A new deep diamond hole was completed to 342m and intersected the target porphyry hosted and related mineralisation at the Gordons Dam prospect, additional holes to follow – assay results pending.
Yandal Resources’ Managing Director; Mr Lorry Hughes commented:
“Results from first pass drilling at the Star of Gordons prospect have exceeded our expectations and provide us with a new high-priority target. Extensive shallow historic workings in the prospect area so close to an operating mine encouraged us to test it and we will now explore for extensions at depth.
In addition the Gordons gold project continues to return excellent drilling results from a number of prospects and the mineralised footprint in the Gordons Dam area is expanding with each reconnaissance AC program. There is potential for a large gold deposit at depth similar in size to those in the area. We have commenced a detailed structural study to improve geology and mineralisation models and to direct further aggressive RC and diamond drilling at depth”.

Yandal Resources Ltd (ASX: YRL , “Yandal Resources” or the “Company”) is pleased to report new drilling 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 (Figure 1).
Star of Gordon Prospect
A total of 43 angled RC holes for 4,197m were completed during the March Quarter 2021[1] to test ~1.5km strike length of shallow historic workings and surficial prospecting areas (Figures 1, 2 & Table 1). RC drilling was used to penetrate primary rocks as the depth of strong weathering is generally very shallow at ~10-15m. Widespread mineralisation was encountered within transitional and primary mafic, ultramafic and porphyry rock types. The mineralisation is open in all directions. Highlights include;
-
➢ 3m @ 1.37g/t Au from 10m including 1m @ 2.32g/t (YRLRC491)
-
➢ 3m @ 1.28g/t Au from 18m including 1m @ 1.69g/t (YRLRC492)
-
➢ 5m @ 2.44g/t Au from 21m including 3m @ 3.25g/t (YRLRC493)
-
➢ 6m @ 1.37g/t Au from 94m including 1m @ 6.12g/t (YRLRC501)
-
➢ 2m @ 1.57g/t Au from 51m including 1m @ 2.63g/t (YRLRC503)
-
➢ 4m @ 0.86g/t Au from 40m including 1m @ 2.99g/t (YRLRC506)
-
➢ 3m @ 2.11g/t Au from 61m including 1m @ 3.67g/t (YRLRC506A)
-
➢ 5m @ 0.95g/t Au from 35m including 1m @ 2.73g/t (YRLRC507)
-
➢ 8m @ 4.69g/t Au from 15m including 2m @ 10.20g/t and 1m @ 13.29g/t (YRLRC513)
-
➢ 10m @ 2.53g/t Au from 27m including 2m @ 6.88g/t and 1m @ 8.56g/t (YRLRC514)
The mineralisation occurs <2km directly NNW along strike from the Gordon Sirdar underground gold mine which is owned and operated by FMR Investments Pty Ltd (“FMR”). FMR are currently mining ~60,000t of ore per month using conventional underground mining methods and transporting the ore via road haulage for processing at their mill in Coolgardie.
Considering the extent of historic workings, the proximity of the intercepts to known gold deposits and the limited historic drilling into primary rocks, the Company considers the prospect to be a high priority exploration target. Planning and preparation for follow-up RC drilling to test for mineralisation at 100-150m depth is underway with commencement planned in the September Quarter.
