Update: Pistol Bay Mining announces 43-101 resource, JV discussions and—again—newly staked land

September 20th, 2017

by Greg Klein | Updated September 20, 2017

Update: With staking announced on September 14 and 20, Pistol Bay Mining has added more than 5,860 hectares to its property package, bringing the total to about 17,000 hectares.

Results from Confederation Lake’s first regional state-of-the-art geophysics have prompted Pistol Bay Mining TSXV:PST to expand its presence in the VMS-rich northwestern Ontario greenstone belt. Two acquisition announcements came within eight days after the company reported initial findings from the 2,100-line-kilometre VTEM-Plus survey. Those results accompanied announcements of a new resource estimate for one of the portfolio’s projects as well as potential joint venture interest.

“We are seeing lots of new anomalies in the survey data, not just conductors but the IP effect anomalies as well, and Pistol Bay is going to have a busy few years exploring them all,” said CEO Charles Desjardins.

The new claims cover multiple conductors and IP-effect anomalies, some of which have had previous drilling with results showing zinc or copper, the company stated. The new data also shows parallel conductors or extensions of known conductors.

New claims between Pistol Bay’s Fredart and Joy claim groups host four conductors of 400, 850, 900 and 950 metres that appear not to have undergone drilling. Fredart A holds an historic, non-43-101 copper estimate. Like the four newly found anomalies, the Joy North anomaly hasn’t been drilled.

The airborne survey confirmed conductivity at all of the portfolio’s historic showings, zones and mineralized drill intercepts, Pistol Bay added. While analysis continues, data so far shows conductivity extending beyond known zones, along strike and in new clusters apart from known mineralization.

Once we’ve got our targets finalized, we will be entertaining proposals for joint ventures to advance this highly prospective property.—Charles Desjardins,
CEO of Pistol Bay Mining

“Because of the large number of potential targets generated by the VTEM survey, we are considering inviting joint venture partners for all or parts of the Confederation Lake project,” Desjardins noted. “We have had early-stage discussions with potential joint venture partners. Once we’ve got our targets finalized, we will be entertaining proposals for joint ventures to advance this highly prospective property.”

Pistol Bay also filed a technical report for Garnet Lake, a Confederation Lake property that hosts the Fredart A zone. Updating an historic 2007 estimate for the Arrow zone, the 43-101 incorporates 20 additional holes. Using a base case 3% zinc-equivalent cutoff, an inferred category shows:

  • 2.1 million tonnes averaging 0.72% copper, 5.78% zinc, 19.5 g/t silver and 0.6 g/t gold, for a zinc-equivalent grade of 8.5%

Contained amounts come to:

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

Contingent on favourable geophysical and other data, the 43-101 recommends two 1,000-metre holes at Arrow to test for possible down-plunge extensions of the resource. The report also calls for another 3,000 metres on targets to be identified elsewhere on the Garnet property.

Last May the company signed an LOI to acquire the 496-hectare Copperlode property, about four kilometres along strike from Arrow.

BonTerra Resources heralds new gold zone in Quebec’s Urban-Barry camp

September 14th, 2017

by Greg Klein | September 14, 2017

Exploration drilling southwest of the Gladiator deposit reveals a new gold zone, BonTerra Resources TSXV:BTR announced. Christened the Temica zone, it’s believed to be an extension of the deposit’s mineralized trend. Of three holes with one intercept each reported September 14, the standout was CL-17-14, four kilometres from the deposit. The result showed 4.7 g/t gold and 44.6 g/t silver over 2.7 metres, at 250 metres below surface.

BonTerra’s field camp houses a team
busy with a 40,000-metre 2017 program.

Another kilometre southwest, CL-17-06 found 13 g/t gold over one metre at 200 metres below surface. CL-17-01 showed a near-surface 4.8 g/t gold over one metre in “close proximity to drill hole CL-17-14, but was located too close to the zone and resulted in a partial intersection,” BonTerra stated.

True widths were estimated between 60% and 80%.

The discovery follows till sampling and induced polarization surveys that identified additional targets for further drilling that’s planned for Temica and beyond.

BonTerra last released assays in July from a campaign largely focused on the gap between the 8,126-hectare Coliseum property’s Gladiator deposit and the Rivage zone, about 600 metres west.

With at least four rigs busy on a planned 40,000 metres, all that drilling can only stir anticipation of an update to Gladiator’s 2012 resource. Using a base case 4 g/t cutoff, it holds an inferred category of 905,000 tonnes averaging 9.37 g/t for 273,000 ounces gold. The deposit remains open in all directions.

The company raised $40 million this year, with participation from Eric Sprott and Kinross Gold TSX:K.

