The information relating to mineral resources for the Sulphur Springs, Kangaroo Caves, Mons Cupri and Salt Creek Deposits were prepared by Mr David Milton, Director of Mil Min Pty Ltd. All information and technical parameter underpinning the estimates have been released to the market in the following ASX announcements “Sulphur Springs Resource Update” dated 11 May 2016, “Sulphur Springs Resource Upgrade” dated 21 March 2018, “Kangaroo Caves Resource Upgrade” dated 22 September 2015, and “Whim Creek Project Resources Update” dated 25 March 2018.
All information and technical parameters underpinning the estimated Mineral Resources for the Whim Creek and Evelyn Deposits have been detailed in the Company’s ASX announcement “Company Resource and Reserve Statement as at 30 September 2013” which was released to the market on 8 October 2013. The company is not aware of any new information or data that materially affects the Mineral Resources for either of these deposits.
The information and assumptions relating to the Sulphur Springs Open Pit and Underground Ore Reserve is based on information compiled or reviewed by Mr Daniel Donald, of Entech Pty Ltd. The information that relates to interpretation of metallurgical test work and process plant design is based on information compiled or reviewed by Mr Aidan Ryan, an employee of Lycopodium Minerals Pty Ltd. All information and technical assumptions underpinning the Ore Reserves for the Sulphur Springs Deposit has been released to the market in the 16 February 2017 announcement “Value Engineering Study – Sulphur Springs Zinc-Copper Project a Robust Development Opportunity”, and an earlier announcement titled “Updated Sulphur Springs Ore Reserve: New mine plan achieves significant capital and operating cost savings” released on 28 June 2016. The stated reserves are based on the assumptions described in the 2016 VES, published 16 February 2017. The outcomes of subsequent resource drilling and metallurgical testing have not been taken into account at this stage.
