EDM Resources Inc (TSX-V:EDM, OTC:SWNLF) has reported gold assay results from zinc and lead concentrates at its Scotia Mine in Nova Scotia, Canada, which returned grades of 2.93 grams per tonne (g/t) and 142 g/t, respectively.
The lead concentrate composite sample graded 142 g/t gold, with repeat assays of 157 g/t and 95 g/t. The zinc concentrate composite sample returned 2.93 g/t gold, with repeat assays of 3.64 g/t and 1.46 g/t.
The company said it collected a 4.68-kilogram composite sample from an estimated 2.9 cubic metre lead concentrate pile and a 5.2-kilogram composite sample from a 19.5 cubic metre zinc concentrate pile.
The material was produced in approximately 2009 from mineralization extracted from the main pit and processed through conventional crushing, grinding, and flotation circuits.
"Recently, we examined a limited amount of historical core from underneath the main zinc and lead carbonateous zone in the Meguma Terrane formation because we observed strong gold and silver grades in an independent laboratory assay report,” EDM Resources CEO Mark Haywood said.
“The assays were from when Scotia Mine was last in operation in 2009. In conducting a detailed element assay sweep of some of the large concentrate piles in the Load Out Facility at the mill, we were excited to observe very high initial gold grades of 2.93 g/t and 142 g/t.”
The samples were analyzed at AGAT Laboratories in Calgary, Alberta, and Thunder Bay, Ontario.
Following initial results, EDM requested additional multi-element and gold analyses, including new splits and pulp fractions of archived sample material.
“As a result of the positive confirmation assaying, the company is planning to conduct additional assaying of the concentrates and a review the gold potential at the Scotia Mine using professional geological services,” Haywood added.
According to the company’s 2021 Pre-Feasibility Study, the Scotia Mine is expected to produce 417,144 tonnes of zinc concentrate and 194,004 tons of lead concentrate over its life.
