THIS!!! sounds very simalar... IMO

Hole TLDD0026 was a step-out hole that successfully intersected three horizons of massive sulphides, 45 metres along strike from the previous hole TLDD0021 (7.3 metres of massive sulphides from 286.2 metres down-hole).
What was particularly significant about TLDD0026 was that within its 19.9-metres thick zone of massive sulphides from 340.2 metres down-hole there was bornite - a copper mineral not previously encountered by Sandfire in any significant quantities at Doolgunna.
Bornite typically has a copper content of ~63% by mass, which means it has twice the copper content of the typical Monty copper host rock - chalcopyrite - that has ~35% by mass).

Cross-section through TLDD0026 NQ2 drill core showing bornite disseminated in the matrix of the sulphides (359.3 metres down-hole).
The joint venture then followed up with assaying of core from hole TLDD0026 that returned exceptional assay grades comprising:

• 7.3 metres grading 6.2% Cu and 2.8g/t Au from 325.6 metres down-hole (down-hole width, top of intercept is 275 metres vertically below surface); and
• 21.6 metres grading 34.4% Cu and 0.4g/t Au from 339.4 metres down-hole (down-hole width, top of intercept is 286 metres vertically below surface).
