THE DRILL SERGEANT: The results are back in from Orrex Resources’ first reverse circulation (RC) drilling program at the Lakeside prospect, on its Golden Mile South project in Western Australia.
The campaign consisted of eleven holes, four of which intersected gold mineralisation, for a total of 1,300m of reverse circulation drilling.
Orrex said the holes delineated a mineralised and altered shear zone consistent with those hosting major gold deposits in the Eastern Goldfields.
Prior to this program there had only ever been five RC holes testing bedrock drilled on the entire 100 square kilometre project area.
The company said it was excited about the results from this initial drilling and that it was also an encouraging outcome for both the Lakeside prospect and for the entire Golden Mile South project.
Orrex considers the results to have positive implications for its other targets at Golden Mile South targets.
It will now weigh up the benefits of infill drilling at the targets established at greater Lakeside prior to commencing any further RC testing at the Lakeside prospect.
The company’s thinking is that it may be more beneficial to work up the other targets at Lakeside with the intention to carry out a more comprehensive RC program on the greater Lakeside targets at one time.
Gold mineralisation was intersected in four drill holes along the central line of drilling within a 30 metre wide zone of alteration.
The best mineralisation was intersected in one hole where three, 6m to 14m wide, zones of gold mineralisation averaged between 0.7 grams per tonne and 1.59 grams per tonne gold, including 3m at 2.83 grams per tonne, from 30m, and 3m at 2.47grams per tonne gold from 54m.
Orrex said the RC program has given it a better understanding of the structural controls and style of mineralisation at Lakeside.
Because the campaign was focused to the north and south of the central line and was drilled down dip, Orrex said it is unable to determine the strike length of the structure at his time.
“We are pleased with the results of this inaugural RC program, Orrex Resources managing director Sonja Felderhof said in the company’s announcement to the Australian Securities Exchange.
“Hitting gold in bedrock on our first fresh rock program is exciting and highly encouraging not only for the Lakeside prospect but for the rest of the Golden Mile South project.
“The results validate our belief that the project is highly prospective for deposits similar to those in the region.
“The historic approach to exploration on the project area was focussed on discovering near surface alluvial deposits and consequently missed the opportunity to test the surface geochemical anomalies into bedrock.
“We will continue our evaluation on the Lakeside prospect and our other targets in the area to determine the best program going forward at Lakeside.
“We look forward to see what further work will realise at the Lakeside prospect, and other targets in the Golden Mile South project.”
