Copper Enriched Zone Near Surface at Kaiser

Alkane is pleased to announce further results from its initial resource drilling program at the Company’s Kaiser Prospect in Central New South Wales.

Kaiser is approximately one kilometre northwest of Boda, a landmark porphyry gold-copper system within the Northern Molong Porphyry Project, which the Company believes has the potential to be a large, tier one gold-copper project. Alkane also operates the nearby Tomingley Gold Operations.

Resource drilling at the Kaiser prospect, centred 1km northwest of the Boda resource, has intersected significant copper-gold porphyry mineralisation including:

KAI082134m grading 0.85% Cu, 0.71g/t Au from 211m
incl68m grading 1.50% Cu, 1.17g/t Au from 249m
KAI075104m grading 0.39% Cu, 0.18g/t Au from 150m
incl6m grading 0.70% Cu, 0.28g/t Au from 207m
and54m grading 0.36% Cu, 0.23g/t Au from 265m
incl4m grading 0.63% Cu, 0.38g/t Au from 291m
KAI08138m grading 0.48% Cu, 0.20g/t Au from 45m
incl13m grading 1.05% Cu, 0.35g/t Au from 49m
and70m grading 0.26% Cu, 0.14g/t Au from 175m
incl11m grading 0.45% Cu, 0.29g/t Au from 196m

The porphyry mineralisation intersected in the northwest area of Kaiser appears more copper enriched with bornite and chalcocite commonly observed. The KAI082 Cu-Au intercept is the best recorded at Kaiser to date.

At the Korridor (Boda Northwest Extension) prospect, approximately 500m southeast of Kaiser, results were received from deep diamond core drilling that is targeting the apparent northwest plunge to the Boda resource. This drilling intersected broad gold-copper mineralisation, with significant intercepts including:

KSRC041D566m grading 0.26g/t Au, 0.14% Cu from 631m
incl113m grading 0.60g/t Au, 0.21% Cu from 1,059m
BOD089427m grading 0.26g/t Au, 0.15% Cu from 684m
incl6m grading 1.07g/t Au, 0.25% Cu from 960m

Results were received from four deep diamond core drill holes for the Boda Two/Three prospects. These holes were designed to test the north-south continuation of broad gold-copper mineralisation intersected in previously announced drillholes.

Significant intercepts include:

BOD064445m grading 0.25g/t Au, 0.13% Cu from 451m
and57m grading 0.26g/t Au, 0.10% Cu from 967m
and120m grading 0.33g/t Au, 0.15% Cu from 1,119m
and50m grading 0.41/t Au, 0.18% Cu from 1,298m
KSDD03912m grading 1.47g/t Au, 0.73% Cu from 688m
and308m grading 0.35g/t Au, 0.17% Cu from 803m

The 100m x 100m grid drilling at Kaiser to identify mineralisation amenable to open cut mining is nearing completion with two diamond core rigs mobilised to diamond tail selected RC holes to greater depths where necessary. Drilling operations are expected to be completed by the end of the month. The resource estimation is now expected in Q1 2023 due to an extension of the drilling program to the northwest and delays associated with persistent heavy rainfall.

Recently acquired Induced Polarisation (IP) with Magnetotelluric (MT) survey completed over the northwest structural corridor area extending 5km north-west of Kaiser, identified two high-priority targets. The first target has been RC drill tested with observations of pyrite and trace chalcopyrite mineralisation associated with inner propylitic alteration. Further drilling is planned in October 2022.

A major RC and diamond core infill drilling program designed at the Boda Two and Boda Three prospects will commence immediately after the Kaiser drilling is completed.

Alkane Managing Director, Nic Earner, said, “The initial shallow resource drilling program at Kaiser is revealing a copper enriched near-surface zone that appears to be increasing in grade to the northwest. We’re greatly encouraged by these recent results, both by their grade and their proximity to surface.

“With mineralisation over three kilometres from Boda Three to Kaiser, open along strike and at depth and further targets identified along trend to the northwest of Kaiser we clearly have a significant system. Drilling continues both at Kaiser, with Boda Two and Three to follow.”
