THE DRILL SERGEANT: Octagonal Resources has received results from a recently completed infill aircore drilling program carried out at the Burns prospect, located within the company’s Hogan’s project in Western Australia, which the company said have defined two zones of gold.
Octagonal considers the Burns prospect to be a priority exploration target area that it is advancing through infill and extensional aircore drilling with the objective to define targets for bedrock drill testing.
The aim of the recently completed aircore drilling program was to enable the company to better define distribution of gold in regolith (weathered Archaean bedrock) anomalism.
Drilling was carried out using an 80 metre by 320 metre spaced grid and consisted of 101 holes, totalling 5,689 metres.
This was the first of two phases of infill aircore drilling the company is to undertake and that has been designed to eventually test the area with a 40m by 160m spaced grid to allow for targeted bedrock drilling.
Assay results of note from this drilling program included:
– 6 metres at 0.61 grams per tonne gold from 78 metres;
– 8m at 1.22 g/t gold from 80m;
– 4m at 0.55 g/t gold from 71m;
– 7m at 0.73 g/t gold from 82m;
– 6m at 0.20 g/t gold from 20m;
– 4m at 0.38 g/t gold from 42 metres to the end of hole;
– 8m at 0.29 g/t gold from 20m; and
– 2m at 0.89 g/t gold from 83m.
These results follow others released by Octagonal in May, which intersected zones of gold anomalism during regional aircore drilling using a 160m by 640m spaced grid.
These results included:
– 23m at 0.5 g/t gold from 18m to the end of hole;
– 12m at 0.3 g/t gold from 68m to the end of hole;
– 3m at 0.9 g/t gold from 44m; and
– 2m at 0.6 g/t gold from 63m to the end of hole.
“The gold results already intersected at Burns prospect are wider, higher grade, and more broadly distributed that those that led to the discovery of the Salt Creek Deposit, even though the drill hole spacing is also wider,” Octagonal Resources said in an announcement to the ASX.
“These observations further support the potential of the Burns Prospect to host a significant gold deposit.”
The company said it was highly encouraged by the latest results and will continue infill and extensional aircore drilling with the objective of refining gold in regolith anomaly targets for 2012.
It has already secured a land aircore rig for the second phase of infill drilling during October using a 40m by 160m spaced grid.
A lake aircore rig has also been booked to test for gold in regolith anomalism extending under the salt lake.
The lake aircore drilling program will commence as soon as an appropriate drill rig becomes available.
