Maiden drilling at the company’s flagship project Kraaipan was completed in the last quarter last year, with encouraging gold assays achieved.

Two directors left the company, including its managing director and founder Geoff Pocock, citing personal reasons.

Another quarter of record results failed to excite Blackham Resources (ASX:BLK) investors today – shares dropping 14 per cent to 8.6c.
