I talked to the MD. He said they had started their drilling program, which in total will be 60,000m. The first part will be 20,000m focussed on a number of pegmatites and gold. He told me first news should be coming out mid July, so we can expect something this week or the next if there's no delays. Sample results will be due in August if all goes well.

I dont think there has been an official NR that explicitly states that the drilling program has started, but there's some older NR's that talk about it
