Rockcliff Metals (CSE: RCLF) announced that it has officially 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 some 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 utilizing Geovia GEMS modelling software.
“We continue to be pleasantly surprised by the Tower property drilling results,” Alistair Ross, Rockclif president and CEO, said in the media brief. “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.”
