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

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.
