Yandal Resources Ltd (ASX: YRL) announced that significant high-grade gold mineralisation including 8m @ 24.30g/t Au from 9m was intersected at the Sims Find prospect within its Barwidgee gold project in Western Australia.
Best assay results from shallow RC drilling at the Sims Find prospect included 8m @ 24.30g/t Au from 9m including 1m @ 129.00g/t Au from 12m; 3m @ 20.85g/t Au from 30m including 1m @ 62.25g/t Au from 30m; and 5m @ 3.33g/t Au from 22m including 1m @ 8.15g/t Au from 23m.
The company reported that the mineralisation is currently defined over 400m of strike and is open in all directions. YRL said that air-core and RC drilling is in the advanced planning stage to test multiple large scale exploration targets as part of the Company’s 100,000m program for 2021.
Drilling at Sims Find prospect
During the December Quarter 2020, the company had completed a total of 39 angled reverse circulation holes for 2,458m at downhole depths between 18-102m at the Sims Find prospect. The holes were designed to confirm and extend historic mineralisation in the vicinity of the historic Sims Find and Lady Lila shallow underground workings that were mined briefly in the 1930’s.
YRL reported that significant mineralisation has been confirmed occurring in multiple parallel quartz veins, sulphides, and shears within a large coarse grained intrusive dolerite rock unit.
Multiple high-grades
Yandal announced that most holes returned significant mineralisation which is interpreted to dip shallowly toward the south west, and strike in a north west direction.
Important hits included 8m @ 24.30g/t Au from 9m including 1m @ 129.00g/t Au from 12m (YRLRC457); 3m @ 20.85g/t Au from 30m including 1m @ 62.25g/t Au from 30m (YRLRC447); 5m @ 6.53g/t Au from 17m including 1m @ 30.40g/t Au from 17m (YRLRC445); 2m @ 12.27g/t Au from 37m including 1m @ 24.03g/t Au from 37m (YRLRC432); 2m @ 9.06g/t Au from 48m including 1m @ 17.90g/t Au from 48m (YRLRC450); 7m @ 3.50g/t Au from 23m including 1m @ 12.05g/t Au from 26m (YRLRC433); and 5m @ 3.33g/t Au from 22m including 1m @ 8.15g/t Au from 23m (YRLRC440).
Highly prospective target zone
The company said that the mineralisation is currently defined over 400m of strike and demonstrate the potential of a >10km long priority target zone.
YRL said that there are numerous historic reconnaissance drill holes with significant gold along parts of a large (4km by 2km) intrusive granitoid contact to the south. The company noted that almost all of the historic drilling is of an early stage or reconnaissance nature and anomalous intercepts have received very little or no follow-up exploration.
The Company said that it is at an advanced stage of reviewing the available geophysical, geochemical, and geology datasets in light of the new results and is generating exploration drilling plans to implement in the March and June Quarters 2021.
Further work
The company announced the key exploration activities planned during the March and June Quarters. This includes receiving and interpreting 1m RC assays from Flinders Park, Mt McClure, Rosewall, Oblique, and Quarter Moon and commence follow-up RC programs; commencing reconnaissance drilling between Flinders Park and Flushing Meadows and along strike from Sims Find; completing 20,000m combined of AC and RC drilling across the Gordons project and assess the potential to compile a maiden MRE for Gordons Dam; and commencing pit optimisation and technical activities for mining approvals at Gordons Dam.
Management statements
Yandal Resources’ Managing Director Lorry Hughes said: “It is really quite astounding that we have been able to generate these high-grade intercepts and improve the prospectivity at Sims Find and the immediate adjacent areas with our first drill program. The area has seen fractured ownership in the past which has hampered effective exploration.
We have an incredible opportunity to take a big picture view with our consolidated ownership of the area and leverage off a number of highly anomalous historic intercepts to explore for major deposits along strike and at depth”.
