King’s Bay Resources samples 6% copper in Newfoundland, awaits Labrador cobalt assays

December 15th, 2017

by Greg Klein | December 15, 2017

A three-day Phase I field program in northern Newfoundland brought encouraging copper grades for King’s Bay Resources’ (TSXV:KBG) Trump Island project. Out of 15 samples taken from outcrop, four surpassed an upper detection limit of 1% copper, with results showing:

King’s Bay Resources samples 6% copper in Newfoundland, awaits Labrador cobalt assays

  • >10,000 ppm copper, 303 ppm cobalt and >6 ppm silver

  • >10,000 ppm copper, 1,213.6 ppm cobalt and 21.1 ppm silver

  • >10,000 ppm copper, 634.5 ppm cobalt and 27.4 ppm silver

  • >10,000 ppm copper, 272.3 ppm cobalt and 28.7 ppm silver

With those numbers from aqua regia digestion Ultratrace ICP-MS analysis, King’s Bay sent the first sample to a second lab for additional tests using ICP and ore grade analysis, with the following result:

  • 6.07% copper, 0.03% cobalt and 14.4 ppm silver

Grab samples don’t represent the entire property, King’s Bay cautioned. But the company sees further exploration warranted for next spring. The boat-accessible property’s historic work dates to historic times, when in 1863 a miner from Cornwall reportedly extracted a supply of copper and cobalt for shipment to Wales. Non-43-101 results from 1999 grab sampling near the Cousin Jack’s mineshaft showed 3.8% copper, 0.3% cobalt, 2.9 g/t gold and 10.9 g/t silver. The 200-hectare property has yet to be drilled.

Last month King’s Bay wrapped up an initial two-hole, 502-metre program at its Lynx Lake cobalt project in Labrador. Assays are expected in early January but the company reported intervals of net textured gabbro totalling 164.3 metres, along with a 14.9-metre intercept of mineralized biotite gabbro. The holes targeted the West Pit area, where the company anticipates a VTEM anomaly to range from 50 to 300 metres’ depth and about 400 metres in diameter. A highway and powerlines run through the 24,000-hectare property.

King’s Bay offered a $250,000 private placement in September.

Satellite imagery helps Belmont Resources home in on Nevada lithium targets

December 14th, 2017

by Greg Klein | December 14, 2017

Thanks to NASA and the U.S. Geological Survey, archived satellite data sharpens the focus on Belmont Resources’ (TSXV:BEA) Kibby Basin lithium project in Nevada. The company now has geophysics and other work planned for a busy new year.

Satellite imagery helps Belmont Resources home in on Nevada lithium targets

The satellite info shows hydrothermal indicator minerals over about one square kilometre of the 2,760-hectare property, CEO/president Vojtech Agyagos stated. “This area hosted the highest lithium surface samples as well and is the site of our proposed third drill hole. Our 2017 drill program discovered both water (fresh) and up to 200 ppm lithium in the core in the eastern side of the property about two kilometres from these thermal alterations.”

Drill results released last June showed clay-rich core samples grading between 70 ppm and 200 ppm lithium, “with 13 of 25 core samples assaying over 100 ppm lithium, indicating that the sediments could be a potential source of lithium for the underlying aquifers,” Belmont announced at the time.

Agyagos added that the satellite-revealed geothermal alteration “sits above the deepest gravity-indicated area from Belmont’s 2016 Wright geophysical ground gravity survey.”

Results from that survey suggest a basin model about 4,000 metres deep with similarities to Clayton Valley, host to Albemarle Corp’s (NYSE:ALB) Silver Peak lithium mine.

Belmont’s next plans call for a number of surveys including magnetotelluric, vertical electrical sounding, geothermal probe, electromagnetic resistivity and possibly seismic to help identify lithium brine drill targets. The company expects to finish EM work in early January.

Along with International Montoro Resources TSXV:IMT, Belmont holds a 50/50 stake in two northern Saskatchewan uranium properties, Crackingstone and Orbit Lake, for which the companies seek JV partners.

