Great Boulder Resources announced AC drilling is underway at the Whiteheads project north of Kalgoorlie in Western Australia. HIGHLIGHTS: A 5,000m air-core (AC) drilling program has commenced at the Whiteheads Project. Five regional targets will be tested, including prospects on the Arsenal Trend.

Assays received from the regional AC program completed in Sep-Oct 2021 returned several encouraging anomalous intersections similar to the early-stage drilling at Blue Poles, where thick zones of gold mineralisation were discovered beneath anomalous bottom-of-hole assays in the initial AC coverage. RC drilling results from Side Well are due imminently and diamond drilling is scheduled to recommence next month. Approximately 5,000m of drilling is planned to continue testing five regional targets, including Blue Poles South, Tektite and Highbury on the Arsenal Trend, as well as further drilling at Jubilee North and the first drill program at the Eclipse prospect.

Drilling is expected to take approximately three weeks. Once this program is completed a diamond rig is scheduled to commence drilling at the Mulga Bill prospect at Side Well in mid-February. 2021 AC Results: 122 AC holes were drilled at Whiteheads for 5,166m in September and October 2021 testing a range of regional targets including some that had not previously been drilled.

These included: 8 holes (439m) at Gunners on the Arsenal Trend, 23 holes (1,127m) at Tektite, south of Blue Poles on the Arsenal Trend, 8 holes (518m) at Highbury, on the Arsenal Trend southwest of Tektite, 6 holes (226m) on a single fence of drilling at Reception Hill, 57 holes (1,919m) along strike to the northwest and southeast of Seven Leaders, 20 holes (937m) at Jubilee North. All assays have now been received. The program generated a number of anomalous intersections, including 1m @ 2.55g/t Au from 41m in 21WHAC110 at Tektite, 4m @ 0.61g/t Au from 80m in 21WHAC128 at Jubilee North and 12m @ 0.23g/t Au from 67m in WHAC174 at Seven Leaders.

Importantly, the Tektite and Highbury results continue to add to the potential of the Arsenal Trend south of Blue Poles. Air-core results of this type are encouraging in comparison to early-stage drilling at Blue Poles, where thick zones of gold mineralisation were discovered beneath anomalous bottom-of-hole assays in the initial AC coverage.
