Recent drilling across the Stallion REE Project has returned multiple stand-out results, which validate and improve upon historical exploration work conducted by Manhattan Corporation.

Step-out drilling to the west of the paleochannel at Stallion has also outlined a broad, shallow zone of potential rare earth element (REE) mineralisation, which remains open in all directions.

Summit Minerals (ASX:SUM) says the zone measures 1km x 1.25km with a thickness averaging 18m and grade average ~1,750ppm TREO.

Meanwhile, best results from the assays include 23m at 2,162.45ppm TREO from 24m, 15m at 3,088.84ppm TREO from 39m, and 17m at 3,783.4ppm TREO from 61m, including 1m at 1.52% TREO from 73m.

‘The scale potential is vast’

SUM managing director Jonathan King says the company is “delighted” to have generated such compelling numbers from much shallower depths than those encountered by previous explorers.

“The step-out drilling produced several suitably wide intersections and total rare earth oxide (TREO) grades exceeding 1,000ppm with a peak value of 1.52% TREO.

“The scale potential is vast, and it is early days, but the company may have identified a significant Ion Adsorption Deposit which is a fantastic result for the company in its maiden drilling program since IPO.”

Plan ahead

Summit now plans to use the existing coarse reject from the recent drilling to undertake metallurgical and mineralogical programs to progress towards a geometallurgical model for Stallion.

The company will utilise the available POW-approved drilling to build further certainty and definition within the identified zone as a precursor to developing its potential maiden resource.