In New Brunswick last month, Belmont acquired the Mid Corner-Johnson Croft zinc-copper property, which shows promising historic sampling results but has yet to undergo modern geophysics.

Last week the company closed an oversubscribed private placement of $312,200.

Rockcliff Metals boosts its Talbot copper-polymetallic resource in Manitoba

December 8th, 2017

by Greg Klein | December 8, 2017

Among a number of active projects in the company’s Snow Lake portfolio, the Talbot deposit stands out as Rockcliff Metals’ (TSXV:RCLF) flagship. Now an updated resource has the company increasingly enthused while work continues towards further expansion.

The first update since January 2016 for the 51%-optioned property increases tonnage and contained amounts for an inferred category showing:

  • 4.23 million tonnes averaging 1.61% copper, 1.4% zinc, 1.77 g/t gold and 27.96 g/t silver for 150 million pounds copper, 130.4 million pounds zinc, 241,000 ounces gold and 3.8 million ounces silver
Rockcliff Metals boosts its Talbot copper-polymetallic resource in Manitoba

Based on 84 holes totalling 44,800 metres, the estimate uses a copper-equivalent cutoff of 2%. The copper-equivalent grade comes to 3.4%.

“The deposit remains open in all directions and is robust and predictable in all aspects including the geology, the estimation, classification and reporting assumptions,” said president/CEO Ken Lapierre. “Last year’s geophysics indicated significant upside potential to discover more VMS (copper, gold, zinc, silver) mineralization at the West Talbot deep conductive plate. Our present geophysical survey will focus on this large untested one-kilometre-by-one-kilometre anomaly, located immediately below and in the footwall of the deposit.”

Talbot has more drilling planned for 2018.

Featuring both gold and VMS projects, Rockcliff’s Snow Lake portfolio hosts five gold properties, two copper-polymetallic deposits with resource estimates and three zinc deposits with historic, non-43-101 estimates. All sit within trucking distance of two Hudbay Minerals TSX:HBM processing plants.

Reporting on the Laguna gold project last week, Rockcliff announced geophysics had located 17 high-priority anomalies, while winter plans include more surveying. A fall drill program at the Bur zinc-copper project had around 3,000 metres scheduled to upgrade the historic resource.

Golden Dawn’s Golden Crown gives up 27.2 g/t gold over 0.57 metres, 7.21 g/t over 0.73 metres in southern B.C.

December 5th, 2017

by Greg Klein | December 5, 2017

Another batch of assays shows more high grades from Golden Crown, one of the Greenwood camp past-producers Golden Dawn Minerals TSXV:GOM hopes to revive in southern British Columbia. This program has so far sunk 31 holes totalling 2,954 metres, as drilling continues. Including nine holes released in October, results for 18 reported holes show consistency with previously released intercepts, the company stated. Near-surface drilling targeted massive sulphide veins and adjacent wall rocks, with the most recent highlights including:

Hole GC17-12, King zone

  • 4.99 g/t gold and 0.12% copper over 1.5 metres, starting at 64.38 metres in downhole depth
Golden Dawn’s Golden Crown gives up 27.2 g/t gold over 0.57 metres, 7.21 g/t over 0.73 metres in southern B.C.

A key aspect of Golden Dawn’s plan to
revive Greenwood’s former mines is a
nearby 212-tpd processing facility.

GC17-14, Portal zone

  • 27.2 g/t gold and 0.11% copper over 0.57 metres, starting at 33.88 metres

  • 4.29 g/t gold and 0.07% copper over 1.3 metres, starting at 37.17 metres

GC17-16, Portal zone

  • 7.21 g/t gold and 0.24% copper over 0.73 metres, starting at 27 metres

  • 5.11 g/t gold over 2 metres, starting at 49.5 metres

GC17-18, Southwest zone

  • 41.4 g/t gold, 0.17% copper and 5.9 g/t silver over 0.3 metres, starting at 31.25 metres

True widths weren’t provided.

