Ann: Outstanding High Grade Au and Cu Mineralisation Intersected, page-72

The fracture/fill hydrothermally brecciated structures that are punching through the permeable horizons of the host rock sequence (volcanic/sediments) are related to the intrusion of the late stage diorite. Octagonal intersecting those structures + LEX the primary mineralisation in the diorite is such a proof of concept for a porphyry style model (and I use this as a generic term - since you can chase them out to the low/high sulphidation and skarn styles), that I really shouldn't need to say anymore. If need more evidence, look at the alteration mineralisation as you move from low temperature to high temperature, proximal to distal intrusion, and see how it maps a temperature gradient, from epidote/chlorite (propyitic) to magnetite - pyrite (proximal, and would like to see the K values as proof of potassic alt). Remember that the Archean sequence has been tilted, even post late stage magmatism, so what was once 'above' the intrusion might be located East/West now. Mineralisation styles can also get reworked, evidence is the trace chalcopyrite in some orogenic gold camps in the Yilgarn, which suggests remobilised epithermal style. So my point is if you take a selected slice through a large (camp scale) mineralised system, you will be looking from a subjective place, whereas if you step back and look at a broader scale, like LEX is doing suggesting that the Lucky strike might be part of the same system (ie. fed by magmatic fluids from the Burns intrusion), your model will be more complete, and that WILL lead to greater chance of discovery, period. Look up the mineral systems approach to exploration if you want more clarification, something that both industrial and research based geoscientists actually agree on (at least until you get to smaller deposit scale targeting - were a field geologist makes his money)
