Alkane Resources Unearths High-Grade Gold-Antimony Zones at Kendal Deposit
PERTH, Australia – Alkane Resources Limited (OTCQX: ALKEF) has reported significant near-mine, high-grade gold and antimony results from its Kendal deposit, located adjacent to the Costerfield operation in Victoria, Australia. The latest exploration drilling has delineated an extensive vein system, revealing exceptional intercepts that underscore the deposit’s potential to bolster Costerfield’s ore production.
The Kendal system, characterized by its rich antimony content, is understood to be an up-dip continuation of the high-grade Youle and Shepherd deposits, which are currently being mined. This recent drilling program has successfully extended the known footprint of the vein system, both adjacent to and offset from historical mine workings. Notably, the drilling has uncovered significant veining that was previously undiscovered during the mine’s historical operational period between 1861 and 1939.
Among the standout results, drill hole BC464 returned an impressive 2.3 meters grading 267.5 grams per tonne of gold (g/t Au) and 5.6% antimony (Sb). Another significant intercept was reported in hole PD222, yielding 1.94 meters of 132.2 g/t Au and 19.8% Sb. The assays highlight areas of very high gold and antimony grades, historically correlated with enhanced production rates.
Development to access the expanded Kendal system commenced in late 2025 and is ongoing, with extension drilling continuing to define the extent of the mineralization. Alkane Managing Director & CEO, Nic Earner, expressed optimism regarding the findings, stating, “The drilling results obtained from the Kendal deposit over the past year demonstrate the large potential remaining for significant high-grade mineralisation at shallow levels near to the Costerfield mine. Accessing and mining the newly defined mineralisation is a top priority for the Costerfield team and should provide the processing plant with an additional source of high-grade gold and antimony ore for some time to come.”
The Kendal system currently spans approximately 600 meters of strike length, with 25 distinct veins delineated. Individual veins, such as the 520 vein, have been traced over an interpreted 500 meters of strike and up to 200 meters of vertical extent, providing strong geological continuity. The overall geometry of the Kendal vein system exhibits an average width of around 70 meters across much of its strike.
The high antimony content observed in the Kendal system, with assay results for Sb reaching up to 50.5% in some intervals, is particularly noteworthy. This significantly exceeds the antimony content found in the Shepherd system, a primary ore source for the Costerfield operation, and is found alongside very high gold values.
While these results are promising, Alkane has not yet reported a formal mineral resource for the Kendal deposit, pending further modeling. Historical intercepts, where presented for context, have not been independently verified by Alkane and are considered indicative. Further drilling is planned, with programs expected to resume in 2026 to refine the understanding of the deposit’s geometry and grade distribution.
The Costerfield operation has a rich history dating back to 1861, with modern mining operations having been continuous since 2006. The deposit’s geology is complex, situated on the hinge and western flank of the Costerfield Anticline. The veins are predominantly quartz and carbonate, grading to massive stibnite towards their core, with gold present throughout.
Alkane Resources anticipates that the integration of the Kendal mineral resources into the Costerfield resource and life-of-mine plan will be a key focus moving forward, reinforcing the company’s position as a significant gold and antimony producer.
