Some concluding thoughts
1. Clearly there is evidence for considerable hydrothermal ac@vity at Kuruga. There is a deep porphyry
evident as well as extensive hydrothermal breccia present.
2. Gold in the lithocap is stratabound within a permeable tuffaceous horizon as well as within the
crackle and jigsaw margins of the breccia.
3. Copper in the lithocap is associated with a second (or third?) stage of breccia@on and is associated
with enargite-­‐pyrite cement.
4. No evidence has been seen to date to indicate that the breccias have a magma@c component. If
this is true, then they represent the catastrophic volume expansion of the hydrothermal fluid. If
this is true, there is no need for them to be located over the top of a porphyry-­‐style intrusion.
Instead, they can be lateral to the intrusive center.
5. The evidence for intense and pervasive K-­‐silicate altera@on in the deep drill demands a porphyry
center at depth, as would be expected. What is not know is whether it is mineralized as well. A drill
hole into the main part of the likely porphyry is warranted.
6. Judging from the depth of sulfide in drill core and in the nearby Lipa system, the sulfide in the
porphyry center is likely to begin around depths of 650 m RL, and extend to depth. This depth
approximately corresponds to the depth of extensive and not overprinted K silicate altera@on in
KUDD-­‐034.
