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.

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.

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.

Option reactivates Rockcliff Copper non-core zinc project

October 23rd, 2017

Update: As of November 2, 2017, the company’s name and stock symbol will change to Rockcliff Metals Corp TSXV:RCLF.

Less than three weeks after acquiring a new Manitoba property, Rockcliff Copper TSXV:RCU optioned another to Nevada Zinc TSXV:NZN. The 4,992-hectare MacBride zinc project comprises a non-core asset for Rockcliff, north of its core portfolio in the Flin Flon-Snow Lake camp. MacBride comes with a near-surface, historic and non-43-101 estimate of 1.82 million tonnes averaging 8.8% zinc, 0.3% copper, 0.1 g/t gold and 4.5 g/t silver that remains open in all directions.

Under terms of the 80% option, Nevada may earn 70% by issuing 200,000 shares, paying $200,000 over three years and spending $2.5 million over five years. On achieving 70%, Nevada may form a joint venture with Rockcliff or earn an additional 10% by paying Rockcliff $2 million to form an 80%/20% JV. Should either interest fall below 10%, that stake will convert to a 1% NSR or a 0.5% NSR on claims subject to a pre-existing royalty. On part of the property, the original vendor holds a 2% NSR, half of which may be purchased for $1 million.

Rockcliff president/CEO Ken Lapierre welcomed Nevada’s “financial capabilities, expertise and knowledge in exploring this high-grade zinc-copper asset.” Nevada president/CEO Bruce Durham and CFO Don Christie serve on Rockcliff’s board. “The disinterested directors of Rockcliff approved the option,” the company stated.

Earlier this month Rockcliff announced a 100% option to add a fourth gold property to its Snow Lake portfolio.

This year’s exploration includes a summer airborne geophysical survey over the former Laguna gold mine, surface exploration on Laguna as well as two other gold projects, Dickstone and Snow Lake, and a planned fall drill program.

Along with gold, the company’s Snow Lake package includes VMS deposits. Among them, the Bur zinc-polymetallic project also has fall drilling scheduled. A spring drill program at Rockcliff’s 51%-optioned Talbot property found a new VMS zone.

The company closed an over-subscribed private placement of $1.35 million last August.
