Rockcliff Metals (CSE: RCLF) announced that it has updated the mineral resource estimate of its Tower property, located in the Canadian province of Manitoba.

In a press release, Rockcliff explained that it filed a National Instrument 43-101-Standards of Disclosure for Mineral Projects (NI 43-101) technical report related to the updated estimate prepared by P&E Mining Consultants.

Located near the central town of Wabowden and 130 kilometres from the Rockliff-leased Bucko Mill, the Tower project occupies 9,530 hectares and hosts a high-grade copper deposit

The report shows that indicated copper grade increased by 26% (4.69% from 3.73%), indicated gold grade increased by 55% (0.85g/t from 0.55 g/t); indicated zinc grade increased by 26% (1.32% from 1.05%); indicated silver grade increased by 37% (23.7g/t from 17.3g/t); indicated contained copper metal content increased by 19% (106.1Mlbs from 89.2Mlbs), but indicated tonnes decreased by 5% (1.03Mt from 1.08Mt).

According to the Sudbury-based miner, this mineral resource estimate considered drilling information available up to December 21, 2019 and was evaluated using a geostatistical block modelling approach constrained by polymetallic mineralization wireframes using Geovia GEMS modelling software. 

“The significant increase in the copper grade to one of the highest-grade deposits in the camp at 4.69% Cu bodes well for the PEA analysis,” Alistair Ross, Rockclif president and CEO, said.
