Emerita Resources releases first zinc-lead assays from its Salobro project in Brazil

May 23rd, 2018

by Greg Klein | May 23, 2018

The near-term goal is a 43-101 resource to replace an historic estimate as drilling continues at Emerita Resources’ (TSXV:EMO) Salobro zinc project in eastern Brazil’s Minas Gerais state. Out of a planned 23-hole, 3,500-metre campaign, the crew has so far sunk 15 holes totalling 2,133.9 metres, with the first two assays released May 23.

Infill hole DDH-001 was collared within 24 metres of an exceptional historic Vale NYSE:VALE interval of 10.39% zinc and 2.13% lead over 13.92 metres. The new hole revealed:

  • 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)

A high-grade historic zinc estimate from
Vale brought Emerita Resources to Brazil.

DDH-002 extended an historic mineralized zone approximately 30 metres up-dip, with an assay grading:

  • 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.

Vale’s historic, non-43-101 estimate came to 8.3 million tonnes averaging 7.12% zinc-equivalent using a 3.5% zinc-lead cutoff. Emerita hopes to increase those numbers in a 43-101 resource scheduled for July. The company filed a 43-101 technical report on the 1,210-hectare property in March.

The current program includes six large-diameter holes to collect 400 kilograms of material for metallurgical tests.

Emerita closed its 75% acquisition of Salobro in March, with the right to take on the remaining 25% from IMS Engenharia Mineral Ltda. The region’s infrastructure includes paved roads, cell phone reception, rail, power and water.

Emerita also partners in a 50/50 joint venture on Plaza Norte, a northern Spain zinc-lead project with considerable historic work and regional infrastructure that sits adjacent to the former Reocin mine that produced about 62 million tonnes averaging 11% zinc and 1.4% lead up to 2003. With drill permitting underway, Emerita could produce a maiden resource for Plaza Norte in early 2019.

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

Jobs, revenues, share prices benefit as higher commodity prices boost B.C. mining

Jobs, revenues, share prices benefit as higher commodity prices boost B.C. mining

A 75%/25% partnership of Copper Mountain Mining TSX:CMMC and Mitsubishi
Materials brought a former mine back into production, employing 430 workers.

 

The bull’s still not back but higher commodity prices continue to sustain a mood of cautious optimism among British Columbia miners, PricewaterhouseCoopers assures us. Its 50th annual report on B.C. mining sketched a broad picture of the province’s industry by surveying 13 companies, focusing on 15 operating mines, a smelter and seven projects in the exploration, permitting or environmental review stage.

Among survey participants, gross revenue hit $11.7 billion in 2017, a 35% jump from the previous year and reflecting an upward trend in the mining cycle. (Except for commodity prices, all figures are given in Canadian dollars.) Governments scooped up $859 million in total mining revenues from those companies last year, compared with $650 million in 2016.

Shareholders fared especially well, reaping 31.1% pre-tax gains from the companies involved, compared with 13.5% in 2016 and 6.3% in 2015. “This is the highest return we’ve seen in recent years and it has surpassed the historic high levels of 2012,” PwC stated.

Direct employment among the companies climbed to 10,196 jobs, compared with 9,329 in 2016 and 9,221 in 2015. PwC attributed most of the increase to Conuma Coal Resources’ two operating mines in the northeast.

Indeed, the participants’ metallurgical coal revenue rose to $5.2 billion from $3 billion in 2016 and $2 billion in 2015. Prices averaged $173 a tonne last year, up from $115 in 2016 and $101 in 2015. At a 50% increase over 2016, the steelmaking stuff struck the highest price increase of any commodity included in the report.

Revenue from copper concentrate came to nearly $1.9 billion, after $1.8 billion in 2016 and $2 billion in 2015. Average red metal prices rose 27% to $2.80 a pound, compared with $2.21 in 2016 and $2.50 in 2015.

Despite a slight decrease in shipments, a 38% price increase lifted participants’ zinc revenue to $1.2 billion, compared with $877 million in 2016 and $818 million the previous year. Prices swelled to an average $1.31 a pound, compared with $0.95 in 2016 and $0.87 in 2015.

