Proposed Work Program
US Copper Corp has a drilling contract with Timberline Drilling Inc. to drill a minimum of 6,000 feet at the Superior and Engels deposits. Drilling is scheduled to start in the first half of 2021 and will include up to seven holes at the Superior and Engels deposits.
At Superior, the Company is twinning four strategic historical drill holes, all located within the defined inferred resource, in order to: 1) verify historic copper assays; 2) intersect and confirm high grade copper-silver vein and breccia zones; and 3) assay for a full geochemical suite of elements (includes gold & silver), which has never been done. Placer-Amex did not analyze individual drill core samples for silver and gold.
At Engels, three inclined drill holes are designed to test a historic copper-gold “resource envelope” that Placer-Amex estimated contains a potential 19 million tons of mineralized material with a grade of 0.63% Cu (non-compliant; historic estimate1). The historic mineral resource envelope was outlined using underground drill hole and mine assay data, defining a halo of disseminated, breccia and vein style copper mineralization.
- 1. Sufficient work has not been done to classify this resource estimate as current mineral resources and so they are considered historical estimates. The Company is not treating the historical estimate as current mineral resources.
