Summary:
The zinc-lead mineralization of the Lone Mountain Property is constrained to the Devils Gate limestone/dolostone. There are two distinct types of mineralization found on the Property. The first type of mineralization is easily distinguishable from the grey host dolostone by its pink, red, yellow, orange to brown colour and produces both high and low grade assay results. This mineralization occurs in the brecciated dolostone of the Devils Gate Formation and is composed mainly of smithsonite and hemimorphite as fine grained aggregates or crystalline components filling voids. The breccia is often clast supported but the mineralization can be found within the colourful fine-grained matrix of the breccia or in dolostone clasts. Lesser amounts of lead occur with this type of mineralization however no significant lead minerals were detected in recent mineralogical work. The second type of mineralization is more difficult to define as there appears to be no significant colour or textural differences to distinguish the mineralization from the fine to medium grained host dolostone. The mineralization is grey to grey-white and produces both high grade and low-grade assay results. White crystalline and fine-grained barite and carbonate (mostly calcite) veins are ubiquitous across the Property.
The mineralization is predominately hemimorphite (Zn silicate-hydroxide), smithsonite (Zn carbonate) and Zn-bearing dolomite. Within the Extension Shaft area of the Lone Mountain Mine, t ........
Summary:
The current drilling program is part of a work program designed to evaluate the potential of the Project to host near surface zinc-lead Mineral Resources that could potentially be mined using low cost open pit mining techniques. The majority of the drill holes reported to-date from the Mountain View Mine Property and the Discovery Zone area of the Project have intersected near surface zinc-lead mineralization that is now known to extend from surface to a depth of approximately 250 meters beyond which it remains open to further expansion.
