Recent drill results from Rockliff Metals' (CSE: RCLF) wholly owned Tower property in central Manitoba have increased the strike length of the Tower deposit to 1,000 metres and hit mineralization at depths of 800 metres.
Based on the potential for additional mineralization, Rockcliff has commissioned an updated resource estimate for Tower, which will be incorporated into the preliminary economic assessment (PEA) underway for the property.
According to Rockcliff president and chief executive Alistair Ross, "the PEA results are anticipated to be known before the end of the year."
In a statement, the company reported assay results for 12 holes. Drill highlights include 4 metres of 1.77% copper, 0.05% zinc, 0.22 gram gold per tonne and 13.22 grams silver per tonne (2.04% copper-equivalent); 3 metres of 4.98% copper, 2.56% zinc, 0.44 gram gold and 23.1 grams silver (6.39% copper-equivalent); and 3 metres of 3.89% copper, 3% zinc, 0.37 gram gold and 15.84 grams silver (5.36% copper-equivalent).
The company is using the drill results to broaden its understanding of the geotechnical aspects of the Tower deposit, while additional drill data will be used to support the mining and geotechnical assumptions in the PEA.
One additional hole is currently being logged.
In addition, Rockcliff completed four holes at the TGR nickel-platinum group element (PGE) prospect, which did not return visible mineralization. The samples are now in the lab for nickel and PGE analysis. A compilation study is underway to determine the next exploration steps for the zone.
In April, the company published an updated resource estimate for Tower, with 1 million indicated tonnes at 4.69% copper, 1.32% zinc, 0.85 gram gold and 23.7 grams silver (5.74% copper-equivalent); and 367,000 inferred tonnes at 3.53% copper, 1.05% zinc, 0.57 gram gold and 18 grams silver (4.29% copper-equivalent).
In addition to Tower, Rockcliff holds a lease on a 1,000-tonne-per-day processing and tailings facility, 130 km away. The company also wholly owns the Rail property and a 49% stake in the Talbot project (where Hudbay Minerals [TSX: HBM; NYSE: HBM] owns 51%). Rail and Talbot are also within trucking distance of the mill, in the Snow Lake area.