Participants’ gold revenues rose to $829 million from $651 million in 2016 and $519 million in 2015. Although B.C. produces the yellow metal largely as a copper byproduct, the 2017 increase largely came from Pretium Resources’ (TSX:PVG) Brucejack mine, which began commercial production that year. Average prices underwhelmed, however, at $1,259 an ounce, although slightly less depressed than the $1,248 in 2016 and $1,160 in 2015.

Silver revenues slipped to $509 million from $589 million the previous year and $535 million in 2015. Average prices wallowed around $17.08 an ounce, compared with $17.11 in 2016, up from $15.71 in 2015. B.C. mines generally garner silver as a byproduct of metals like copper, gold, lead and zinc.

As for lead, it dropped to $224 million in revenues from $255 million the previous year, despite prices rising to $1.05 a pound from $0.85 in 2016.

Molybdenum more than doubled to $104 million from $45 million in 2016 and $51 million in 2015, thanks to higher volumes and prices, which reached $7.07 a pound from $6.37 in 2016.

[The return on shares for participating companies] is the highest return we’ve seen in recent years and it has surpassed the historic high levels of 2012.

Saying “the worst may be over,” PwC stated: “Many in the industry haven’t felt this positive since it was recovering from the fallout of the 2008-09 global financial crisis. There’s cautious optimism the industry will continue to recover.”

But a warning came from an otherwise upbeat Bryan Cox, president of the Mining Association of B.C.: “Mining projects are capital-intensive, multi-year commitments, from exploration to mine development and operation, necessitating clarity, consistency and co-ordination from governments for investors to deploy capital. If any one of those three Cs is missing, then capital investment is at risk.”

This marks PwC’s 50th such report since 1967, when “Lester B. Pearson was Canada’s prime minister, W.A.C. Bennett was the premier of British Columbia and [get this!] the Toronto Maple Leafs won the Stanley Cup. As for mining, in 1967 the price of gold was about $35 per ounce, copper was trading around $0.50 per pound and the Britannia mine, now a museum, was still producing copper, gold, silver and other metals and minerals.”

Pistol Bay drills 5.15% zinc-equivalent over 12.85 metres at NW Ontario’s Confederation Lake

May 3rd, 2018

by Greg Klein | May 3, 2018

With three holes totalling 1,525 metres now complete out of a 3,500-metre winter-spring campaign, Pistol Bay Mining TSXV:PST released the first assay on May 2. The initial holes targeted the Arrow zone, part of the 100%-optioned, 15,000-hectare Confederation Lake project in northwestern Ontario.

Sunk on Arrow’s main sulphide zone, hole DDH GL18-02 gave up Russian doll interval-within-interval assays as follows:

Pistol Bay drills 5.15% zinc-equivalent over 12.85 metres at NW Ontario’s Confederation Lake

Pistol Bay hopes to upgrade last year’s
resource estimate for the project’s Arrow zone.

  • 3.07% zinc, 0.42% copper, 0.12% lead, 22.2 g/t silver and 0.59 g/t gold for 5.15% zinc-equivalent over 12.85 metres, starting at 422.95 metres in downhole depth
  • (including 3.82% zinc, 0.5% copper, 0.15% lead, 27.3 g/t silver and 0.71 g/t gold for 6.33% zinc-equivalent over 9.8 metres)
  • (which includes 4.83% zinc, 0.56% copper, 0.15% lead, 26.4 g/t silver and 0.45 g/t gold for 7.13% zinc-equivalent over 7.3 metres)
  • (which includes 8.88% zinc, 0.92% copper, 0.38% lead, 44.3 g/t silver and 0.38 g/t gold for 12.3% zinc-equivalent over 2 metres)
  • (which includes 22% zinc, 0.28% copper, 0.77% lead, 74.9 g/t silver and 0.77 g/t gold for 24.8% zinc-equivalent over 0.6 metres)

Overlapping some of these intervals was a three-metre section described as “conspicuous gold enrichment towards the top of the main sulphide zone”:

  • 0.83% zinc, 0.33% copper, 0.17% lead, 40.4 g/t silver and 1.65 g/t gold for 4.41% zinc-equivalent over 3 metres, starting at 426 metres

A 43-101 resource released last year for Arrow used 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

But recent drilling suggests Arrow might consist of “two separate zones arranged en echelon or that the southwestern part is displaced from the northeastern part by a fault,” Pistol Bay stated.

Still to come are assays for the two remaining holes.