Malone Prospect
A total of 93 vertical AC holes for 5,650m were completed in February and March along strike from and in areas adjacent to known mineralisation within shallow palaeochannel sediments, porphyry and mafic rock types (Figures 1 & 3 and Tables 2 & 3). Numerous significant intercepts from 4m composite samples were previously reported from 74 holes[1] and now individual 1m samples have returned significant mineralisation. Highlights include;
-
➢ 4m @ 1.52g/t Au from 83m at end-of-hole (YRLAC590)
-
➢ 6m @ 0.47g/t Au from 53m including 1m @ 1.02g/t at end-of-hole (YRLAC612)
-
➢ 4m @ 0.62g/t Au from 59m including 1m @ 1.82g/t (YRLAC614)
-
➢ 3m @ 1.14g/t Au from 77m including 1m @ 2.25g/t and 3m @ 0.33g/t at end-of-hole (YRLAC628)
-
➢ 2m @ 1.17g/t Au from 58m including 1m @ 2.07g/t at end-of-hole (YRLAC632)
-
➢ 5m @ 1.94g/t Au from 65m including 1m @ 8.21g/t (YRLAC633)
In addition, 4m composite samples have been returned from the remainder of the program with assays defining additional new mineralisation (Figures 1, 3 & Table 3). Highlights include:
- ➢ 8m @ 0.19g/t Au from 68m (YRLAC616) ➢ 4m @ 3.01g/t Au from 80m (YRLAC648)

The new results are considered highly encouraging as they currently define a large transitional and bedrock anomaly extending for over 1km in a north-south direction and for over 500m in the east-west direction. The anomaly is open to the south-west and the western part of the anomaly is interpreted to be related to a NNW – SSE trending mafic - felsic volcanic contact. The underlying regional schematic geology interpretation map shown in Figure 3, is not currently accurate as it is in the process of being updated with recent information for future releases.
Results from the area in the vicinity of hole YRLAC648 (4m @ 3.01g/t Au from 80m ) are particularly encouraging as they define a linear +300m long east-west trending zone that is open to the west (Figure 3). Additional lines of first pass AC drilling are planned to commence in the current quarter with ongoing RC and diamond (“DD”) drilling planned for immediate follow-up.
RC drilling is currently underway at the Malone prospect to test new targets generated from the earlier AC results. An ongoing RC program is underway to test beneath the anomalies to maximum depths of 150200m depending on ground conditions (Figure 3). If results are successful, deeper RC and DD drilling will immediately follow. RC assay results are pending.
Gordons Dam SE Prospect
Individual 1m assay results were returned from anomalous 4m composite intervals from angled AC holes which have also provided better definition of the bedrock targets ~600m south-east along strike from the more advanced Gordons Dam prospect (Figures 1, 3 & Table 2). Highlights include;
-
➢ 2m @ 1.10g/t Au from 44m including 1m @ 1.23g/t Au at end-of-hole (YRLAC465)
-
➢ 4m @ 0.91g/t Au from 73m including 1m @ 1.65g/t Au at end-of-hole (YRLAC465)
Follow-up RC drilling has commenced to test beneath the most encouraging bedrock anomalies and further drilling is planned once the results of a detailed structural mineralisation study at Gordons Dam are received. RC assay results are pending.
Gordons Dam Prospect
As follow-up to high-grade primary intercepts returned from March Quarter RC drilling including 1m @ 20.68g/t Au from 118m in hole YRLRC543[1] and 1m @ 20.41g/t Au from 73m in hole YRLRC539[1] , a detailed structural mineralisation study was instigated. The study will be completed by Davis Vanderhor Geological Consultants and use all available drilling data including results from a recently completed DD hole YRLDD008.
The new hole was completed to 342.1m downhole depth and was designed to intersect porphyry hosted and related mineralisation at vertical depth of ~200m (Figure 3). Significant disseminated, brecciated and quartz hosted sulphides were noted within altered porphyry and mafic rocks in the drill core commencing very close to the interpreted target depth. DD assay results are pending.
Next Steps
Key exploration activities planned during the June and September Quarter at the Gordons project include;
-
Receive and review all pending AC, RC and DD drill hole results from Gordons Dam, Gordons Dam SE, Malone and Sheperd prospects and implement immediate follow-up high-impact drilling to test targets to maximum vertical depths of ~500m;
-
Compile results and implement recommendations from the structural mineralisation study;
-
Continue DD, RC and AC programs at the Gordons Dam, Gordons Dam SE, Malone and Star of Gordon prospects.
