Blackham Resources confirms high-grade gold shoot at Williamson

Assays for the first 39 holes of the 55 hole drill program have been received.

Williamson - latest intercepts confirms the strike extension of a large mineralisation system, south from the pre-existing pit
Assays also confirm strike extension to the south

Blackham Resources Ltd (ASX:BLK) has confirmed, through drilling, a new high-grade gold shoot along strike from existing reserves at the Williamson Project in Western Australia.

Williamson is 18 kilometres south of the Wiluna gold plant and is a historical open pit mine that is currently filled with brine solution.

Through a deal with Salt Lake Potash Ltd (ASX:SO4), the pit is being dewatered so Blackham can mine it from August 2019.

Drilling from December 2018 to February 2019 comprised 46 reverse circulation (RC) holes and 9 diamond holes.

The program aimed to confirm resources and tested for extensions of the cutback pit design.

Highlights from the first 39 holes include:

• 29 metres at 3.06 g/t gold from 165 metres;
• 38 metres at 1.90 g/t gold from 139 metres; and
• 31 metres at 2.04 g/t gold from 131 metres.

Mineralisation significantly wider than modelled resource

The Williamson pit produced over 40,000 ounces at 2.0 g/t gold from two years of mining in 2005-6.

The current pit expansion contains a probable reserve of 0.95 million tonnes at 2.2 g/t gold for 68,000 ounces.

Blackham’s latest results confirm wider mineralisation zones than the current resource model both within and below the pit design.

A new resource will be estimated in the coming months.


Williamson Southern Extension likely to add to Ore Reserves

Infill drilling has now been completed over 1,000 metres of strike, with latest intersections within the new shoot defined.

The addition of these surface ounces should significantly improve the cutback economics of the southern half of the historical pit.
