WA Cu-Au
Lateron
The Lateron Project consists of Exploration License E80/5545 located on unclaimed crown land approximately 10 km East of Billiluna and 150 km South of Halls Creek in Western Australia, and is readily accessible via the Tanami Road and existing station tracks (Figure 1).
This EL covers magnetic anomalies related to sulphide bearing mafic / ultramafic intrusions intersected during historic exploration in the early 1980s for which assays were not reported at the time, and have not since been followed-up.
Historic diamond drilling by AFMECO in 1982 targeted roll front uranium mineralization in Paleozoic sediments. One of these holes intersected shallow “basement” rocks at 77.5 m vertical depth in hole S-19. The drill logs for this hole indicate the basement lithology consists of “basic, foliated, coarse grained pyroxenite containing abundant pyrite, hematitic quartz veins and dolerite differentiations”. AFMECO reported no geochemical assay results for any of their drill holes which were instead systematically logged by a wireline gamma probe (a geophysical tool sensitive to uranium mineralisation).
Detailed (150 m line spaced) airborne magnetic surveys indicate that this suite of intrusive rocks underlies an area of approximately 7 km2. Recent (2017) airborne gravity surveying indicates that a discrete gravity anomaly is also associated with these intrusions (Figure 2).
Buxton intends to investigate the potential for magmatic and/or hydrothermal base & precious metal mineralisation associated with these sulphide bearing intrusions.

Figure 2. Airborne magnetic features and airborne gravity contours shows the suite of intrusive rocks and gravity anomoly associated with such intrusions.
Buxton visited the drillsite and recovered 75 g of core material from the intrusive amongst much discarded core from the Devonian sedimentary sequence.
Petrologic assessment of this material for BUX indicates the lithology is biotite hornblende quartz diorite, with coarse titanite and sericite / muscovite pyrite-magnetite-chalcopyrite overprint. This lithology and alteration style is consistent with various types of magmatic-hydrothermal Cu-Au mineralisation. Follow-up IP and drilling programs are in planning to test this greenfields exploration target.
