A high-grade zinc-polymetallic project gets some overdue rig attention as Rockcliff Copper TSXV:RCU returns to its Bur property in northern Manitoba’s Flin Flon-Snow Lake camp next month. Ten to 15 holes totalling around 3,000 metres will work on updating and expanding the VMS deposit along strike and at depth.
Using a zinc-equivalent cutoff of 5%, the historic, non-43-101 2007 estimate showed:
- - 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
Part of the company’s Snow Lake project, a package of properties totalling over 45,000 hectares, Bur sits about 22 kilometres by road from Hudbay Minerals’ (TSX:HBM) copper-zinc concentrator. Rockcliff’s 100% earn-in on Bur calls for $3 million in spending over four years.
Earlier this month the company announced initial geophysical results from its Laguna property, site of a former mine that produced 60,000 ounces of gold averaging 18.7 g/t during intermittent production from a single vein. With very low frequency and induced polarization surveys still underway, an airborne magnetometer found “multiple, surface-exposed, high-grade gold-bearing quartz vein stockwork systems,” the company stated.
Last May Rockcliff announced plans for two other Snow Lake gold properties as well as Laguna. The previous month the company reported drilling had encountered a new VMS zone with copper-zinc-gold-silver results on the 51%-optioned Talbot property. A 2016 43-101 inferred resource for Talbot’s three zones totals 133.6 million pounds copper, 165,400 ounces gold, 107.4 million pounds zinc and 3.81 million ounces silver.
Rockcliff’s northern Manitoba package also includes the Rail deposit with a 43-101 copper-polymetallic resource, three zinc deposits with historic, non-43-101 estimates in addition to Bur, as well as the three gold properties. All sit within trucking distance of two Hudbay plants.
Late last month Rockcliff closed an oversubscribed private placement of $1.35 million.