“The deposit now appears to consist of a field of multiple veins and veinlets, with the main vein structures selected as targets for underground development,” Golden Dawn stated.

Using a 3.5 g/t gold-equivalent cutoff, the 2016 resource shows:

  • indicated: 163,000 tonnes averaging 11.09 g/t gold, 0.56% copper and 11.93 g/t gold-equivalent for 62,500 gold-equivalent ounces

  • inferred: 42,000 tonnes averaging 9.04 g/t gold, 0.43% copper and 9.68 g/t gold-equivalent for 13,100 gold-equivalent ounces

Next year’s plans include increasing and upgrading the resource.

Drilling continues at the project, while the newly acquired JD zone and the three-kilometre trend extending to Golden Crown will see additional drilling next year. One-width intervals of chip samples from JD released in October assayed up to 15.8 g/t gold and averaged 7.4 g/t.

Other 2018 plans for Golden Crown include metallurgical studies as well as permitting for underground mine development and bulk sampling, part of a plan to enter production without de-risking through a feasibility study.

At the nearby Lexington past-producer, meanwhile, Golden Dawn has de-watering nearly complete, with trial mining scheduled to follow next year. That would coincide with wet commissioning at the company’s 212-tpd Greenwood mill, three kilometres from Golden Crown and 17 klicks from Lexington.

Last month Golden Dawn closed an over-subscribed private placement of $2.36 million that followed private placements totalling another $2.3 million that closed in September. Also in November, the company announced negotiations to pick up additional properties.

The current Greenwood portfolio sits about 500 kilometres by highway east of Vancouver.

More news from Rockcliff Metals as geophysics heightens interest in former Manitoba gold mine

November 30th, 2017

by Greg Klein | November 30, 2017

Just two days after announcing an adjacent acquisition, Rockcliff Metals TSXV:RCLF reported 17 high-priority geophysical anomalies on its Laguna gold project, one of several gold and VMS properties in the company’s Flin Flon-Snow Lake portfolio. The latest news comes from 40.5 kilometres of induced polarization and resistivity over the Laguna gold mine trend. Described as a five-by-one-kilometre gold-rich, sulphide-bearing quartz vein environment, the trend hosts a former mine that averaged about 19 g/t during intermittent operation between 1916 and 1939, producing over 60,000 ounces.

More news from Rockcliff Metals as geophysics heightens interest in former Manitoba gold mine

The survey’s tight spacing “allowed excellent surface resolution and superior depth penetration up to 250 metres vertical,” Rockcliff stated. The 17 anomalies “were strategically located mostly below and along strike of known gold-bearing sulphide-rich quartz veins and are all considered worthy of follow-up exploration,” the company added.

Winter plans call for more IP and resistivity along strike and in the footwall of the trend.

Noting that grab sample assays from the area ranged from trace to over 620 g/t, president/CEO Ken Lapierre said, “The Laguna gold mine trend was last drilled in 1944 and now definition of these new untested gold targets is a testament to the excellent untested gold potential at Laguna.”

Covering over 45,000 hectares in central Manitoba, Rockcliff’s Snow Lake portfolio includes five gold projects, two copper-polymetallic deposits with resource estimates, three zinc deposits with historic, non-43-101 estimates, and a non-core zinc project recently optioned to Nevada Zinc TSXV:NZN. The properties all sit within trucking distance of two Hudbay Minerals TSX:HBM processing facilities.

Rockcliff’s Bur zinc-copper deposit currently has drilling underway for about 15 holes totalling 3,000 metres, while the company’s 51%-optioned Talbot copper-zinc-polymetallic property has a resource update in progress.

Mountain Boy/Jayden hit 8.63 g/t over 7.72 metres in new Golden Triangle gold zone

November 28th, 2017

by Greg Klein | November 28, 2017

Strong assays from a previously unexplored area 550 metres northeast of the Silver Coin deposit indicate a new gold zone on the northwestern British Columbia property, according to the JV partners. With 80% and 20% interests respectively, Jayden Resources TSXV:JDN and Mountain Boy Minerals TSXV:MTB announced the discovery from a recently completed 14-hole, 2,226-metre program.

