Windward Resources has provided an update on the work completed at the Brookman Gold prospect, located on its Fraser Range North tenement in WA.
The company has completed and received all assay results from the 1,500m Reverse Circulation (RC) drill program, which consisted of a total of five RC drill holes completed on variable drill spacings ranging from 540m to 2,200m covering a 5km strike of the Brookman gold anomaly.
“Drilling returned a maximum assay result of 1m @ 1.02 g/t gold from 212m down-hole,” the company told the ASX.
“The program was designed to test at depth for gold mineralisation which had been identified from earlier, shallower drilling. Previous drilling (aircore, RAB and RC) had identified multiple, stacked weakly mineralised horizons dipping shallowly to the south-east.”
According to the assay results, the anomalous elemental suite (Au, Bi, Te, S, Cu-Mo) is similar to that more commonly recognised within Archaean Terranes.
“The drilling was aimed at testing these structures at depth (approximately 260m below surface), well below weathering and any possible supergene enrichment,” reads the statement.
“The bedrock lithology intersected was consistent throughout comprising a biotite/muscovite/garnet bearing schist (regional metasediment). Quartz veining was common throughout, associated with a slight increase of disseminated pyrite which was noted within restricted intervals (2-6m) throughout the drilling. The southernmost hole was noticeably lacking in garnet.”
Windward said the drilling demonstrated that the grade and/or width of the auriferous horizons do not increase in depth.
“Based on the outcomes of this drilling it can be assumed that there has been a component of supergene upgrading of these horizons (planes) closer to the surface,” it says in the statement.
According to the company, no further drilling is planned at the Brookman prospect at this stage.
