Yandal Resources Ltd (ASX:YRL) has started a new drilling program at Gordons Gold Project in WA’s North-Eastern Goldfields to follow-up shallow high grades of up to 8 metres at 7.33 g/t and 3 metres at 18.30 g/t.
An aircore program of 24 holes for about 1,440 metres is underway at Gordons Dam prospect, which is 36 kilometres northeast of Kalgoorlie-Boulder.
The program is expected to be completed by March 16 with initial results anticipated next month.
Reverse circulation (RC) drilling in December 2018 returned highly encouraging results and demonstrated palaeochannel-hosted gold mineralisation was more extensive than initially interpreted.
This drilling also returned significant primary mineralisation from within hematite altered porphyry and sheared mafic rocks at depth.
The aim of the new program is to further define the extent of significantly mineralised palaeochannel sediments and to drill deep enough to identify the primary rock types.
Yandal’s managing director and CEO Lorry Hughes said: “With gold trading at very attractive levels above $1,800/ounce and the clear prospectivity of our projects, I look forward to providing exciting information from exploration and mining development activities in the near-term.”
Aircore holes will be drilled vertically to a depth of about 60 metres on a nominal 50 by 100-metre grid at Gordons Dam, which is 22 kilometres north along strike from the Kanowna Belle mining centre.
Yandal expects that the results will enable it to generate further aircore and RC drilling targets.
The company can then begin to assess compilation of an initial JORC-compliant resource estimate.
Initial program at Mulgarrie North
An initial two-hole aircore program for 170 metres will also be undertaken at Mulgarrie North prospect where a supergene gold anomaly was defined by limited rotary air blast drilling by North Limited in 1994-5.
This prospect is 9 kilometres northwest from Gordons Dam and 3 kilometres northwest along strike from the Mulgarrie open pit gold mine owned by Norton Goldfields Ltd.
The program aims to confirm the supergene anomaly in the vicinity of an historical diamond hole which returned a narrow but encouraging intercept of 1-metre at 2.20 g/t from 117 metres downhole.
Geological mapping, rock chip and orientation soil sampling programs will also be carried out to define new targets along strike for drill testing in the near-term.
Work on new tenements
Two exploration tenements contiguous with the Gordons project and totaling 320 hectares were recently acquired from local prospectors.
This ground is just 1-kilometre north along strike from the operating Gordon-Sirdar underground gold mine owned by FMR Investments Pty Ltd.
A number of small gold mines from the early 1900s exist on these tenements and the company is compiling data from historical drilling and has started prospecting activities.
Hughes said upcoming catalysts for the company were:
- Aircore and RC assay results from the Flushing Meadows, Flinders Park, Oblique, Quarter Moon, Rosewall and Success prospects in the Yandal Belt are due in the coming weeks;
- Follow-up drilling of priority targets;
- JORC resource compilation activities at the most advanced prospects; and
- Aircore drilling results from the Gordons Dam and Mulgarrie North prospects.
The company has recently completed drilling at various prospects within the Ironstone Well, Barwidgee and Mt McClure projects in the Yandal Belt.
There were 208 samples submitted from the aircore program and 700 samples from the RC program.
An additional 229 individual 1-metre samples were also resampled from available historical aircore and RC residues.
These samples will be used as part of database verification activities for resource estimation.