Highlights from five holes released November 28 include:

Mountain Boy/Jayden hit 8.63 g/t over 7.72 metres in new Golden Triangle gold zone

Magnificent scenery doesn’t distract attention
from high-grade gold at Silver Coin.

Hole SC17-444

  • 8.08 g/t gold and 4.7 g/t silver over 2 metres, starting at 94.03 metres in downhole depth
  • (including 13.7 g/t gold and 5.91 g/t silver over 1 metre)

SC17-445

  • 5.12 g/t gold and 91.3 g/t silver over 3 metres, starting at 35 metres

  • 5.38 g/t gold and 17.07 g/t silver over 7.3 metres, starting at 146.2 metres
  • (including 6.21 g/t gold and 12.06 g/t silver over 5.37 metres)
  • (and including 15.5 g/t gold and 17.1 g/t silver over 1 metre)
  • (and including 10.7 g/t gold and 18 g/t silver over 0.5 metres)

SC17-446

  • 5.9 g/t gold and 45.32 g/t silver over 1.8 metres, starting at 103.6 metres
  • (including 8.62 g/t gold and 42.6 g/t silver over 0.8 metres)

  • 14.6 g/t gold and 52.5 g/t silver over 1 metre, starting at 131.2 metres

SC17-452

  • 8.63 g/t gold and 11.99 g/t silver over 7.72 metres, starting at 16.46 metres
  • (including 17.69 g/t gold and 23 g/t silver over 3.2 metres)

  • 4.86 g/t gold and 5.68 g/t silver over 2.5 metres, starting at 77.82 metres
  • (including 6.46 g/t gold and 6.22 g/t silver over 1.5 metres)

  • 8.25 g/t gold over 1 metre, starting at 88.97 metres

True widths were estimated between 60% and 80%. More assays are pending.

As for the main Silver Coin deposit, using a 2 g/t gold cutoff its 2013 resource shows an inferred category of 967,000 tonnes averaging 4.39 g/t gold, 18.98 g/t silver, 0.64% zinc, 0.25% lead and 0.04% copper.

The 1,470-hectare property hosts a zone of faulting and shearing with mineralization up to 300 metres wide and 2.5 kilometres long, the JV partners stated. They consider Silver Coin to share many characteristics with the former Silbak-Premier mine five kilometres south, which produced an estimated 1.8 million ounces gold, 41 million ounces silver, 4.2 million pounds copper, 62 million pounds lead and 20 million pounds zinc.

Meanwhile Mountain Boy has been reporting high grades and visible gold from another Golden Triangle drill campaign, as the company’s 35%-held Red Cliff project advances towards its maiden resource.

A drill program on two contiguous Golden Triangle properties, Mountain Boy’s 100%-held BA and Surprise Creek silver-base metals projects, awaits analysis of results from an airborne VTEM and magnetic survey.

Having closed a $586,400 private placement in September, the company offered a $300,000 private placement last month.

Rockcliff Metals adds another gold property to its polymetallic package in Manitoba

November 28th, 2017

by Greg Klein | November 28, 2017

An “opportunist” acquisition increases the gold presence on Rockcliff Metals’ (TSXV:RCLF) Snow Lake portfolio. The 2,557-hectare Lucky Jack property borders the company’s Laguna project, host to a former mine and site of an airborne geophysical program last summer.

Limited exploration on Lucky Jack dates to the 1920s, when a shaft was reportedly sunk on a quartz vein system measuring about 1,000 metres long and up to 25 metres wide. Historic, non-43-101 results for 21 grab samples from the shaft area averaged 66 g/t gold.

