Summit Minerals (ASX:SUM) is planning another bout of extension and infill drilling across its Stallion Rare Earth Element (REE) Project after receiving fresh assay results.
The phase three drilling campaign will look to grow the mineralised zone in the project area by expanding onto the adjacent tenement.
This news comes after recent phase two results confirmed that the mineralised zone trends north onto Summit’s adjacent tenement.

Recent assays include drillhole STRC023 with 9m @ 1,664.12ppm total rare earth oxides (TREO) from 58m; drillhole STRC017 with 34m @ 1,021.8ppm TREO from 37m; and drillhole STRC019 with 31m @ 1,298.37ppm TREO from 63m.
Commenting on the results, Summit Minerals Exploration Manager Jonathan King says: “The new results confirm the geometry of the mineralised blanket, generating confidence in our ability to establish a rare earth oxide resource at Stallion.
The REO mineralisation is likely associated with an acid-soluble secondary phosphate or silicate mineral.
Metallurgical testing, including mineral identification and liberation analysis, upgrading by simple beneficiation and acid leaching is underway, and the company looks forward to potentially reporting its maiden resource once this phase of work is complete.”

Phase two drilling comprised 14 holes for 820m, with new mineralisation intercepted utilising a 500 parts per million (ppm) TREO cut-off.
The Stallion REE Project is located in Ponton River, Western Australia.
