Kin Mining NL (ASX: KIN) announced that the final results from the recently completed follow-up air-core (AC) drilling program at the Eagle-Crow prospect within the Cardinia Gold Project (CGP) in Western Australia have returned further significant zones of shallow, high-grade gold mineralisation.
The company reported significant assays of up to 4m at 38.8g/t gold from shallow air-core drilling, with mineralisation showing early-stage similarities to the Bruno-Lewis and Cardinia Hill deposits.
Best 4-metre composite assay results included 8m at 19.8g/t Au from 40m, including 4m at 38.8g/t Au from 44m (EG21AC400); 8m at 1.09g/t Au from 20m (EG21AC298); and 4m at 1.01g/t Au from 8m (EG21AC342).
KIN reported that the latest results build on numerous previously-reported high-grade intercepts at Eagle-Crow in adjacent lines of drilling, which indicate the extensive nature of the mineralisation. The company said that the broad-spaced AC drilling has defined two parallel zones of mineralisation, highlighting the potential for extensive, shallow gold discovery.
KIN has currently completed drilling across 18 lines that span 3.8km, including a number of in-fill lines to complete the 200m-spaced AC program. The company said that initial Diamond (DD) and Reverse Circulation (RC) drilling to confirm the orientation and extension of the shallow mineralisation below the oxide zone will commence following the completion of drilling at the Rangoon and Cardinia Hill deposits.
Follow-up AC drilling at Eagle-Crow
An initial program of air-core (AC) drilling at Eagle-Crow was completed in March, comprising 399 drill-holes for 17,035m. The program was designed to provide an assessment of the source of the extensive gold-in soil geochemical anomaly at Eagle-Crow, which extends over a strike length of approximately 5km and a width of 0.6km.
The company had then completed a follow-up AC program in April 2021, comprising 6 holes for 412m of drilling. Drilling has been completed across 18 lines that span 3.8km, including a number of in-fill lines to complete the 200m-spaced AC program.
High-grade initial results
KIN said that the infill drilling at the Crow prospect had delivered an outstanding intercept of 8m at 19.77g/t Au (including 4m at 38.8g/t Au) from hole EG21AC400, located 200m along strike from an intercept of 8m at 7.90g/t Au intersected in hole EG21AC072 in the previous round of drilling. Historical AC drilling on this mineralised trend intersected 3m at 4.5g/t and 3m at 27.1g/t Au adjacent to old surface workings
The company has now reported the assays for the remaining 115 holes (including the 6 follow up holes) and 4,186m.
Further shallow, high-grade intercepts
The company reported that at the Eagle prospect, extension lines to the south intersected 8m at 1.09g/t Au and several 4m intersections at between 1.01g/t and 1.93g/t Au.
Two parallel zones of mineralisation
KIN said that the latest results continue to reinforce the interpretation that the Crow prospect hosts two zones of coherent gold mineralisation extending over approximately 600m strike.
Outstanding 4m composite assay results from follow-up air-core (AC) drilling at the new Eagle-Crow prospect included 8m at 19.8g/t Au from 40m, including 4m at 38.8g/t Au from 44m (EG21AC400); 8m at 1.09g/t Au from 20m (EG21AC298); 4m at 1.93g/t Au from 28m (EG21AC310); 4m at 1.04g/t Au from 16m (EG21AC341); and 4m at 1.01g/t Au from 8m (EG21AC342).
All significant intercepts for the follow up Eagle-Crow Air-core (AC) drilling are as shown below.
The company said that the latest results build on numerous previously-reported high-grade intercepts at Eagle-Crow in adjacent lines of drilling, which indicate the extensive nature of the mineralisation.
Similarities to Bruno Lewis
The company said that the mineralisation at Eagle-Crow occurs as two interpreted styles: stratigraphically-controlled structures and north-east dipping cross-cutting structures. Both styles of mineralisation are seen at the nearby Bruno Lewis deposit, as well as other deposits across Cardinia.
Next steps
The company said that once Phase 4 RC drilling is complete at the nearby Rangoon and Cardinia Hill deposits, initial Diamond (DD) and Reverse Circulation (RC) drilling to confirm the orientation and extension of the shallow mineralisation below the oxide zone will commence. KIN said that the drilling to confirm the style and orientation of the gold mineralisation below the regolith is in the early stages of planning.
KIN reported that it intends to continue exploration and drilling activities, with the intention to increase the project’s resources.
“These latest results further reinforce our enthusiasm about this western side of the Cardinia Gold Project”
Management comments
Kin Mining Managing Director, Andrew Munckton, said: “These latest results further reinforce our enthusiasm about this western side of the Cardinia Gold Project, with Eagle-Crow showing plenty of early-stage similarities to the nearby Bruno-Lewis deposit and the rapidly-emerging Cardinia Hill deposit.
Based on this successful air-core drilling program, we have now confirmed the presence of two parallel zones of mineralisation at Eagle-Crow, with follow-up RC and diamond drilling to be undertaken as soon as the rigs complete the current drill programs underway at Rangoon and Cardinia Hill, which is expected around mid- June.
While Eagle-Crow remains an early-stage exploration target, the results that we’re seeing indicate exciting potential to delineate a new, shallow, high-grade gold discovery to organically grow the 1.23Moz Cardinia Gold Project.”
