Geologically, extensive zinc and lead sulphide mineralization is hosted within an east-west trending dolomitized reef structure which is part of the Presqu’ile barrier reef complex (Figure 1). Mineralization is by replacement and void-filling with sulphides deposited as colloform as well as coarse, vug-fill styles (Figure 2). On the project scale (Figure 3), concentrated sulphides are present in two deposit types: 1) Tabular: consisting of horizontal, locally continuous, mineralization, and 2) Prismatic: consisting of near vertical pinnacles of strong sulphide development. It is likely that the tabular deposits represent lateral fluid channel ways that connect the prismatic bodies. Both types of deposits are abundant in three parallel trends named the North Trend, Main Trend and the South Trend.
The current 2018 drill program is focussed on conversion of 50 million tonnes of unclassified near-surface historical resources to NI43-101 Indicated Resources as quickly as possible in areas amenable to open pit extraction. Exploration for additional new mineralization is being planned and will focus below the known mineralized horizons. And laterally where reef development is conducive to fluid flow and perhaps mineralization (Figure 3).
