Buxton Resources Limited (ASX:BUX) has identified a bedrock conductor along strike from the Ministry Prospect at the companys 100% owned Narryer Project in Western Australia.
The new information was contained in recently released data from the WA government funded AusEM Murchison survey. The AusEM Murchison survey is a government-funded airborne EM (AEM) survey which has a nominal 20 km line spacing.
Three east-west oriented lines intersect Buxton’s Narryer Project. A strong anomaly is apparent on line 300801 around 1.8km south-southwest along geological strike from the Ministry Prospect.
The Ministry Prospect AEM anomaly is apparent in the original SkyTEM survey dataset and is confirmed by Geoscience Australia’s subsequent inversion modelling.
After review of the detailed raw survey data, independent geophysicist Russell Mortimer has described the Ministry AEM anomaly as a “legitimate bedrock conductor”.
Buxton’s reconnaissance mapping and rock chip assaying at Ministry project has confirmed the presence of ultramafic rocks (up to 18.8% MgO) and ironstones with elevated nickel (5,030 ppm), copper (543 ppm) and platinum group elements (34 ppb Pd, 18 ppb Pt, 24 ppb Au).
Buxton has contracted XCalibur Multiscience to acquire a minimum of 1,990-line kilometres of AEM with their state-of-the-art HeliTEM2 system, which operates at low base-frequency of 6.25 Hz.
This low base-frequency system will allow for substantially greater penetration in areas of conductive cover compared with the 25 Hz system operated by SkyTEM for the AusAEM Murchison Survey.
This Buxton’s AEM survey targets multiple gravity high anomalies most of which are completely covered by a thin veneer of transported sediments and have seen no previous AEM. Previous AEM surveys which cover Buxton’s Narryer Project tenure now amount to just 156-line kilometres, over half of which is attributable to the three lines from the new Murchison AEM survey.
This combined historical AEM coverage accounts for just 1.7% of the Project tenure, assuming a 200-metre effective width of investigation for AEM surveys. The survey areas will be flown with a nominal at 200 metre line spacing to ensure complete coverage. XCalibur has advised a mid-June start date for this survey.
