Results from an infill and extension Aircore (AC) drilling program at Crest Minerals’ Mt Ida Project in Western Australia’s Eastern Goldfields have enhanced the project’s potential.

The program has refined and identified gold anomalism over 200 metres in length and the results provide encouragement ahead of a planned 6-hole reverse circulation (RC) drill program starting this month.

The AC program was completed at the Spotted Dog prospect to further test the strongest recorded gold-in-regolith anomalism identified by angled RAB drilling completed by Acacia Resources in 1999 and 2000, and to a lesser extent by GME Resources in 1995. Crest’s program has clearly identified three gold-mineralized trends.

All three Spotted Dog gold trends are sub-parallel and central to the large gold-in-auger soil anomaly generated by Newcrest Mining during the mid-1990s. The eastern-most zone of interest is the best defined and has the most consistent anomalism along strike. There is a main zone which has more than 200 metres of strike with gold-in-regolith anomalism. There is a possible westerly dip to the mineralized zone.

This eastern trend is the one highlighted by Acacia’s earlier work and has new significant intersection of 12 metres @ 1.62 grams/tonne gold, 4 metres @ 1.80 grams/tonne and 12 metres @ 0.395 grams/tonne, all of which are composite samples. Acacia returned intersections of 2 metres @ 1.10 grams/tonne and 8 metres @ 3.81 grams/tonne, including 1 metre @ 25 grams/tonne from this trend.

Crest believes the results are significant and warrant deeper RC testing below and down-dip of these intersections in the hypogene. A planned RC program of six angled holes should test the zone of interest. The RC program will be combined with other targets generated by planned auger and aircore drilling in coming months.

Crest’s managing director Angus Middleton says the gold prospectivity of the eastern trend is considered to be ‘good to very good’ for a narrow, but high-grade shear-hosted lode gold accumulation and further drill testing is planned. “The AC drilling program returned significant anomalous gold results which have given us further confidence ahead of our RC program.

“Our focus has been on the Spotted Dog tenement areas prior to an extensive auger program to assist in refining an intended AC drill program at Hoskins Find prospect – also part of our Mt Ida Project Area. The infill AC drilling has assisted more accurate targeting of RC drilling into the basement rocks. Additionally, we have combined all historical and current data to assist in finalizing the RC program, planned for the June quarter,” he says