From Arrow, the rig moves about eight kilometres west to sink three more holes on the property’s Fredart A zone, also known as Copperlode A. Work dating to the 1960s resulted in two conflicting historic, non-43-101 estimates of 386,000 tonnes averaging 1.56% copper and 33.6 g/t silver, or 219,500 tonnes averaging 1.95% copper and 41.8 g/t silver.

The drill program follows last year’s VTEM-Plus survey, the area’s first exposure to state-of-the-art regional geophysics.

Emerita Resources mobilizes rigs to Brazilian zinc project, plans mid-year resource

April 10th, 2018

by Greg Klein | April 10, 2018

With one or more rigs now en route, Emerita Resources TSXV:EMO has field staff preparing its Salobro zinc project for a 3,500-metre program and a late-Q2 resource estimate. Located in eastern Brazil’s Minas Gerais state, the 1,210-hectare property has an historic, non-43-101 estimate compiled by Vale NYSE:VALE of 8.3 million tonnes averaging 7.12% zinc-equivalent using a 3.5% zinc-lead cutoff.

Emerita Resources mobilizes rigs to Brazilian zinc project, plans mid-year resource

Regional infrastructure includes paved roads,
cell phone service, rail, water and power.

“We see excellent potential to expand the existing resource and the previous work completed by Vale was to a high technical standard, which provides an excellent base from which to accelerate the evaluation of the project,” said Emerita chairperson David Gower.

The company closed its 75% acquisition of Salobro in March, retaining the right to pick up the other 25% from IMS Engenharia Mineral Ltda. Also last month, Emerita filed a 43-101 technical report on the property.

As part of the resource update work, Emerita has assays pending for resampled core from 10 selected historic holes and has relogged 11 holes.

Additionally, an engineering firm has completed a preliminary mine plan for the project. Emerita also has a community engagement proposal under review.

The work comprises part of an ambitious campaign that might reach pre-feasibility as early as next year.

In northern Spain, meanwhile, the company takes part in a 50/50 joint venture on Plaza Norte, another zinc-lead project with substantial historic work and regional infrastructure. Emerita has permitting underway for a drill campaign that could bring a maiden resource early next year.

The company closed an oversubscribed private placement of $4.24 million in December.

Emerita Resources fast-tracks high-grade zinc in Brazil and Spain

by Greg Klein

Two years of escalating prices and several years of historic work have Emerita Resources TSXV:EMO in an exceptionally sanguine mood. Following December’s oversubscribed $4.24-million cash infusion and last month’s TSXV approval to close the Brazilian acquisition, the company announced a breathtakingly ambitious timeline for its Salobro zinc project. Should all go to a very optimistic plan, the company would advance from updating an historic resource to completing pre-feas and mine permitting within two to three years.

Emerita Resources fast-tracks high-grade zinc in Brazil and Spain

Should success reward optimism, Salobro
could reach pre-feasibility next year.

The 1,210-hectare former Vale NYSE:VALE project’s located in southeastern Brazil’s Minas Gerais state, where regional infrastructure includes a zinc smelter, paved roads, rail, water and power.

Salobro comes with an historic, non-43-101 Vale-compiled resource of 8.3 million tonnes averaging 7.12% zinc-equivalent lying at shallow depth and showing expansion potential along strike and down dip. The geology suggests either a Mississippi Valley-type or sedimentary exhalative deposit, Emerita says. A standout among historic intervals assayed 10.39% zinc and 2.13% lead over 13.92 metres.

The acquisition would give Emerita a 75% stake in Salobro and the right to pick up the remaining 25% from IMS Engenharia Mineral Ltda. Vale, meanwhile, has begun the process of withdrawing a civil claim against IMS concerning ownership of the property, Emerita stated. The company expects to close the deal by the end of March.

“Ambitious” might be an understatement for such an optimistic timeline. But the project “has consistently exceeded our expectations during our scoping and analysis phase,” says newly appointed CEO Michael Timmins. The veteran of Agnico Eagle Mines’ (TSX:AEM) expansion from one to nine operations adds, “We are encouraged by the outcome of this early mine study and are very excited to have the opportunity to utilize our award-winning mine-building team in Brazil to fast-track the development of Salobro.”