Rockcliff Metals adds another gold property to its Manitoba gold/VMS package

Channel samples in 1982 showed non-43-101 assays including 11 g/t gold over 0.4 metres and 44.2 g/t over 1.4 metres, with gold values recorded over a 130-metre strike. Near-surface drilling in 1988 brought non-43-101 results of 8.9 g/t gold over one metre, 15.9 g/t over one metre, 19.6 g/t over 0.5 metres and 32.5 g/t over 0.5 metres.

About 1.7 kilometres west of the shaft, another near-surface hole sunk in 1985 brought non-43-101 intervals of 5.6 g/t gold over 0.3 metres, 11.5 g/t over 0.46 metres and 58.5 g/t over 0.4 metres. Samples taken about 5.5 kilometres northwest of the shaft brought non-43-101 assays up to 20.6 g/t gold.

Lucky Jack costs Rockcliff $77,250. Seven of the property’s 15 claims have a 2% NSR applicable, half of which Rockcliff may buy for $500,000 per 0.5%.

Although Rockcliff currently focuses on its VMS projects, Lucky Jack brings the company’s gold portfolio to five properties including Laguna, Dickstone North, Snow Lake and last month’s acquisition of Berry Creek.

The company’s Snow Lake package also includes two copper-polymetallic deposits with resource estimates and three zinc deposits with historic, non-43-101 estimates. The properties all sit within trucking distance of two processing facilities owned by Hudbay Minerals TSX:HBM.

Following Phase II drilling on the 51%-optioned Talbot copper-zinc-polymetallic property, Rockcliff has a resource update underway. Drilling resumed this month on the Bur zinc-copper deposit, with a program of about 15 holes totalling 3,000 metres.

Quebec acquisition brings Saville Resources precious, base and rare metals prospectivity

November 27th, 2017

by Greg Klein | November 27, 2017

A flurry of updates shows a new project, new faces and new financing for a rejuvenated Saville Resources TSXV:SRE. The company now moves into Quebec’s James Bay region by taking on the 3,370-hectare Covette property. Although it’s seen limited exploration so far, Covette underwent a 1,402-line-kilometre VTEM survey late last year, along with prospecting and sampling this year. The coincidence of EM conductors with magnetic highs suggests prospectivity for base and precious metals, the company reported. This year’s field program included pegmatite sampling for evidence of lithium.

Quebec acquisition brings Saville Resources precious, base and rare metals prospectivity

Of two historic, non-43-101 grab samples, one returned 4.7% molybdenum, 0.73% bismuth, 0.09% lead and 6 g/t silver; while the other showed 1.2 g/t silver and 0.18% copper.

An underlying greenstone belt could offer base and precious metals potential as well as pegmatite-hosted lithium and tantalum. “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,” the company stated.

Covette lies just 10 kilometres north of the all-weather Trans-Taiga road, which runs parallel to the LG-3 transmission line.

Pending TSXV approval, Saville gets the property by paying Zimtu Capital TSXV:ZC $350,000.

Additionally, Saville announced Michael Hodge’s appointment as president/CEO/director. Having started his career in 1999 on the staking program for Commerce Resources’ (TSXV:CCE) Blue River tantalum-niobium project in British Columbia, Hodge has field experience on over 25 exploration projects as well as success in raising capital for junior miners.

Jody Bellefleur joins Saville as CFO, bringing over 20 years’ experience as a corporate accountant for the sector.

Saville also announced a private placement of up to $270,000. The company closed an $857,300 placement in July. Among other updates, Saville settled $219,000 in debt by issuing shares and warrants that would represent 18.7% of the company’s outstanding shares.

Pistol Bay Mining wants to bring blockchain to resource companies

November 15th, 2017

Update: On November 20 Pistol Bay announced it had created a subsidiary called PB Blockchain Inc to create applications for mining and resource companies.

by Greg Klein | November 15, 2017

While still focused on its Confederation Lake zinc-copper portfolio in northwestern Ontario, Pistol Bay Mining TSXV:PST sees untapped potential in technology’s current upheaval. The company reports ongoing discussions to form a wholly owned subsidiary that would create blockchain applications for the mining sector, as well as oil and gas and possibly other industries. Some products could include “Ethereum smart contracts, security, claim management, resource management and the tokenization of resources,” Pistol Bay stated.

