Infill Drilling Completed at Butcherbird Targeting Reserve Extension to Support Expansion

Element 25 Limited (E25 or Company) (ASX: E25; OTCQX: ELMTF) is pleased to advise that resource infill drilling has been completed at the Company’s 100%-owned Butcherbird Manganese Project (Butcherbird or Project). E25 recently completed a Feasibility Study (FS) to support the Butcherbird Expansion Project, which is targeting a nominal 1.1 million tonnes per annum of manganese concentrate production1.

Current reserves are based around mineral resources within granted mining lease M52/1074, of which less than half has been drilled to a sufficient density to meet the requirements for measured and indicated classifications. The balance is classified as inferred. The additional drilling will provide infill data to better define and potentially convert these areas to indicated or measured categories to support the re-estimation of mine reserves. The increase in the “reserve tail” will support project financing activities with NAIF and other potential financiers who are currently undertaking project expansion due diligence2.


  • 207 percussion drill holes have been completed for 6,202m targeting infill of existing inferred resources.
  • All samples have been dispatched to Bureau Veritas for assay with results pending.

The Project hosts a global resource of over 260Mt of manganese ore3 however the current reserves are limited to the areas which have been drilled out to measured and indicated classifications which are required as the basis for a statement of reserves. The current drilling programme was designed to infill existing inferred resources to a sufficient data density, based on variographic analysis, to convert the inferred resources within granted mining lease M52/1074 to indicated and/or measured.

The additional drilling information, combined with historical data, will be used to recalculate the resource base to support a recalculation of the proved and probable reserves to support project financing activities for the Butcherbird Expansion Project by increasing the “reserve tail”. Samples have been submitted for assay with results pending.

Element 25 Managing Director Justin Brown said:

“This drilling programme will allow the global resource at Butcherbird to be recalculated with a higher degree of certainty which is expected to result in a signification conversion of inferred resources to measured and indicated classifications to increase the reserve tail in support of the planned ramp up to 1.1Mt production rates.”