With that in mind the company foresees a 43-101 technical report filed by the end of March, a 43-101 resource by the end of Q2, 3,500 metres of exploration drilling to begin in early March, a PEA complete by the end of Q3, baseline enviro studies beginning in Q3, a pre-feas finished by Q3 2019 and mine development permits in hand by Q2 2020.

Obviously such an agenda depends on favourable outcomes at every stage. The company has already been resampling historic core for the new resource, which will also include upcoming step-out holes to expand the deposit’s shallow areas. A conceptual mine plan will build on info inherited from Vale.

Emerita credits its Brazilian team with significant involvement in projects including Belo Sun Mining’s (TSX:BSX) Volta Grande gold project and Aguia Resources’ (TSXV:AGRL) Tres Estradas phosphate deposit.

The deal calls for Emerita to pay Vale an initial US$350,000 after IMS turns Salobro over to a subsidiary held 75% by Emerita and 25% by IMS. Once Vale formally withdraws its claim against IMS, Emerita pays Vale legal costs of approximately 760,000 reals, about C$297,000. Further payments to Vale would cost Emerita US$1.65 million by July 14, US$1.5 million in 2020 and another US$3 million in 2024.

Emerita may buy out the IMS 25% for C$2 million and a million shares by 2021.

Emerita Resources fast-tracks high-grade zinc in Brazil and Spain

The Plaza Norte agenda aims for a late-
2019 preliminary economic assessment.

Helping on the financial side will be December’s oversubscribed $4.24-million private placement. But some of that cash will go to another Emerita zinc project—and for that, the focus shifts to northern Spain.

Situated next to the former Reocin mine that produced about 62 million tonnes averaging 11% zinc and 1.4% lead up to 2003, the 3,600-hectare Plaza Norte property sits amid regional infrastructure including rail, road and port facilities, along with a Glencore zinc smelter about 180 road kilometres away. The project is a 50/50 JV with the Aldesa Group, a specialized construction and infrastructure firm operating in Spain and internationally.

Emerita’s Spanish team now has permitting underway for a 5,000-metre campaign anticipated to start in May. The plan is to build a 43-101 resource over an area that’s already seen more than 300 holes totalling about 73,000 metres. Some historic intercepts include 9.72% zinc and 0.09% lead over 18.96 metres, along with 7.05% zinc and 0.3% lead over 8.2 metres. The company anticipates an initial resource in Q1 next year and a PEA by 2019 year-end.

Meanwhile Emerita awaits resolution of disputed ownership concerning two other Spanish zinc properties, Paymogo and Aznalcollar. The latter’s Los Frailes deposit hosts an historic, non-43-101 estimate showing 20 million tonnes averaging 6.65% zinc, 3.87% lead, 0.29% copper and 148 ppm silver. The company considers the project ready for feasibility studies.

Paymogo’s La Infanta deposit has another historic, non-43-101 estimate of 800,000 tonnes averaging 1.77% copper, 6.91% lead, 12.66% zinc and 148 g/t silver. About seven kilometres away, Paymogo’s Romanera deposit holds an historic, non-43-101 34 million tonnes averaging 0.42% copper, 1.1% lead, 2.3% zinc, 44 g/t silver and 0.8 g/t gold.

Resource update precedes PEA for Golden Dawn Minerals’ newest B.C. gold-polymetallic project

January 23rd, 2018

by Greg Klein | January 23, 2018

Update: On February 6, 2018, Golden Dawn Minerals reported that Huakan International Mining, which optioned J&L to Golden Dawn, faced a lawsuit from Armex Mining, which claims it has a valid letter of intent with Huakan concerning J&L. Huakan intends to defend the Armex action, Golden Dawn added.

Calling it one of western Canada’s “largest undeveloped gold mineral resources,” Golden Dawn Minerals TSXV:GOM released a new estimate for J&L, a southern British Columbia project acquired just last month. The company now expects to finish a preliminary economic assessment within five to eight months for a project that will be developed separately from the Greenwood portfolio farther south, where Golden Dawn plans to revive three former mines and a nearby mill.

Totals for four zones at J&L showed:

  • measured and indicated: 5.16 million tonnes averaging 4.59 g/t gold and 55.6 g/t silver for 761,000 ounces gold and 9.23 million ounces silver

  • inferred: 4.8 million tonnes averaging 4.35 g/t gold and 60.6 g/t silver for 672,000 ounces gold and 9.37 million ounces silver
Resource update precedes PEA for Golden Dawn Minerals’ newest B.C. gold-polymetallic project

The highway-accessible property came with a rail siding and loading facility 35 kilometres south in Revelstoke, as well as a 40-person camp, maintenance buildings, workshops and underground mining equipment.

