Multiple Zones Of Significant Gold Mineralisation Defined
Yandal Resources (ASX:YRL) has receives promising new one metre downhole fire assay results from Air-core (AC) and reverse circulation (RC) drilling at multiple prospects within the Gordons gold project located in the highly prospective Kalgoorlie-Boulder Region of Western Australia.
Managing Director; Lorry Hughes, said numerous significant intercepts were returned along strike from earlier RC drilling resulting in the interpreted strike length of primary mineralisation zones being extended to ~1.5km.
“The evidence is mounting for a substantial bedrock gold target beneath surficial cover at Gordons Dam, we have now doubled the length of the exploration target zone at depth,” Mr Hughes said.
“The results of recently completed diamond drilling will be critical to improve our understanding of the controls on mineralisation beneath and adjacent to the known palaeochannel mineralisation.
“Directly south east along strike from the palaeochannel area it is clear that there are multiple zones of mineralisation within porphyry and mafic rock types that warrant priority RC drilling, that work is now planned for the March Quarter next year.
“RC drilling recommenced on 9 December to test new targets at the Gordons Dam palaeochannel, Malone and Star of Gordon prospects prior to cessation of drilling activities for 2020 in mid-December.
“Drilling will resume at our priority prospects as soon as practicable in the new year upon assessment of all pending results due in between now and the end of January 2021”.
A total of 158 holes for 7,819m (10 RC holes for 562m and 148 AC holes for 7,257m) were completed at the Gordons Dam, Malone, Cleft, Porphyry, Star of Gordon, Dickens Custer, Mulgarrie South, Mulgarrie North and Holloways prospects to test both advanced and early stage gold targets.
A total of 81 angled AC holes for 3,672m were completed along strike from and in areas adjacent to known mineralisation within shallow palaeochannel sediments, porphyry and mafic rock types.
The AC drill holes were completed to blade refusal and as has been the case with earlier AC programs, multiple significant intercepts were returned from just above or at the end-of-hole. A number of these intercepts occur on adjacent lines ~120m apart, are interpreted to represent subparallel mineralisation zones and are open in most directions.
Highlights include:
1m @ 0.60g/t within 5m @ 0.25g/t Au from 44m and 4m @ 0.09g/t Au at end-of-hole;
1m @ 0.67g/t within 4m @ 0.21g/t Au from 61m and 2m @ 0.31g/t Au from 68m;
1m @ 0.50g/t Au from 42m at end-of-hole; and
3m @ 0.12g/t Au from 52m at end-of-hole,
The mineralisation in the southern half of the extended ~1.5km interpreted strike length appears to have split into multiple parallel zones with the orientation influenced by east-west crosscutting faults.
Substantial follow-up RC and AC drilling programmes are in the advanced planning stages to expand the known mineralisation with over 20,000m planned for completion in the March Quarter 2021.
Site access to a number of priority follow-up holes was prepared in November and RC drilling to test the highest priority targets is underway. The RC rig is planned to demobilise from site in mid-December for servicing and resume the program as soon as practicable in the new year.