Pistol Bay Mining wants to bring blockchain to resource companies

“We believe a unique opportunity exists to lead the mineral development industry by building a resource-focused blockchain company to facilitate modern mining-related transactions,” explained president/CEO Charles Desjardins. “This represents an exciting opportunity for the shareholders of Pistol Bay and, as a founder of the original Investment.com portal, I have always recognized the need to be early in adapting to new technologies.”

Back to mineral exploration, last month Pistol Bay announced confidentiality agreements with two companies interested in partnering on Pistol Bay’s 17,000-hectare Confederation Lake properties. One company was described as a mid-tier producer, the other a junior explorer. The news followed completion of the first regional and modern geophysical program carried out over the VMS-rich greenstone belt.

Having already received an exploration permit for Confederation Lake’s Dixie claims, Pistol Bay now has applications pending for the Garnet, Fredart, Moth and Fly claim groups. “With zinc prices at a record high, there’s lots of demand for zinc and copper exploration projects,” said Desjardins. “Not many companies can offer a belt-wide property base with proven VMS mineralization and a new airborne EM survey with multiple untested targets.”

Resource update underway for Rockcliff Metals’ Talbot copper property in Manitoba

November 15th, 2017

by Greg Klein | November 15, 2017

One of a number of active projects in Rockcliff Metals’ (TSXV:RCLF) Flin Flon-Snow Lake portfolio, the Talbot copper property has an updated resource estimate in the works. The initiative follows Phase II drilling and will accompany a DPEM geophysical survey on the West Talbot deep conductive plate, below and west of the deposit. In April the company announced finding VMS mineralization within the plate.

Resource update underway for Rockcliff Metals’ Talbot copper property in Manitoba

While analyzing this year’s drilling data for a resource update,
Rockcliff will conduct geophysics to help identify 2018 targets.

Rockcliff holds a 51% option on Talbot from Hudbay Minerals TSX:HBM.

Last spring’s drill campaign “identified additional areas of high-grade enrichment in the hanging wall and along strike of the present resource,” said president/CEO Ken Lapierre. “The additional DPEM geophysical survey will help us vector in on the exact up-dip location of the West Talbot deep conductive plate. The Talbot copper deposit was originally identified as a smaller geophysical conductive plate so any new larger plates identified in this area are viewed as high-priority targets.”

Dating to January 2016, Talbot’s current resource shows an inferred category for three zones:

Main zone

  • 1.44 million tonnes averaging 3.4% copper, 2.6 g/t gold, 2.4% zinc and 61 g/t silver for 107 million pounds copper, 118,600 ounces gold, 76.4 million pounds zinc and 2.83 million ounces silver

Footwall zone

  • 443,900 tonnes averaging 2.2% copper, 2 g/t gold, 2.4% zinc and 55.6 g/t silver for 22 million pounds copper, 28.5 ounces gold, 23.2 million pounds zinc and 793,800 ounces silver

North lens

  • 283,400 tonnes averaging 0.7% copper, 2 g/t gold, 1.3% zinc and 20.6 g/t silver for 4.6 million pounds copper, 18,300 ounces gold, 7.9 million pounds zinc and 187,600 ounces silver

Total

  • 2.17 million tonnes averaging 2.8% copper, 2.4 g/t gold, 2.2% zinc and 54.6 g/t silver for 133.6 million pounds copper, 165,400 ounces gold, 107.4 million pounds zinc and 3.81 million ounces silver

Rockcliff expects work to be completed by year-end, with results to be released once analyzed. Talbot has more drilling planned for 2018.

Active on several Snow Lake assets, the company began another drill campaign last week at the Bur zinc-polymetallic property. See a roundup of recent Rockcliff news here.
