Strong linear magnetic anomalies coincidental with the Magnetic Quartzite, which constitute the core of the copper-gold deposit. The resource of copper sulphide mineralogy commences at about 40 m depth, below the zone of oxidation and leaching, and is assumed to extend to at least 140 m depth. It includes the cementation zone of supergene concentration of metals. The width of cementation is estimated to vary up to 20 m from the experience of small mining in the region. No estimate of grade is attached to the ore of cementation zone.
Experience shows the highest level of supergene metals enrichment occurs in the zone of cementation.
The oxidised material needs to be leached to recover copper. Unless alkaline ammonia leaching is used, the gold may not be recovered economically by cyanide leaching from the acid saturated spent ore. Depending on a higher actual grade of gold, the option is open to use gravity or floatation techniques to recover gold. Copyright by G.L. Seymour M.Sc. 2001.
