What was the major discovery announced by Havilah Resources (ASX: HAV)?

Havilah Resources intersected significant stratabound copper mineralisation on the eastern limb of the Birksgate anticline. The results confirm that copper, gold, and molybdenum mineralisation is widespread, extending approximately 6 km from the original discovery made in 2014.

Why is the 6 km distance mentioned in the Birksgate results significant?

The 6 km distance between the new drillholes and the original discovery proves that the mineralised stratigraphic package is distributed over a very large area. It suggests a potentially massive untested target area with a strike length exceeding 50 km based on aeromagnetic data.

What were the standout drill numbers for Havilah Resources (ASX: HAV)?

Drillhole BKRC013 returned 26 metres of 0.14% copper starting from 120 metres depth. Within that interval, a higher-grade section showed 3 metres at 0.38% copper, accompanied by elevated gold and molybdenum values.

How does the Birksgate prospect relate to Havilah’s Kalkaroo deposit?

The mineralised host unit at Birksgate is interpreted to be the lateral equivalent of the K2 prospective horizon at the Kalkaroo copper-gold deposit. Both sites share similar geochemical signatures, featuring copper associated with gold and molybdenum.

What is a "skarn" deposit, and why does Havilah (ASX: HAV) mention it?

Skarns are metal deposits formed when hydrothermal fluids interact with carbonate-rich rocks. Havilah identifies Birksgate as a skarn prospect where sulphide minerals have replaced carbonate layers, a geological model that helps them predict where higher-grade "structurally favourable" zones might be hidden.

What did the drilling find regarding manganese and iron?

Drillholes BKRC010 and BKRC011 targeted the core of the anticline and found high manganese (up to 8.8% Mn) and elevated iron. Geologists believe these high manganese levels could represent the outer or "distal" parts of a larger regional mineralising system.

Havilah Resources finds widespread copper at Birksgate

Havilah Resources has reported significant stratabound copper mineralisation following an 11-hole reverse circulation drilling program at its Birksgate prospect in South Australia.

The program successfully intersected mineralisation on the eastern limb of the Birksgate anticline, approximately 6 km from the project's original discovery site.

"This indicates a potentially large untested target area for stratabound copper mineralisation, including more than 50 km strike length of the target prospective horizon based on our interpretation of the aeromagnetic data," said Havilah Resources Technical Director Dr Chris Giles.

Standout drillhole BKRC013 returned 26 metres of 0.14% copper from 120 metres, including a higher-grade interval of 3 metres at 0.38% copper.

The copper mineralisation is associated with elevated gold and molybdenum, confirming a geochemical signature consistent with the company's nearby Kalkaroo deposit.

Drilling also encountered manganese-rich footwall rocks in the core of the anticline, which the company suggests may indicate a distal skarn mineralising system.

Future exploration will focus on locating favourable structures where disseminated mineralisation could potentially reach higher grades across the 8 $km^2$ prospect area.

At the time of reporting, Havilah Resources' share price was $0.62.