BonTerra also holds the Larder Lake project in Ontario’s Cadillac/Larder Lake break. The property’s Bear Lake deposit has an historic, non-43-101 inferred resource of 3.7 million tonnes averaging 5.7 g/t for 683,000 gold ounces. Another non-43-101 estimate for the Cheminis deposit has an indicated 335,000 tonnes averaging 4.1 g/t for 43,800 gold ounces and an inferred 1.39 million tonnes averaging 5.2 g/t for 233,400 ounces.

Drilling, sampling, optioning: Mountain Boy Minerals updates B.C. activities

September 13th, 2017

by Greg Klein | September 13, 2017

Demonstrating that a diverse portfolio doesn’t necessarily mean idle properties, Mountain Boy Minerals TSXV:MTB updated several projects in northwestern British Columbia’s Golden Triangle.

Drilling has just resumed at Silver Coin, held 20% by Mountain Boy and 80% by joint venture partner Jayden Resources TSXV:JDN. Acting as operator is Sprott Mining Inc on a campaign of about 6,000 metres mostly focusing on stepouts. The agenda also calls for regional exploration on the 1,470-hectare property.

Silver Coin hosts a 2013 43-101 resource that uses a 2 g/t gold cutoff to show a total for four zones:

  • indicated: 702,000 tonnes averaging 4.46 g/t gold, 17.89 g/t silver, 0.88% zinc, 0.33% lead and 0.07% copper

  • inferred: 967,000 tonnes averaging 4.39 g/t gold, 18.98 g/t silver, 0.64% zinc, 0.25% lead and 0.04% copper
Drilling, sampling, optioning: Mountain Boy Minerals updates B.C. activities

Mountain Boy awaits assays from Red Cliff,
where core from five holes has revealed visible gold.

Drilling continues at the Red Cliff property, where 25 holes have been completed so far with assays pending. In July Mountain Boy reported visible gold in the program’s first five holes. Red Cliff also has sampling underway at the Lower Montrose and Waterpump zones. The latter has drilling planned, once sampling assays arrive.

Mountain Boy has a 35% interest in Red Cliff, with JV partner Decade Resources TSXV:DEC holding the rest. The ownership gets more complicated, however, now that the two companies have teamed up on additional claims to the southeast. The acquisition gives the JV an earn-in total of up to 80% of the extension, with 28% to be held by Mountain Boy and 52% by Decade. The size of neither the original Red Cliff property nor the additional claims was reported. Mountain Boy and Decade share overlapping management and directors.

TSXV approval came through earlier this month for Mountain Boy’s 100% options on the Surprise Creek and BA properties, both formerly 50/50 JVs with Great Bear Resources TSXV:GBR. Over $12 million of exploration has gone into the nearby projects over the last 10 years, revealing zones of high-grade zinc, lead and silver, as well as zinc, copper and silver.

Prior to a drill program expected later this month, the 7,472-hectare Surprise Creek has sampling underway on a large barite zone and on areas of VMS mineralization revealed by historic sampling. In July the company announced successful production of a barite concentrate that surpassed American Petroleum Institute standards. The mineral is considered essential to oil and gas exploration.

Additional sampling has taken place on the 9,489-hectare BA VMS project, just north of a 2016 channel sample result that returned 3.84% zinc, 1.25% lead and 108 g/t silver over 15 metres. That included a sub-interval of 5.31% zinc, 1.97% lead and 132 g/t silver over 7.5 metres.

Mountain Boy also optioned 60% of West George, a 288-hectare copper property adjacent to the company’s George copper project that the company now holds 100%. The original George has non-43-101 copper-silver-gold estimates. West George has sampling underway.

Meanwhile assays are pending for recent sampling from MB Silver, a project with historic, non-43-101 polymetallic estimates. In southern B.C., Mountain Boy plans to begin PEA studies on its 100%-held Manuel Creek zeolite project.

The company expects to soon close a private placement of up to $1 million.

Castle Silver Resources to study possible new plant and processing deal with Granada Gold Mine

September 11th, 2017

by Greg Klein | September 11, 2017

A gold milling arrangement now under consideration could offer synergies to two companies with overlapping management, directors and staff. Under an MOU signed by Castle Silver Resources TSXV:CSR and Granada Gold Mine TSXV:GGM, Castle Silver will study the potential installation of a 600-tpd gravity flotation plant at one of its northern Ontario properties. The facility would process feed from the proposed Granada gold mine across the Quebec border near Rouyn-Noranda. Castle Silver expects to complete the study in Q4.

Castle Silver Resources to study possible new plant and processing deal with Granada Gold Mine

Granada’s proposed mine reached pre-feas
in 2014 and a resource update in May.

A resource update released last May used a 0.39 g/t cutoff to show an in-pit measured and indicated total of 21.57 million tonnes averaging 1.16 g/t for 807,700 gold ounces. An underground inferred category for an area north of the potential open pit used a 1.5 g/t cutoff for 10.38 million tonnes averaging 4.56 g/t for 1.52 million ounces. Granada stated the new 43-101 supersedes the pre-feasibility report released in 2014.

