Heritage Gold NZ Ltd (HTM) – Given An Unexpected Opportunity to Potentially Achieve Gold Production
- Heritage is a North Island NZ gold exploration company that was established in 1984 by Peter Atkinson and has the opportunity to toll treat ore through Newmont’s Waihi Gold (or Martha Mine), following the discovery of the Favona mineralisation and extension of Waihi’s life to ~2015 at 300,000t and >100,000ozpa.
- Newmont’s expected >1moz Favona gold mineralisation was discovered using geophysics, following up the relationship between vent breccias and gold mineralisation that HTM had proven at its Onemana project. HTM are applying similar geophysical techniques (and the same consultant) at its Waihi North project, located almost on the edge of the Waihi open-cut and extending through to the old Golden Cross mine.
- Heritage initially uses an inverted aeromag technique to target potential gold mines in its main project areas of Waihi North and Karangahake, before following up with geophysics. The inverted aeromag technique highlights epithermal alteration that can be shown as identifying the historical gold mining districts (adjacent to HTM’s projects) of Waihi and Golden Cross.
- Apart from Onemana, all HTM’s exploration projects are located within about a 10km radius of the Waihi gold mine. At Karangahake, Heritage are using the inverted aeromag technique and a recently completed 3-D perspective of the old workings, development and stopes, so as to prioritise where to explore with a view to attaining early cashflow.
- At adjacent Rahu, HTM have identified a hidden potentially mineralised system through applying geophysics, that can now be drilled with a focus on attaining early cashflow by potentially using the spare capacity in Waihi’s 1.3mtpa mill.