Incorporating lead and zinc grades, the company attributed 1.35 million gold-equivalent ounces to M&I and another 1.07 gold-equivalent ounces to the inferred category.

The four zones comprise Main, Yellowjacket, Hanging Wall and Footwall. Main extends over 1.5 kilometres along strike and 850 metres down dip, remaining open for expansion, the company stated.

Meanwhile the Greenwood revival continues as Golden Dawn prepares to begin trial mining at the Lexington gold-copper past-producer within months. The company’s busy, multi-project activities are summarized here.

Saville Resources moves into Commerce Resources’ niobium-tantalum target

by Greg Klein

A rare metal find on a property hosting a rare earths deposit becomes a project of its own under a new agreement between two companies. With a 75% earn-in, Saville Resources TSXV:SRE can now explore the niobium claims on Commerce Resources’ (TSXV:CCE) Eldor property in northern Quebec, where the latter company advances its Ashram rare earths deposit towards pre-feasibility.

Saville Resources moves into Commerce Resources’ niobium-tantalum target

A map illustrates the mineralized boulder
train’s progress, showing its presumed source.

Grab samples collected by Commerce on a boulder train about a kilometre from the deposit brought assays up to 5.9% Nb2O5. “That’s right off the charts,” enthuses Saville president Mike Hodge. “People in the niobium space hope for 1%—5.9% is excellent.”

He’s no newcomer to the space or even to the property. Hodge helped stake Commerce’s tantalum-niobium deposit on southern British Columbia’s Blue River property, which reached PEA in 2011.

“I did a lot of the groundwork for Commerce in the Valemount-Blue River area and I was one of the first guys on the ground at the camp that now supports Ashram,” he points out. “I’ve been involved with these two properties since 1999.” That’s part of a career including field experience on over 25 projects as well as raising money for junior explorers.

Miranna’s grab samples brought tantalum too, with a significant 1,220 ppm Ta2O5. Forty of the 65 samples graded over 0.5% Nb2O5, with 16 of them surpassing 1%.

The company describes the sampling area as a “strongly mineralized boulder train with a distinct geophysical anomaly at its apex.”

The 980-hectare Eldor Niobium claims have also undergone drilling on the Northwest and Southeast zones, where some wide intervals gave up 0.46% Nb2O5 over 46.88 metres and 0.55% over 26.1 metres (including 0.78% over 10.64 metres).

Samples from Miranna and the Southeast zone also show that niobium-tantalum occurs within pyrochlore, described by Saville as the dominant source mineral for niobium and tantalum in global mining. That’s the case, for example, at Quebec’s Niobec mine, one of the world’s three main niobium producers, with 8% to 10% of global production. Moreover, pyrochlore on the Saville project “is commonly visible to the naked eye, thus indicating a relatively course grain size, which is a favourable attribute for metallurgical recovery,” the company added.

Hodge already has a prospective drill target in mind. “I pulled the rig around with a Cat for a lot of the holes on Ashram itself so I’m very familiar with the ground. We’d of course do more prospecting and try to prove up some more numbers while we’re drilling.”

Saville Resources moves into Commerce Resources’ niobium-tantalum target

Should Saville find success, a ready market would be waiting. The company cites niobium demand growth forecasts of 7.66% CAGR from 2017 to 2021. A December U.S. Geological Survey report lists niobium and tantalum among 23 minerals critical to American security and well-being.

The country relies on foreign exports for its entire supply of both minerals, according to an earlier USGS study. From 2012 to 2015, 80% of America’s total niobium imports came from Brazil, where one mine alone produces 85% to 90% of global supply. Looking at tantalum imports during that period, the U.S. relied on China for 37% and Kazakhstan for another 25%. A troubling source of tantalum remains the Democratic Republic of Congo, from where conflict minerals reach Western markets through murky supply chains.

Days after the USGS released its December study, American president Donald Trump ordered a federal strategy “to ensure secure and reliable supplies of critical minerals.” Although he emphasized the need for domestic deposits and supply chains, Trump also called for “options for accessing and developing critical minerals through investment and trade with our allies and partners.”