The company describes its project as fully permitted, shovel-ready and one of the region’s largest undeveloped gold projects.

Meanwhile Castle Silver waits on assays for its namesake flagship, where summer drilling sunk 22 holes totalling 2,405 metres. Chip and bulk sampling results from the former underground silver mine have returned gold, cobalt and nickel grades in addition to silver. More bulk sampling is planned.

Castle Silver has raised $2.6 million since March.

Update: Berkwood Resources continues to drill visible graphite in Quebec

August 31st, 2017

by Greg Klein | updated August 31, 2017

Assays have yet to arrive, but two holes reported last week and another five on August 31 have all produced near-surface core with visible graphite from Berkwood Resources’ (TSXV:BKR) Lac Gueret South project. The Phase I program calls for nine more shallow holes between about 60 and 120 metres in depth.

The company cautioned that visible indications don’t necessarily coincide with significant grades. But the results do justify continuing the program as planned, Berkwood stated.

Lac Gueret South borders the property hosting Mason Graphite’s (TSXV:LLG) high-grade graphite deposit. A 2014 airborne EM survey over Berkwood’s land found several zones of high conductivity.

Last week’s news from the property’s Site #1 reported 3.1 metres and 38.29 metres of visible graphite from BK1-01-17, along with 2.7 metres and 9.9 metres from BK1-02-17. The depths corresponded with electromagnetic conductors.

Berkwood Resources continues to drill visible graphite in Quebec

The first seven holes have brought observable
encouragement to Berkwood Resources’ Lac Gueret South.

Among new findings from Site #2, about 110 metres north, BK1-03-17 displayed the right stuff in seven intervals ranging between 1.46 metres and 28.2 metres in width.

Another Site #2 hole, BK1-04-17 showed graphite “continuously from 26.7 metres to 79.24 metres in variable amounts and styles,” Berkwood stated.

At Site #3, another 65 kilometres north, BK1-05-17 revealed graphite over four intervals with thicknesses between 3.2 metres and 14.12 metres. BK1-06-17 brought intervals of 13.22 metres and 1.14 metres.

About 87 metres east, BK1-07-17 on Site #4 showed 5.94 metres of graphite.

True widths weren’t provided.

The company holds two land parcels adjacent to the Mason property, Berkwood’s 100%-optioned, 5,714-hectare Lac Gueret South and the 100%-held, 2,052-hectare Lac Gueret East. The properties sit about three hours by road from the deep-sea port of Baie-Comeau.

Last month the company announced acquisition of the Delbreuil property in Quebec’s Abitibi, where an historic, non-43-101 sample assayed 1,290 ppm lithium and 126 ppm tantalum. Historic drill results also showed zinc, nickel, copper, silver and cobalt.

In another energy mineral acquisition last June, Berkwood announced an agreement to take on the Cobalt Ford property, located about four hours’ driving time from Baie-Comeau. Historic, non-43-101 work suggests prospectivity for base metals as well as cobalt.

This week the company closed private placements totalling $985,180.

Castle Silver Resources assays more gold from Ontario cobalt-polymetallic project

August 31st, 2017

by Greg Klein | August 31, 2017

Phase I surface drilling originally planned for 1,500 metres has wrapped up on 22 holes totalling 2,405 metres as Castle Silver Resources TSXV:CSR sees new polymetallic potential from a former mine near Ontario’s Cobalt camp. Drill core assays are pending but re-evaluation of five chip samples ranged from 0.72 grams per tonne to 7.03 g/t gold, averaging 3.7 g/t. The original assays for the same samples, reported last June, averaged 1.06% cobalt, 5.3% nickel and 17.5 g/t silver. The samples were selected from 200 kilograms taken just inside the adit.

Castle Silver Resources assays more gold at Ontario cobalt-polymetallic project

An expanded drill program has Castle Silver Resources
anticipating results for precious, base and energy metals.

Castle Silver had the samples evaluated for gold after an 82-kilogram bulk sample of vein material showed 5.7 g/t gold, as well as 46.3 g/t silver and 1.48% cobalt in results reported last month.

More bulk sampling will follow now that IOS Services Géoscientifiques has tested the property’s vein structures with Niton portable XRF technology. The results will help identify targets for bulk sampling and underground drilling after the former mine’s drift has been rehabilitated.

Using a 14.8% cobalt concentrate produced from recently sampled material, Castle Silver plans tests with its proprietary Re-2OX hydrometallurgical process to produce cobalt hydroxide samples. The company also intends to gauge Re-2OX’s potential to recover lithium and cobalt from Li-ion batteries.

“We’re seeing the potential for a variety of mineralization types within the Castle mine, well beyond just the high-grade silver that was recovered intermittently during the 1900s,” said president/CEO Frank Basa. “CSR is well funded to carry out its plans for a strong operational finish to 2017.”

