AuKing Mining Limited (ASX:AKN) has identified a number of prime targets for its upcoming drilling programme at the Koongie Park Project in Western Australia for 2022..
The recent completion of a downhole electromagnetic (DHEM) survey of certain holes drilled last year has identified strong conductive sources at both Onedin and Sandiego that could be associated with significant copper and other base metals sulphide mineralisation.
Drill testing of these conductive sources adds significant interest to an already-detailed drilling programme expected to commence in late May.
A summary of the proposed drilling activities at Koongie Park is as follows:
- Onedin DHEM anomaly. The target zone for drilling is situated to the south-west of the existing Onedin deposit. AKN proposes to initially drill 3 holes of 450m depth (~1,400m total) with a combined 600m reverse circulation (RC) and 800m diamond drilling. The drilling will test the strong conductive sources identified in the recently completed DHEM survey that are shown to be offset from known mineralised zones at Onedin.
- Onedin South Exploration drilling will test a geophysical anomaly that sits along trend around 500m south of the existing Onedin resource (see figure 3 below). AKN intends to drill 16 RC holes for a total of 3,200m to test for shallow mineralisation in the area.
- Sandiego DHEM anomal.y The target zone is situated to the north-east of the existing Sandiego deposit. AKN proposes to drill an initial three to four holes of 450-550m depth (approx. 2,000m total) with a combined 800m reverse circulation (RC) and 1200m diamond drilling. The drilling is planned to test the strong conductive source identified in the recent DHEM survey that is shown to be offset from the known mineralised zone at Sandiego.
- Sandiego water bore target AKN previously announced a potential target zone of 700m to the north of the Sandiego deposit up to water bore hole ASWB001. This target zone was based on the following assay results reported in November 2021
Hole ASWB001 (Shallow hole (102m) a water bore at Sandiego): 5m @ 1.37% Cu from 50m and 2m @ 1.71% Cu from 85m These results are considered important as the drill hole is located over 700m north of the known mineralised zone at Sandiego and no previous drilling activities have identified significant copper or other metals in this area. In addition, as a water bore hole, drilling was terminated at 102m where good water flow rates were achieved, leaving open the possibility of further copper mineralisation at depth. The two intervals of Cu mineralisation in water bore ASWB001 display the now-typical Sandiego geochemical association with elevated Co and Ce/La/Y grades and this strongly suggests that this newly discovered mineralisation marks a potential northern continuation of the main Sandiego mineralised zone. The new discovery lies 720m north-northeast of ASRD005, the most northerly hole drilled during AKN’s 2021 Sandiego drilling campaign.AKN proposes to drill seven holes for 1,050m of RC drilling (max. hole depth 150m) and aims to test shallow mineralisation around ASWB001 and in the 700m target corridor.
- Emull AKN intends to drill an initial 8-11 holes to a maximum depth of 230m (~1,750m total) of RC drilling. The drilling is target shallow mineralisation previously intersected by Northern Star Resources during historic drilling in the early 2000’s
- E80/4960 anomaly AKN proposes to drill an additional 2-3 holes of a total 360m of RC drilling to test this geophysical anomaly that was identified by AKN during activities in 2021.
- Drilling programme and budget The drilling programme is expected to take approximately two months to complete, with an estimated budget of A$1.5M. Preliminary results from the RC samples by way of pXRF analysis should be available within days of completion of the particular drilling.
- Platinum Group Element (PGE) soil sampling – near Lamboo PGE Deposit There has already been considerable exploration undertaken at this project and an important feature of the PGE rights at Koongie Park is the outstanding recent drilling results reported by Pantoro Limited at its Lamboo PGE Project. These results demonstrate the location of significant PGE mineralisation in the lower and ultramafic portions of the Lamboo Igneous Complex That same ultramafic unit (called McIntosh) extends across a significant area of Koongie Park tenures – creating the potential of an estimated 12km strike length of the PGE mineralisation. An ultrafine soil sampling (UFSS) program will be completed over ground considered prospective for PGE mineralisation. AKN’s exploration team will complete sampling over the coming months as time permits. Priority targets for the UFSS will be the McIntosh suite that sits within the E80/5263 tenement. There is a 10km-12km stretch of the McIntosh suite that is a potential continuation of PNR’s PGE mineralisation that remains largely untested. 900-1200 samples will be collected over two phases. The first phase will be on a nominal 400m x 100m spacing and phase two will bring the spacing into 200m x 100m. The programme is expected to take two to three weeks per phase.
“The results of the downhole geophysics program could not have been better timed for AKN. The program has identified a number of high priority targets that will form the basis of our 2022 drill program, set to commence at Koongie Park in the coming weeks,” CEO, Paul Williams, said.
“The downhole electromagnetic (DHEM) survey has provided the company with two key zones of potential significant mineralisation which remain untested at both Onedin and Sandiego.
“Coupled with an intensive proposed drilling programme, which includes the anomalous zones at Onedin South and the long-awaited drilling at Emull AKN has an excellent platform to continue to produce strong results and potentially increase the recently upgraded resource estimate at Koongie Park.”
