Extension drilling in the first four months of this year at the Samphire Uranium Project in South Australia has enabled Alligator Energy Ltd (ASX: AGE) to extend the mineralisation of its Blackbush deposit, identifying notable uranium intersections in roll fronts.
The drilling – which targeted wider target areas at Blackbush – yielded results including 0.75 meters at 0.64 percent (or 6,450 parts per million) pU3O8 (uranium grade) from 63.57 metres; and 4.44 metres at 0.43% (4,370ppm) pU3O8 from 61.38 metres.
A key goal of the 49-hole drill program was better refinement of Blackbush’s uranium roll front morphology, and the identification of step-out targets for further drilling in mid-May.
Roll front uranium deposits normally follow an arc-like shape, crosscutting the sandstone bedding.
Alligator’s CEO Greg Hall said he was pleased with the drilling results, which supported the company’s exploration strategy in relation to key targets.
“We are pleased to see Blackbush deposit mineralisation extending within the immediate target areas of the current resource to the west and east initially,” he said.
“The resource geology team is becoming adept at finding the redox boundary between oxidised and reduced sands, and hence quickly narrowing the search for the potentially economic roll front structures.
“In some instances, we are aided by the great exploration work done by the predecessor
company historical gamma drilling intersections.”
Samphire – which is located near Whyalla – will have a drilling contractor present on site until the end of 2024, with a resource update expected in the fourth quarter.
Alligator Energy has been trading 5% up at 6.3c.
