This is illustrated by mines such as the Lupin and Musselwhite in Canada and the Homestake in South Dakota USA. </B></div> <bR> <div> <B>Since the associated veins and BIFs are frequently relatively narrow high grade units, mining is typically done by an underground operation. This type of mining has the least impact on the land surface and the environment. </B></div> <bR> <div> <B>The IRON POT claim area has excellent road access and infrastructure. The claims are traversed by a main power transmission line and most of the mineral showings are road accessible. </B></div> <div> <B>This would facilitate a cost effective property exploration and diamond drilling program.</B></div> <div> <B>Further exploration for a sulphide facies iron formation gold deposit on the Iron Pot claims is definitely warranted. </B></div> <bR> <div> <B>It is possible that the Iron Pot (Sulphide Facies) BIF property could be included within an option agreement and exploration program conducted on the Scotch Creek (Oxide Facies) Iron formation Au-Ag-Cu property. </B></div> <bR> <div> <B>Rich River is in the process of researching the available data and prospecting near the newly discovered showings.
