Surefire Resources NL (ASX:SRN) (FRA:GBL) has intersected thick gold mineralisation with high-grade intervals from nine reverse circulation (RC) holes at Yidby Road prospect within Yidby Gold Project in the highly prospective southwest Murchison province of Western Australia.
This phase of the drilling is designed to follow up and extend testing of the thick and high-grade mineralised zone previously intersected and that returned 56 metres at 1.97 g/t gold from 44 metres, including 4 metres at 14.47 g/t gold.
New results include thick intersections with high-grade intervals from the central and southern part of the identified mineralised zone comprising 26 metres at 2.02 g/t gold from 126 metres, 14 metres at 3.01 g/t and 2 metres at 10.05 g/t.
This intersection is from one of three steeply dipping mineralised structures developed across a 200-metre-wide corridor, and that remains open at depth.
A step-out hole at the southern end of the currently identified deposit has also produced 58 metres at 0.83 g/t from 28 metres, including 7 metres at 2.07 g/t and 10 metres at 2.48 g/t.
Aiming to confirm new gold discovery
Managing director Vladimir Nikolaenko said: “We have identified multiple mineralised structures across a > 200-metre corridor and the deposit has only been drilled over a 200-metre strike length open to the north, south and at depth.”
Additionally, re-sampling of a 4-metre composite sample in YBRC017 included a 1-metre assay of 23.13 g/t gold and also resulted in the extension of the mineralised envelope in this hole to 100 metres at 0.53 g/t gold from 96 metres.
These results are from the final high-priority holes and the majority of drill hole results have now been received from the initial program, with only four remaining holes to come that were not completed to the target depth.
The key objectives of the current and planned drilling programs will be to grow the scale of the Yidby Road prospect and confirm the potential for a major new gold discovery.
Further drilling planned
Following interpretation and modelling of the mineralised structures, further drilling will be planned to test the thickening, high-grade, down-plunge extensions of these lode structures, both to the northwest and southeast, in order to further extend the current discovery.
In addition, MMI soil sampling results as well as gravity and magnetics interpretation indicates that the mineralised corridor extends at least another 400 metres to the northwest of the currently defined zone.
An additional PoW will be submitted shortly to allow the extension drilling to be planned with the objective of identifying further thick and gold mineralised structures within the Yidby Road corridor.
