    Regis completes Ben Hur maiden ore reserve estimate

    Regis Resources Limited (ASX: RRL) has announced the completion of a Mineral Resource and Maiden Ore Reserve Estimate for the Ben Hur deposit near Laverton in Western Australia.

    The company said that the acceleration of exploration at Ben Hur following the acquisition of the resource and tenement holdings from Stone Resources Australia Limited on 2 September 2020, grew the Mineral Resource by 34% and allowed the declaration of the maiden Ore Reserve.

    RRL reported that the Ben Hur Mineral Resources Estimate was increased to 10.3Mt at 1.2g/t Au for 390Koz Au, while the maiden Ben Hur Ore Reserve was 3.5Mt at 1.1g/t Au for 130Koz Au, assuming a A$1,600/oz gold price.

    Regis said that the infill and extensional drilling has confirmed broad zones of mineralisation analogous to the Baneygo and Rosemont deposits situated north-west along strike indicating further growth potential.

    Drilling at Ben Hur

    Immediately after the acquisition of Ben Hur from Stone Resources Australia, the company had commenced infill drilling to confirm and expand the existing Mineral Resource.

    The infill and extensional drilling consisted of 123 RC holes for 22,857m. Three diamond holes for 484m were completed to gain geotechnical information for mine design purposes.

    2021 Ben Hur MRE

    The company had internally completed the 2021 Ben Hur Mineral Resource Estimate (MRE) in compliance with the 2012 Edition of the JORC Code.

    RRL announced that the total Mineral Resource for the Ben Hur deposit reported above a 0.4g/t Au cut-off grade, is estimated to be 10.3Mt at 1.2g/t Au for a total of 390koz of Au. This includes 8.0Mt at 1.2g/t Indicated material for 300koz of Au.

    The database used in the current estimate includes records for 3,013 drill holes for 129,722 drill metres. This includes records for 12 diamond drill (DD) holes and 549 reverse circulation (RC) holes.

    Ore Reserve estimate

    The company said that it had completed the March 2021 Ore Reserve estimate through the assessment of modifying factors on the Indicated components of the updated Mineral Resource estimate. The Maiden Ben Hur Ore Reserve was reported to be 3.5Mt at 1.1g/t Au for 130Koz Au, assuming a A$1,600/oz gold price.

    What’s next?

    The company reported that future Ben Hur RC strike extension drill program has been designed to test the quartz dolerite host unit ~1km north and south along strike from the current Ben Hur Resource drill-out, with the aim of adding an additional 150-200koz through the discovery of additional open pits.

    RRL said that drilling is planned on a 200m line spacing and 50m hole spacing and has been designed to test the quartz-dolerite host unit between 30-70 metres below surface, below depletion but above fresh rock.

    Mineralisation at Ben Hur is analogous to the Baneygo and Rosemont deposits situated north-west along strike from Ben Hur, where gold is hosted within a stockwork of quartz stringers.

    Management statements

    Regis Managing Director, Jim Beyer commented: “Regis prioritised the work at Ben Hur and as a result the team has been able to efficiently realise some of the potential of the project within 7 months of acquiring it.

    The maiden Reserve feeds straight into Regis’ strategy of internal value growth through mine life extension for our Duketon operations. We remain very excited by the potential for continued exploration success at Ben Hur and across the Duketon Greenstone Belt generally.”
