Additional Significant Gold Results From First Deep AC Drilling
Kingwest Resouces Ltd (ASX:KWR) has identified an extensive gold anomalism and mineralisation in aircore drilling over more than 1,000m strike length at its Goongarrie Gold Project (GGP) in Western Australia.
Final gold assay results have uncovered additional significant gold results from Kingwest’s first deep Aircore drilling program at the highly prospective Goongarrie Gold Project.
Deep aircore drilling tested aeromagnetically defined lithostructural targets in five areas. Three areas Targets A9, A9 North, A6 and A5 have all returned significant gold results in the weathering zone, which Kingwest believe may be indicative of more extensive primary gold mineralisation in the underlying bedrock.
At Target A9gold mineralisation on five 200m-spaced lines has defined a 1,200m long by 300m wide zone of strongly anomalous gold geochemistry and gold mineralisation that is open along strike to the north and south
Target A9is just east of the Victorious Basalt/Black Flag Group (VB/BFG) contact, in an ultramafic and mafic volcanic sequence within the lower part of the Black Flag Group felsic metasediments. This is the same geological setting as the Goongarrie Lady gold deposit 2.5km to the north2 and as Ardea Resources Aphrodite North gold discovery 200m to the south3.
The Target A9gold discovery has strong gold depletion in the upper part of the weathering zone and is progressively covered by up to 50m of alluvial lake clay sediments as it heads south.
Where exposed in the north, it has been drilled to the base of weathering with a best intersection of 6m @ 17.2 g/t Au from 94m in KGA038.
South of there, drilling intersected broad intervals of lower-level gold in the gold-depleted weathering zone and beneath the alluvial lake cover.
CEO, Ed Turner, said this zone now requires deeper, closely spaced drilling to investigate the extent and grade of gold mineralisation in the underlying fresh bedrock
At Target A9 Northdeeper drilling is required to test this sequence in fresh rock, below the anomalous zone and along strike to the north and south.
At Target A6 Hole KGA0210 returned 4m @ 1.34 g/t Au from 6-10m depth. Shallow low-level gold anomalies are also present in adjacent holes KGA0208, KGA0209, KGA0212 and KGA0213. This 300m wide zone of gold anomalies and mineralisation is open along strike along for 500m to the north and for 3,000m to the south, where Kingwest has just been granted tenements P29/2531 and P29/2533 and now has surface access. Its potential significance is enhanced by the general depletion of gold in the upper part of the weathering zone, and it requires deep drilling below and along strike of the mineralisation.
At Target A5 a traverse intersected a complex, quartz-veined sequence of mafic, ultramafic and felsic metasedimentary rocks with low grade gold anomalism throughout. Higher grade intersections in KGA0271 (4m@ 0.32 g/t Au from 54-58m), KGA0280 (4m @ 0.35 g/t Au from 34-38m) and KGA0282 (4m @ 0.53 g/t Au from 30-34m) correspond to NW D4 cross-structures interpreted from the aeromagnetics. Follow up drilling at depth and along strike is required to better test this target.
Meanwhile, Kingwest has significantly progressed exploration of the previously inaccessible major part of the Goongarrie project that lies beneath the Goongarrie Salt Lake.
A high-resolution aeromagnetic study has been completed over the western half of Lake Goongarrie and a few of the resulting lithostructural targets have been tested by a program of deep geochemical pitting.
This deep pitting program was limited in extent but it has successfully located several strongly gold- anomalous drilling targets under previously unexplored areas of Lake Goongarrie.
The most promising of these targets to date is the A10 target, which lies at the intersection of a 500m wide NW-trending D4 shear zone with a thick Black Flag Group conglomerate unit. The geological setting of this target is similar to that of the 6.4Moz Kanowna Belle gold deposit, which lies 80km along strike to the southeast, at the intersection of three NW-trending D4 shears and the hanging wall of the Black Flag Group Golden Valley Conglomerate4. Deep pitting of the new Target A10 has found strong gold anomalism of up to 361ppb Au at the lake sediment interface above this conglomerate’s hanging wall contact. A10 is one of several compelling gold exploration drilling targets found beneath the lake cover.
A track-mounted drilling rig is scheduled to test Target A10along with Targets A1, A2 and A3in Q2, 2021.
“Our exploration programmes at Goongarrie continue to indicate how prospective the project is for major gold deposits,” Mr Turner said.
“We look forward to following up these results with more detailed drilling at Target A9 as well as initial drilling of Targets A1, A2, A3 and A10 which lie under the salt lakes in the north of the project.”
