High Impact Drilling Follow-Up Programme Set To Resume
Yandal Resources Ltd (ASX: YRL) has received positive new downhole fire assay results from reverse circulation (RC) drilling at the Gordons Dam gold prospect within the Gordons gold project located in the highly prospective Kalgoorlie-Boulder Region of Western Australia.
A total of 22 holes for 2,531m were completed in March and drilled at four different directions (azimuths) to test a number of geological interpretations prior to design of expansion diamond and RC drilling at depth.
Managing Director; Lorry Hughes, said preparation to complete a follow-up diamond hole to target mineralisation at ~250m depth has commenced.
“The new high-grade primary mineralisation is interpreted to strike in a NNW – SSE direction sub-parallel to the known porphyry intrusion and has a sub-vertical dip,”Mr Hughes said.
“Combining the geological information from the 2020 diamond core drilling program, specifically the orientation of high-grade quartz veins and structures, a high- grade zone can be traced for at least 200m in strike length and is open.
“The zone is interpreted to be one of several similarly oriented zones confined within a broader structural zone that is related to a moderately east dipping ‘main’ zone that has been intruded by the porphyry. The porphyry contains gold mineralisation with disseminated sulphides and quartz veins and it has displaced gold bearing quartz veins and structures.
“Exploration will continue to target large extensions of the intrusion as it is believed it has intruded into a major gold bearing structure.
“Further drilling and data analysis is required to ascertain the main controlling features on the mineralisation and an expert structural study is planned during May/June to aid the definition of high-impact mineralisation targets going forward.”
Four metre composite assay results are pending from the top 28m of each hole and from holes that were not completed to planned depth due to adverse drilling conditions. The sample intervals from 28m to the end of each hole were submitted for analyses as a priority and numerous significant intervals were returned including:
- 2m @ 10.83g/t Au from 118m to end-of-hole including 1m @ 20.68g/t from 118m;
- 2m @ 11.10 g/t Au from 73m including 1m @ 20.41 g/t from 73m;
- 6m @ 3.39 g/t Au from 116m including 1m @ 9.25 g/t from 119m;
- 19m @ 2.86g/t Au from 36m including 1m @ 38.07g/t from 37m;
- 9m @ 3.78 g/t Au from 31m including 1m @ 23.01 g/t from 32m; and
- 5m @ 5.85 g/t Au from 38m including 1m @ 26.28 g/t from 38m.
