Yandal Resources Ltd (ASX: YRL) has reported further downhole fire assay results from the RC and DD drilling at multiple prospects within the Gordons gold project in Kalgoorlie-Boulder Region of Western Australia.
YRL said that the RC drilling returned shallow high-grades including 1m @ 52.81g/t Au from 35m; while the diamond core drilling returned high-grades including 1.68m @ 11.94g/t Au within 4m @ 6.65g/t Au from 60.32m.
The company noted that all three diamond core holes intersected a number of sub-parallel to core axis structures and quartz veins which indicate the potential for high-grade mineralisation to crosscut the geological sequence. The company said that the assays from the third DD hole are pending ahead of RC drilling to specifically target these structures.
Drilling at Gordons gold project
The company had recently completed a total of 11 holes for 1,729.80m, including eight reverse circulation (RC) holes for 786m and three diamond core (DD) holes for 943.80m at the Gordons gold project.
The drill holes were completed at the Gordons Dam, Malone, and Star of Gordon prospects as part of ongoing programs to test both advanced and early-stage gold targets.
YRL said that three angled RC holes (YRLRC0483, YRLRC0484, and YRLRC0485) and three-hole HQ/NQ2 triple tube diamond core (YRLDD005, YRLDD006, and YRLDD007) drill program was completed at Gordons Dam Prospect; three angled RC holes (YRLRC0486, YRLRC0487, and YRLRC0488) were completed at Malone Prospect; and two angled RC holes (YRLRC0489, and YRLRC0490) were completed at Star of Gordon Prospect.
High-grade drill results
The company has now reported encouraging new downhole fire assay results from the RC and DD drilling at these three prospects.
Gordons Dam prospect
The company reported that significant intercepts were returned from the RC holes and results continue to demonstrate potential to develop a shallow open pit mine. Highlights included 1m @ 3.17g/t within 4m @ 0.89g/t Au from 33m and 3m @ 0.12g/t Au at end-of-hole (YRLRC0483); 1m @ 52.81g/t within 51m @ 1.41g/t Au from 35m (YRLRC0484); 1m @ 0.57g/t Au within 8m @ 0.31g/t Au from 51m; and 2m @ 0.61g/t Au within 31m @ 0.20g/t Au (YRLRC0485).
The diamond hole YRLDD006 intersected 4.00m @ 6.65g/t Au from 59.00m including 1.68m @ 11.94g/t Au from 60.32m.
Malone prospect
YRL said that important hits from Malone prospect included 1m @ 1.01g/t Au and 1m @ 2.51g/t Au within 5m @ 0.97g/t Au from 64m (YRLRC0486); and 2m @ 0.50g/t Au within 7m @ 0.25g/t Au from 68m (YRLRC0488).
Star of Gordon prospect
Yandal said that significant intercepts returned from Star of Gordon included 2m @ 0.54g/t Au from 48m within 5m @ 0.42g/t Au from 46m (YRLRC0490). The company said that follow-up RC drilling is planned as part of the March Quarter 20,000m program.
Further work
The company announced that the key exploration activities planned during the March Quarter at the Gordons project include sampling and receipt of assay from the remainder of diamond hole YRLDD006 and YRLDD007 and implementing a follow-up RC program; completion of 20,000m combined of AC and RC drilling across the Gordons project and compile a maiden MRE for Gordons Dam; and commencement of pit optimisation and technical activities for mining approvals at Gordons Dam.
Management comments
Yandal Resources’ Managing Director Lorry Hughes said: “We continue to be encouraged by the exploration results to date from Gordons Dam and once the final diamond hole is processed, we will formulate a new interpretation for the high grade structures to be immediately targeted with RC drilling.
It is clear from the diamond drill core that the holes were oriented in the correct direction to intersect the geological sequence at a perpendicular angle, however, upon receipt of all available data this is likely to be changed to specifically target high grade mineralisation.
RC and AC drilling is set to resume at Gordons Dam and other priority prospects in the Kalgoorlie region on the 20th January”.
