Allkem Limited Provides an Ore Reserve Update for Its Mt Cattlin Operation in Western Australia
Allkem Limited provides an Ore Reserve update for its Mt Cattlin operation in Western Australia. The Mt Cattlin Ore Reserve estimate is based on an updated Mineral Resource Estimate released on 17 April 2023. The Mineral Resource was updated after the completion of a major infill drilling program which successfully upgraded Inferred Mineral Resources. The Company has developed its internal systems and controls to maintain JORC compliance in all external reporting, including the preparation of all reported data by Competent Persons who are members of the Australian Institute of Mining and Metallurgy or a 'Recognised Professional Organisation'. As set out above, the Mineral Resource and Ore Reserve statements included in this announcement were reviewed by suitably qualified Competent Persons prior to their inclusion, in the form and context announced. This Release does not constitute or form part of any offer, invitation, solicitation or recommendation to acquire, purchase, subscribe for, sell or otherwise dispose of, or issue, any Shares or any other financial product. Further, this Release does not constitute financial product, investment advice (nor tax, accounting or legal advice) or recommendation, nor shall it or any part of it or the fact of its distribution form the basis of, or be relied on in connection with, any contract or investment decision. Technical information relating to the Company's Mt Cattlin project contained in this release is derived from, and in some instances is an extract from, the technical report entitled "Mt Cattlin Stage 4 Expansion Project" (Technical Report) which has been reviewed and approved by Albert Thamm, F.Aus.IMM (who is an employee of Galaxy Resources Pty. Ltd) as it relates to geology, drilling, sampling, exploration, QA/QC and mineral resources and Daniel Donald F.Aus. IMM (an employee of Entech Pty Ltd) as it relates to mining methods, Ore Reserves, site infrastructure, capital cost, operating cost estimates, mining cost, financial modelling and economic analysis in accordance with National Instrument 43-101 - Standards for Disclosure for Mineral Projects. In 1989 Pancontinental Mining, Limited drilled 101 RC drill holes. In 1990 Pancontinental drilled a further 21 RC drill holes. In 1997 Greenstone Resources drilled 3 diamond holes and 38 RC holes, undertook soil sampling and metallurgical test work on bulk samples from the mine area. Last prior resource and update was 28. A summary of all information material to the November 2018 understanding of the exploration results including a tabulation of the following 2019-2022 drill collars information for all Material drill holes: New resource development collar information is presented in Appendices below. Where comprehensive reporting of all Exploration Results is not practicable, 2019-2022 Drilling representative reporting of both low and high Drill hole collars and relevant assay details are appended grades and/or widths should be practiced to below. Other substantive exploration data Fe2O3 is modelled with Li and Ta to determine the effect of deleterious chemistry and mineralogy at or near pegmatite. Other exploration data, if meaningful and contacts and rafts of surrounding country rock with pegmatite. material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk sample- size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminants substances. The major assumptions made, and Mineral The underlying Mineral Resource model was jointly developed by Resource model used for pit and stope independent consultant Mining Plus Pty Ltd. and Allkem Ltd. and Allkem Ltd. (see optimization (if appropriate). ASX release 17 April 2023). A dilution study was then carried out by consultant Orelogy Mine Consulting (Orelogy) to determine the appropriate methodology to create a diluted, regularised Mining Model that could be readily used in GMP software.