Meanwhile Saville also sees potential in Covette, the company’s other northern Quebec property. Historic, non-43-101 grab samples reported up to 4.7% molybdenum, with some bismuth, lead, silver and copper. A 1,402-line-kilometre VTEM survey in late 2016 found prospectivity for base and precious metals. “The VTEM and some sampling that we did indicates that drilling could find something valuable,” Hodge says. “Although it is early-stage, the Geotech guys that did the VTEM survey said they hadn’t seen targets like that all year.”

Still, “the niobium claims are my first priority,” Hodge emphasizes. “I’m very excited about this. I believe we can have a winning project here.”

Subject to approvals, a 75% interest in the new property would call for $25,000 on signing, another $225,000 on closing and $5 million in work over five years. Commerce retains a 1% or 2% NSR, depending on the claim, with Saville holding a buyback option.

Last month the company offered private placements totalling up to $500,000, with insiders intending to participate.

Step-out drilling grows potential of Rockcliff Metals’ historic zinc deposit in Manitoba

A late autumn drill campaign on one of the priority properties in Rockcliff Metals’ (TSXV:RCLF) extensive Snow Lake portfolio shows potential to expand the historic Bur zinc-polymetallic deposit. Assays from 10 step-out holes totalling 3,250 metres brought zinc grades up to 3.18%, with 7.2% zinc-equivalent, over 4.85 metres. Another star result showed 1.76% zinc, with 5.9% zinc-equivalent, over 6.91 metres.

Each hole intersected the Bur VMS horizon, a potentially 8,000-metre-long mineralized area hosting the historic deposit adjacent and to the northeast of the drill targets, stated president/CEO Ken Lapierre. “The potential to identify additional resources along this important horizon is considered excellent and will be the focus of upcoming drill programs.”

Some highlights from the most recent campaign show:

Hole RBU002

  • 1.76% zinc, 0.96% copper, 0.59% lead, 0.26 g/t gold and 32.76 g/t silver, for 5.9% zinc-equivalent over 6.91 metres, starting at 269.65 metres in downhole depth
  • (including 0.99% zinc, 2% copper, 0.86% lead, 0.57 g/t gold and 56.35 g/t silver, for 9.1% zinc-equivalent over 2.43 metres)

RBU005

  • 1.65% zinc, 1.84% copper, 0.15% lead, 0.05 g/t gold and 15.32 g/t silver, for 6.8% zinc-equivalent over 4.25 metres, starting at 302.82 metres
  • (including 0.5% zinc, 6.18% copper, 0.08% lead, 0.04 g/t gold and 31.31 g/t silver, for 16.9% zinc-equivalent over 0.96 metres)

RBU007

  • 3.18% zinc, 1.41% copper, 0.13% lead, 0.04 g/t gold and 13.25 g/t silver, for 7.2% zinc-equivalent over 4.85 metres, starting at 231.15 metres
  • (including 5.38% zinc, 1.95% copper, 0.2% lead, 0.05 g/t gold and 15.62 g/t silver, for 10.9% zinc-equivalent over 2.85 metres)

True widths weren’t available.

Dating to 2007, Bur’s historic, non-43-101 estimate used a zinc-equivalent cutoff of 5%:

  • indicated: 1.05 million tonnes averaging 8.6% zinc, 1.9% copper, 12.1 g/t silver and 0.05 g/t gold

  • inferred: 302,000 tonnes averaging 9% zinc, 1.4% copper, 9.6 g/t silver and 0.08 g/t gold

Rockcliff’s 100% earn-in from Hudbay Minerals TSX:HBM requires $3 million in spending over four years. Hudbay owns a copper-zinc concentrator about 22 kilometres by road from Bur.

Earlier this month Rockcliff released a resource update for its Talbot flagship, another VMS property in the company’s roughly 45,000-hectare central Manitoba Snow Lake portfolio. The package includes gold projects too. Last month the company reported 17 geophysical anomalies over the Laguna property, site of a former gold mine.

With three of the projects active, Rockcliff’s entire portfolio sits within trucking distance of two Hudbay processing facilities. Included are two copper-polymetallic deposits with resource estimates, three zinc deposits with historic, non-43-101 estimates, five gold projects and a non-core zinc project recently optioned to Nevada Zinc TSXV:NZN.

