, the company added.

The drill campaign follows the 15,000-hectare property’s first survey by modern geophysics which, in another first for Confederation Lake, was conducted on a regional scale.

Emerita Resources steps out to cut 5.7% zinc over 8 metres in Brazil

June 7th, 2018

by Greg Klein | June 7, 2018

Three more holes from eastern Brazil’s Salobro zinc project have Emerita Resources TSXV:EMO encouraged about potential expansion to an historic, non-43-101 Vale NYSE:VALE estimate. The results follow the first two holes, released June 1, of a program that’s expected to sink 23 holes totalling about 3,500 metres. Seventeen holes have been finished so far.

Emerita Resources cuts 5.7% zinc over 8 metres in Brazil

DDH-007 stepped out 100 metres from an historic, non-43-101 interval of 6.09% zinc and 0.73% lead over 10.43 metres. The new intercept hit:

  • 5.7% zinc and 0.84% lead, for 6.54% zinc and lead, over 8 metres, starting at 239.5 metres in downhole depth
  • (including 8.82% zinc and 1.48% lead, for 10.3% zinc and lead, over 4 metres)

Two near-surface holes tested potential for a starter pit in an area where an historic, non-43-101 trench assay showed 1.35% zinc over 22 metres. The new assays show:

DDH-005

  • 4.59% zinc and 0.08% lead, for 4.67% zinc and lead, over 1.5 metres, starting at 65.82 metres

DDH-006A

  • 1.52% zinc and 0.01% lead, for 1.53% zinc and lead, over 3 metres, starting at 26 metres

True widths weren’t provided.

Scheduled for Q3 is a resource to update Vale’s now historic, non-43-101 estimate of 8.3 million tonnes averaging 7.12% zinc-equivalent, using a 3.5% zinc-lead cutoff. The campaign will also collect 400 kilograms of material for metallurgical tests.

Last week Emerita released the current program’s first two assays, showing 4.05% zinc and 1.24% lead over 9.62 metres, along with 5.15% zinc and 0.51% lead over 3.32 metres. The company also reported that new assays from Vale core showed consistency with historic results, easing the way to a 43-101 resource.

Emerita has a 75% stake in the 1,210-hectare property, with the remainder held by IMS Engenharia Mineral Ltda. The region’s infrastructure includes paved roads, rail, power and water.

Emerita also shares in a 50/50 joint venture on the Plaza Norte zinc-lead project in northern Spain’s Reocin mining district, where the company has drill permitting underway to update historic work.

In December the company closed an oversubscribed private placement of $4.24 million.

Drilling, re-sampling move Emerita Resources towards Q3 Brazilian zinc resource

June 1st, 2018

by Greg Klein | June 1, 2018

While a rig remains busy, new assays from old core show consistency with historic results, bringing Emerita Resources TSXV:EMO closer to a 43-101 resource on its Salobro zinc project in eastern Brazil.

Drilling, re-sampling move Emerita Resources towards Q3 Brazilian zinc resource

Emerita Resources has assays pending from
another 15 holes so far on its current drill campaign.

The company sent 1,184 duplicate core samples from historic Vale NYSE:VALE drilling to the lab, where 55 samples with intervals grading over 1% zinc were considered for statistical purposes.

Compared with Vale’s data, the new assays demonstrate that “the previous historic results are consistent, unbiased and meet the QA/QC requirements to support a mineral resource estimate to NI 43-101 standards,” Emerita stated.

The results provide “a powerful advantage for the project that saves the company considerable time, money and effort,” commented chairperson David Gower. “The project has an abundance of high-quality historic drilling data that allows us to expedite the program as we develop the Salobro project further.”

At a 3.5% zinc-lead cutoff, Vale’s historic, non-43-101 estimate showed 8.3 million tonnes averaging 7.12% zinc-equivalent. Hoping to expand those numbers in a 43-101 resource planned for Q3, Emerita has so far completed 17 holes totalling 2,740 metres of an anticipated 23-hole, 3,500-metre program. Last week the company released results from the campaign’s first two holes:

DDH-001

  • 4.05% zinc and 1.24% lead for 5.29% zinc plus lead over 9.62 metres, starting at 257.9 metres in downhole depth
  • (including 9.74% zinc and 3.66% lead for 13.4% zinc plus lead over 2.72 metres)

DDH-002

  • 5.15% zinc and 0.51% lead for 5.66% zinc plus lead over 3.32 metres, starting at 108.38 metres

True widths weren’t provided. The program will also extract 400 kilograms of material for metallurgical tests.

Emerita closed its 75% acquisition of the 1,210-hectare property last March, retaining the right to pick up the other 25%. Regional infrastructure features paved roads, rail, power and water.

In northern Spain’s Reocín mining district the company has drill permitting underway for Plaza Norte, a zinc-lead 50/50 joint venture that also features considerable historic work and regional infrastructure.

Emerita closed an oversubscribed $4.24-million private placement in December.
