Blaze Minerals (ASX:BLZ) announces it has drilled 12 holes for 1,627m following a program at its Earaheedy Basin Project in Western Australia that started in late July.
To date the drilling within E69/3815 has been on a wide spaced nominal drill pattern, targeting the prospective stratigraphy, which hosts the adjacent Rumble Resources (ASX:RTR), Sweetwater, Chinook, Tonka, and Navajoh discoveries. E69/3815 is located on the unconformity contact zone between the Frere and Yelma formations, part of the Earaheedy Basin prospective stratigraphy.
Blaze reports that ‘highly’ anomalous portable X-Ray Fluorescence (XRF) base metal readings have been recorded in mineralised bedrock in 5 out of the 12 holes drilled within the contact unconformity zone between the Frere and Yelma formations.
The company’s share price had surged almost 20% as of 11.30am AWST.

The following results obtained via pXRF determination should be considered preliminary and subject to confirmation by subsequent geochemical analysis, with samples due to be received by the laboratory in the coming few days.
- BERC8 returned pXRF readings of 9m @ 1.69% zinc, and 0.07% lead, within an overall intersection of 21m @ 0.68% zinc and 0.11% lead from 88→109m.
- BERC6 returned pXRF readings of 21m @ 0.23% zinc, and 0.12% lead from 27→48m.
- BERC6 returned pXRF readings of 21m @ 0.23% zinc, and 0.12% lead from 58→68m.
- BERC7 returned pXRF readings of 10m @ 0.13% zinc, and 0.07% Lead from 58→68m.
The first 5 holes were designed to test the potential of the Iroquois carbonate dolomite formation within Blaze Mineral tenement E69/3815 with the contact zone tested with no anomalous results returned.
The company reports that the drilling then moved to the east to evaluate and test for the Frere/Yelma unconformity which was successfully intersected in all holes reaching target depth.
A number of areas were covered by up to 50m of Tertiary clays and colluvium which masks large portions of potential mineralisation within the tenement.
The mineralised zones were characterised by quartz veining, sulphide accumulations (pyrite, galena very fine-grained sphalerite) in fresh rock and in the oxide zones, gossanous ferruginous rocks.
The drilling to date has been spread over approximately 4km with the prospective Yelma uncomformity successfully intersected and tested over a 2km extent. Results have revealed a shallowly dipping (nominally 5 degrees to the north-northwest) sequence of the Yelma and Frere contact zone with intersections in all of the holes reaching target depth.
