ASX Announcement 14 January 2021
Further high-grades - Gordons Dam gold prospect
-
RC drilling returned shallow high-grades including; ➢ 1m @ 52.81g/t Au from 35m (YRLRC0484)
-
Diamond core drilling results received from two of three holes completed to interpret structural controls to known mineralisation returned high-grades including; ➢ 1.68m @ 11.94g/t Au within 4m @ 6.65g/t Au from 60.32m (YRLDD006)
-
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 – assays from YRLDD007 are pending ahead of RC drilling to specifically target these structures.

Figure 1 – Gordons Dam diamond drill core hole YRLDD007 from 68.30m – 71.70m downhole showing a fractured and brecciated quartz vein interspersed with coarse pyrite and minor chalcopyrite – assay results pending. Note the low angle to core axis contact with a granite porphyry unit at approximately 71.50m.
Yandal Resources’ Managing Director; Mr Lorry Hughes commented:
“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 20[th] January”.

A total of 11 holes for 1,729.80m (eight RC holes for 786m and three DD holes for 943.80m) 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.
Gordons Dam Prospect
A total of three angled RC holes for 306m were completed in areas adjacent to known mineralisation within shallow palaeochannel sediments, porphyry and mafic rock types to a maximum downhole depth of 132m (Figures 2 – 5 & Tables 1 & 2). A number of significant intercepts were returned and results continue to demonstrate potential to develop a shallow open pit mine. Highlights include;

A three hole HQ/NQ2 triple tube diamond core drill program was completed in November with a total of 943.80m drilled to a maximum downhole depth of 325.40m. The holes have been geologically and structurally logged and sampling is partially complete. Results from this program will be used to improve the geological interpretation of the high grade zones or structures which are planned to be confirmed with RC drill testing in February.

Figure 4 – Gordons Dam prospect cross section plan (A – A’, refer Figure 3). over interpreted geology showing the location of new diamond drill holes with assays received and some earlier Yandal drilling located on section.
The results thus far indicate the potential for high grade structures with quartz veining oriented sub-parallel to the predominant direction of RC and diamond drilling. Diamond hole YRLDD006 intersected 4.00m @ 6.65g/t Au from 59.00m including 1.68m @ 11.94g/t Au from 60.32m within sheared basalt and up to 20% quartz oriented at 10-30 degrees to core axis.
Diamond hole YRLDD007 located approximately 90m to the southeast of YRLDD006 intersected a fractured and brecciated quartz vein interspersed with coarse pyrite and minor chalcopyrite within a granite porphyry rock unit from 68.30 – 71.70m downhole – assays pending (Figure 1, 3 & 5). If the vein is mineralised it could suggest structures are present that cross cut both the basaltic rock sequence and the intrusive granite porphyry rocks.
Understanding the geology and the orientation of important structures in the vicinity of known high-grade mineralisation will improve exploration targeting for the entire 1.5km of bedrock mineralisation that has currently been defined at the prospect (Figure 5).

Substantial ongoing follow-up RC and AC drilling programs to expand the known mineralisation are set to commence on 20 January with over 20,000m planned for completion in the March Quarter 2021 at Gordons Dam and a number of priority prospects (Figure 2).
It is currently planned to compile geological interpretations and wireframing for inclusion in a maiden Mineral Resource Estimate for the Gordons Dam prospect in order to progress feasibility studies and mining approval activities during the March Quarter 2021.
Malone Prospect
A total of three angled RC holes for 270m were completed to test for new shallow oxide and primary gold mineralisation as an immediate follow-up to significant mineralisation intersected in a 2020 AC program[1] including;
-
➢ 1m @ 0.46g/t within 10m @ 0.18g/t Au from 59m (YRLAC0395); and
-
➢ 1m @ 5.44g/t or 2m @ 4.73g/t Au within 9m @ 1.39g/t Au from 58m (YRLAC0396).
The small program successfully confirmed mineralisation within oxidised material in all three holes, highlights include;
-
➢ 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).
The new mineralisation is open in all directions and in an area that has had limited historical drilling. Followup RC drilling is at the advanced planning stage to be included in the March Quarter 20,000m program (Figures 2 & 5).
Star of Gordon Prospect
A total of two angled RC holes for 210m were completed to test for new shallow oxide and primary gold mineralisation in the vicinity of historic workings (Figure 2 & Table 1). A number of significant intercepts were returned including;
- ➢ 2m @ 0.54g/t Au from 48m within 5m @ 0.42g/t Au from 46m (YRLRC0490)
Follow-up RC drilling is planned as part of the March Quarter 20,000m program.
Next Steps
Key exploration activities planned during the March Quarter at the Gordons project include;
-
Sample and receive assay from the remainder of diamond hole YRLDD006 and YRLDD007 and implement a follow-up RC program;
-
Complete 20,000m combined of AC and RC drilling across the Gordons project and compile a maiden MRE for Gordons Dam;
-
Commence pit optimisation and technical activities for mining approvals at Gordons Dam.
