In addition to the above immediate drilling targets, the potential for epithermal gold discovery of the Vera Nancy – Twin Hills types within the north western group of Zamia Gold’s tenements (EPMs 14790, 14792 and 14793) is rated as very high. However the area poses certain challenges to exploration as it is mostly concealed by younger weathered rocks and sand. In the rare locations where exposed, the rocks are deeply weathered and leached of metals, including gold, frequently rendering surface geochemical techniques inconclusive. Zamia Gold will rely on modern geophysical techniques followed by drilling to probe beneath the leached zone (reportedly up to 90 metres).
The Nardoo Prospect (EPM 14792, “Mount Rolfe”) is a good example of where a small area of subdued outcrop has been located and sampled returning anomalous results in gold and silver (0.22 g/t for both elements). This compares favourably with the original surface geochemical signature of the nearby Twin Hills discoveries. An exploration programme for this area has been planned.
At the Matta Prospect (EPM 14792, “Mount Rolfe” ) there are 5 zones of epithermal or mesothermal alteration in the form of intense silicification, brecciation and quartz veining within the Mount Rolfe volcanic complex. The veins extend for a maximum of 475m along a north-west trend, coincident with aeromagnetic lineaments. Rock chip sampling by previous explorers returned highest values of only low gold values. Zamia Gold intends to drill test these veins well below the surface as rapid changes from low to very high abundances of gold is a characteristic of epithemal veining in the vertical dimension.
These are just 2 prospects in a belt of intrepreted epithermal mineralisation which Zamia Gold intends to prospect intensively.
