Westar Resources Ltd (ASX:WSR) has completed a maiden reverse circulation (RC) drilling program at the Gidgee South Gold Project and is poised to start an extensive inaugural campaign at the Winjangoo Gold Project.
A total of 56 RC drill holes were completed for 4,258 metres of drill advance across multiple high-priority targets, including the historical Birrigrin Mining Centre (BMC) with assay results to be received in a few weeks.
The rig and crews have re-mobilised to begin the maiden RC drilling program at Winjangoo Project, 25 kilometres north of Mt Magnet.
“Indicators of potential mineralisation”
Westar managing director Karl Jupp said: ”We are excited to have completed the maiden RC drilling program at the Gidgee South Gold Project and noted many of the holes intersected indicators of potential mineralisation, which validates our conceptual mineralisation model.
The company plans about 4,000 metres of drilling at Winjangoo to test several high-priority targets.
These targets are based on coincident auger geochemical anomalies, outcropping quartz veins with oxidised pyrite, surface alteration, structurally deformed and sheared granite-greenstone contacts as well as recent prospector activity.
Jupp said: “At Winjangoo our geologists have identified several highly prospective targets based on a combination of geochemical anomalies, airborne magnetic interpretations and convergence of outcropping pyritic quartz veins.
“These areas have never been drill tested and are all highly prospective”
Massive quartz veining
At the outset, Westar’s RC drilling program was based on detailed targeting in conjunction with specialist consultants PGN Geoscience, high-priority targets were identified and systematically ranked through analysis of datasets.
Geological logging of holes at Gidgee South indicated frequent quartz-bearing structures with minor chlorite alteration as well as noting frequent limonite-hematite alteration along the contact margins of basalts and granite/aplite dykes.
At the Birrigrin Mining Centre (BMC), drilling intercepted several intervals of massive quartz veining, with additional intervals of moderate veining accompanied by chlorite-silica and limonitic alteration.
The historical mines at the BMC, including Wheal Ellen, Pelerin and Hawthorn, are documented to have targeted similar quartz reef structures.
The RC drilling program was undertaken by Western Australian based drilling company, Frontline Drilling, and all samples have been submitted for assaying at ALS Perth.
The Deep Ground Penetrating Radar (DGPR) survey recently completed over selected areas of the Birrigrin Mining Centre and Gidgee South are currently being reviewed and incorporated into Westar datasets.
Targets at Winjangoo
Westar’s maiden RC drilling program at Winjangoo is designed to test several priority drill targets within a broad mineralisation corridor identified from geochemical auger sampling.
This forms one of the two Mount Magnet projects on granted exploration licences - the Winjangoo Project (E58/536) and the Coolaloo Project (E59/2329) - with both in the Murchison Mineral Field.
Historical exploration at Winjangoo is limited to minor geochemical programs, desktop studies, regional geophysical programs and geological mapping over limited portions of the project area.
The drilling is designed as a staged program to an approximate 80 metres depth, with the flexibility to extend holes if prospective geology or indicators of mineralisation are intersected during drilling.
Furthermore, the program also includes several priority 2 holes that can be immediately drilled pending success of the priority 1 holes.
The activities of Westar at Winjangoo to date have included regional reconnaissance and field mapping, airborne geophysical survey, an auger soil geochemical program of 749 samples, target generation, ranking and prioritisation and heritage surveys.
