Yandal Resources Ltd (ASX:YRL) will serve up 6,000 metres of drilling next month after receiving encouraging aircore drilling results from the Ironstone Well and Barwidgee gold projects in WA’s Yandal Greenstone Belt.
The reconnaissance program of 41 aircore holes for 2,774 metres was completed at the Flushing Meadows, Flinders Park, Quarter Moon, Oblique and Rosewall prospects.
At Flushing Meadows, the strike length was doubled to more than 2 kilometres with mineralisation remaining open to the north and at depth.
Significant gold mineralisation was also returned at Rosewall, including 10 metres at 2.41 g/t gold from surface.
Yandal Resources’ managing director Lorry Hughes said: “To extend the Flushing Meadows mineralisation strike length from 1 to 2 kilometres is an excellent result and indicates an oxide gold system that is open to the north and at depth.
“Additional results are due soon from the February resource drilling and re-sampling program at Flushing Meadows.
“These will assist us to complete the detailed design of new strike extension holes and additional holes to test the system at depth.”
The aircore program returned significant mineralisation from all prospects with “outstanding” results from Flushing Meadows, Flinders Park and Rosewall.
Fourteen holes were completed at Flushing Meadows for 1,386 metres and shallow oxide mineralisation was intersected in multiple holes, demonstrating that mineralisation remains open.
These results have prompted the company to begin the next phase of exploration.
Next phase of exploration
A 6,000-metre resource definition and confirmation reverse circulation (RC) program is being designed to test priority targets with 5,000 metres of this at the new northwest extension zone at Flushing Meadows.
This is scheduled to begin in April with the aim of compiling an initial JORC-compliant resource estimate for the prospect.
It will also test a number of targets further northwest along strike and in adjacent positions where anomalous gold has been reported in historical drilling.
The combined Flushing Meadows RC program is expected to comprise up to 5,500 metres.
Hughes said: “The mineralisation is very shallow so if we can confirm continuity with resource-style infill RC drilling, we should be able to demonstrate economic potential.”
Strong hits at Flinders Park
At Flinders Park prospect, also within the Barwidgee Shear Zone, eight aircore holes for 702 metres were completed.
Best results were 3 metres at 4.18 g/t from 37 metres in a bottom of hole sample; 4 metres at 0.97 g/t from 39 metres and 1-metre at 1.34 g/t from 46 metres.
A follow-up RC drill program to test for extensions to the Flinders Park mineralisation at depth is at the advanced planning stage.
Rosewall also encourages
There were 12 holes for 292 completed at Rosewall with best results of 10 metres at 2.41 g/t from 0 metres and 18 metres at 1.00 g/t from 6 metres.
Hughes added: “At Flinders Park and Rosewall prospects we successfully confirmed the location of mineralisation reported in earlier drilling so we will also further test these prospects with RC drilling as part of the April program.”