Rockcliff closed an oversubscribed private placement of $1.35 million in August.

Update: On February 6, 2018, Golden Dawn Minerals reported that Huakan International Mining, which optioned J&L to Golden Dawn, faced a lawsuit from Armex Mining, which claims it has a valid letter of intent with Huakan concerning J&L. Huakan intends to defend the Armex action, Golden Dawn added.

Part of a strategy to gather advanced-stage to near-production properties, Golden Dawn Minerals TSXV:GOM has picked up another British Columbia project. Situated 35 kilometres north of Revelstoke and 600 kilometres east of Vancouver, the 3,052-hectare J&L gold-silver-base metals property will function separately from the company’s Greenwood mining camp revival in southern B.C.

J&L’s infrastructure includes a 40-person camp.

J&L comes with historic resources for three zones, paved highway and forestry road access, a rail siding and loading facility in Revelstoke, a 40-person camp, maintenance buildings, workshops and a fleet of underground mining equipment.

As part of a 2012 preliminary economic assessment, Huakan International Mining compiled a resource that Golden Dawn considers historic and non-43-101:

Main zone

  • measured and indicated: 3.95 million tonnes averaging 5.68 g/t gold and 56.5 g/t silver for 722,000 ounces gold and 7.18 million ounces silver

  • inferred: 4.34 million tonnes averaging 4.16 g/t gold and 57.8 g/t silver for 580,200 ounces gold and 8.06 million ounces silver

The company also reported M&I grades of 1.94% lead and 3.56% zinc, for a gold-equivalent grade of 8.56 g/t. The inferred category shows 1.82% lead and 2.72% zinc, for 6.76 g/t gold-equivalent.

Footwall zone

  • inferred: 363,000 tonnes averaging 3.65 g/t gold and 25.4 g/t silver for 42,500 ounces gold and 296,000 ounces silver

With 0.55% lead and 0.51% zinc, the gold-equivalent grade comes to 4.49 g/t.

Yellowjacket zone

  • indicated: 1 million tonnes averaging 0.21 g/t gold and 64.1 g/t silver for 6,900 ounces gold and 2.07 million ounces silver

  • inferred: 35,000 tonnes averaging 0.35 g/t gold and 81.9 g/t silver for 400 ounces gold and 91,000 ounces silver

The indicated category also showed 2.77% lead and 9.08% zinc, while base metals inferred grades came to 3.18% lead and 6.26% zinc.

The mineralized zones have been drilled up to 1.5 kilometres along strike and as much as 850 metres down-dip, remaining open.

A three-option agreement outlines several steps of cash payments and share issues to the vendor, as well as spending and work requirements to earn an initial 51% interest and subsequently full ownership of the project.

Underground rehab readies the
Lexington past-producer for trial mining.

Golden Dawn plans to update the 2012 PEA and, given positive results, conduct further work including underground drilling, decline and drift development and metallurgical tests to move towards pre-feasibility.

Meanwhile work continues at the Greenwood camp 500 kilometres east of Vancouver, where Golden Dawn hopes to re-start a number of former mines within 15 to 20 kilometres’ radius of the company’s 212-tpd mill. Earlier this month Golden Dawn released another batch of gold-copper assays from the Golden Crown past-producer. The nearby Lexington gold-copper past-producer has dewatering and underground rehab underway, part of a plan to begin trial mining. Given the infrastructure in place, Golden Dawn proposes to re-start the former mines without de-risking at the feasibility level.

The company also announced three personnel additions this month. Geological consultant Peter Cooper’s 41-year career includes work as chief geologist and operations manager for Kinross Gold’s (TSX:K) Kettle River operations, about 40 kilometres south of the Greenwood camp. He’s helped put three gold mines into operation, including Kinross’ Buckhorn mine, 20 kilometres from Lexington.

Another consulting geologist, Serguei Soloviev has worked on a number of B.C. and Yukon gold and copper projects as well as serving as Rio Tinto Exploration’s chief geologist for Russian operations from 2010 to 2016. Soloviev has written over 50 technical papers for peer-reviewed journals.

Diana Mark joins the team as VP of corporate affairs. With over 25 years’ experience in corporate and regulatory compliance, she’s been providing consulting services to the company since January.

In September Golden Dawn closed private placements totalling $2.3 million, followed by another $2.36 million last month.
