Yandal Resources Ltd (ASX:YRL) has received positive results from a recently completed Sub Audio Magnetic (SAM) survey at the Gordons Dam prospect within the Gordons Gold Project in the Kalgoorlie-Boulder region of WA.
The SAM survey identified eight new exploration target areas related to primary conductors to the south-west, north-west and east of known mineralisation.
Findings from the survey indicate the presence of an east-dipping mafic rock sequence and structures which have confirmed Yandal’s general interpretation from its March 2019 RC drilling program.

The Gordons Dam prospect area lies on a mafic volcanic-felsic sedimentary package.
The identification of individual porphyry rock units known to host gold from earlier drilling is interpreted to be obscured by the geophysical signatures of the mafic rocks however the structures are the key exploration targets.
The new targets (G1-G8) are currently being reviewed against the drill hole database for further refinement and prioritisation ahead of drilling in September.

Yandal managing director Lorry Hughes said: “The first pass SAM survey appears to have delineated coincident structural and conductive targets in a number of positions along strike from gold mineralisation intersected in reconnaissance style drilling.
“SAM is a geophysical technique that allows for the simultaneous high definition mapping of both the magnetic and electrical properties in the ground and it is well suited to overcome the difficulties of highly conductive surface layers such as those contained in salt lake environments which occur in the Gordons prospect area.
“The new targets confirm the highly prospective mineral potential of the Gordons Dam prospect and the company is advancing approvals and conducting preparatory activities ahead of RC drill testing in September”.