Last month the company closed a private placement of $897,500, bringing the total since March to nearly $2.6 million.

Golden Dawn Minerals prepares for B.C. underground trial mining this year

August 22nd, 2017

by Greg Klein | August 22, 2017

With a dewatering permit now in place, Golden Dawn Minerals TSXV:GOM moves closer to trial mining at Lexington, one of its Greenwood holdings in southern British Columbia. A previous company operated the mine from April to December 2008, extracting 5,486 ounces of gold, 3,247 ounces of silver and 860,259 pounds of copper, all of which was processed about 17 kilometres northeast at the Greenwood mill, now a key Golden Dawn asset.

The Greenwood flotation plant and gold gravity circuit play a
key role in Golden Dawn’s plans to revive nearby former mines.

As dewatering takes place, the company plans to rehabilitate the mine’s two ramps and surface infrastructure. Further rehab, definition drilling, mapping and sampling would follow completion of dewatering. With new data in hand, the company intends to compile a test mine program for zones between the 1,210-metre and 1,175-metre elevations without the additional derisking of a feasibility study.

Production methods under consideration include longhole open stoping, jumbo mining and jackleg/slusher mining.

Crushing equipment and the mill, with a 200-tonne-per-day capacity expandable to 400 tpd, are slated for minor upgrades and refurbishing to prepare them for run-of-mine gold-copper feed expected from Lexington by about mid-November.

The company estimates costs between $3 million and $3.5 million to rehabilitate the mine, extract 5,000 tonnes of feed and refurbish the mill.

The 2,020-hectare property has a 2016 resource that uses a 3.5 g/t gold-equivalent cutoff to show:

  • measured: 58,000 tonnes averaging 6.98 g/t gold, 1.1% copper and 8.63 g/t gold-equivalent for 16,100 gold-equivalent ounces

  • indicated: 314,000 tonnes averaging 6.38 g/t gold, 1.04% copper and 7.94 g/t gold-equivalent for 80,200 gold-equivalent ounces

  • inferred: 12,000 tonnes averaging 4.42 g/t gold, 1.03% copper and 5.96 g/t gold-equivalent for 2,300 gold-equivalent ounces

Lexington comprises one of several former mines in Golden Dawn’s extensive Greenwood portfolio, all proximal to the company’s mill about 500 kilometres east of Vancouver. Golden Dawn’s other nearby past-producing priorities include Golden Crown, with a 2016 gold-copper resource, and the May Mac silver-gold-polymetallic project.

King’s Bay prepares for Newfoundland copper-cobalt field program

July 26th, 2017

by Greg Klein | July 26, 2017

Update: Effective August 14, 2017, King’s Bay Gold begins trading as King’s Bay Resources TSXV:KBG.

Copper-cobalt findings dating to the 19th century have King’s Bay Gold TSXV:KBG about to begin Phase I exploration on its Trump Island project off Newfoundland’s northern coast. The company has a team ready to study historic data prior to geophysics and grab sampling on the 200-hectare property. Depending on results, Phase II could incorporate drilling.

King’s Bay prepares for Newfoundland copper-cobalt field program

The property’s exploration history dates to 1863, when a Cornish miner sunk a six-metre shaft to follow a zone of massive chalcopyrite. Mineralization reportedly expanded with depth but the technology of the time prevented further excavation. Nevertheless the Cousin Jack reportedly shipped to Wales high-grade copper-cobalt material archaically recorded as “40 pounds per fathom.”

Grab samples collected near the shaft in 1999 showed historic, non-43-101 results up to 3.8% copper, 0.3% cobalt, 2.9 g/t gold and 10.9 g/t silver.

Located seven miles south of the town of Twillingate, Trump Island has boat access to a highway 1.5 kilometres away.

Last month King’s Bay reported geophysical results from another copper-cobalt project, this one along a provincial highway in Labrador. Airborne VTEM over the 24,000-hectare Lynx Lake property revealed a shallow anomaly of high resistivity about 400 metres in diameter and 50 to 300 metres in depth. The results came from the project’s West Pit, where historic, non-43-101 grab samples showed up to 1.03% copper, 0.566% cobalt, 0.1% nickel, 5 g/t silver, 0.36% chromium, 0.39% molybdenum and 0.23% vanadium.

Lynx Lake’s summer agenda includes higher-resolution ground geophysics, possible stripping to expose bedrock south of the pit and follow-up work on historic soil samples on the property’s southeastern area, along with mapping and sampling over both areas.

The company’s portfolio also includes three Quebec properties with historic, non-43-101 cobalt results.

Earlier this month King’s Bay closed a first tranche totalling $316,250 of a private placement offered up to $725,000. The company expects to close the second tranche by the end of August. King’s Bay closed a previous financing of $938,752 in January.
