Hastings Technology Metals Ltd. announced material increase in Mineral Resource Estimate at its Yangibana Rare Earths Project in Western Australia's Gascoyne region. The new Mineral Resource estimate is the result of a successful 23,739m drilling campaign at Yangibana during 2020 targeting additional rare earth mineralisation plus the previously announced Mineral Resources. Additional holes were also drilled to provide samples for metallurgical test work and further define orebody grade control. Only 5 of Yangibana's 10 deposits were drilled in the 2020 campaign, with all of these deposits remaining open at depth and along strike. The 2020 drilling campaign increased the RC and Diamond drilled metres dataset by 39%. The updated Yangibana Mineral Resource has been completed on the Bald Hill, Simon's Find, Frasers, Auer and Yangibana deposits and is reported in addition to the previously announced (October 2019) but unchanged deposits of Yangibana North West, Kane's Gossan, Gossan, Lion's Ear and Hook. Total Mineral Resources at the Yangibana project now stand at 27.42Mt @ 0.97% TREO. Measured and Indicated tonnes for deposits drilled during 2020 increased by 54% to 16.3Mt with a corresponding 32% increase in total rare earth oxides (TREO) to 137kt. The increase in Mineral Resources is a combination of drilling completed during 2020 and application of a cut-off grade at 0.24% TREO following evaluation of processing costs and forward rare earth pricing assumptions, which will be released in the upcoming Ore Reserve statement. Mineral Resources for Yangibana North West and additional Inferred Mineral Resources from Gossan, Kane's Gossan, Lion's Ear and Hook remain unchanged from 2019 and are stated at a 0.20% NdPr cut-off. It is expected that re-stating these resources to a 0.24% TREO cut-off will further increase the total Mineral Resources for the Yangibana project. All Yangibana project deposits start from surface, with no overburden and contain large coherent domains comprising mostly high-value rare earths dominated mineral assemblage. Hastings intends to continue to progress additional drilling programs across all Yangibana deposits in due course. Hastings' is currently focussed on updating Ore Reserves from the updated Mineral Resources targeting extensions to Yangibana's proposed mine life of high-grade NdPr concentrate production beyond the current defined 13 years. The work undertaken to re-estimate the deposits was completed by Dave Princep from Gill Lane Consulting and incorporates all of the information and data that was used in the previous Mineral Resource estimate plus the 2020 drill program data which was released to the ASX on the following dates; 18 June 2020, 17 September 2020 and 12 October 2020 and 21 January 2021, 8 February 2021, 26 February 2021 and the 15 March 2021. This update has added 37% tonnes and 19% TREO metal to the total Measured and Indicated Mineral Resources and 31% tonnes and 14% TREO metal to the total Mineral Resources for all deposits within the Yangibana project. Hastings completed an extensive drill program during 2020 comprising 341 holes for 23,739m of reverse circulation and 46 holes for 1,605m of diamond drilling. Holes were initially drilled at 40m spacings along strike and down dip. Infill drilling in areas with Mineral Resource potential has been undertaken at spacings of 37.5m or less. Drillholes were predominantly vertical, subject to access availability, with holes into the steeper mineralized zones (Auer, the southeastern portion of Fraser's, Bald Hill and Yangibana) being at -60o or - 70o. Internal downhole surveys were carried out at 30m intervals downhole by the drilling contractors using a Reflex electronic single-shot camera within a stainless-steel drill rod. Collar surveys were carried out and collected by RM Surveyors using DGPS utilising a locally established control point. Accuracies of the drillhole collar locations collected by RM Surveyors is better than 0.1m. Downhole density data was collected on a large suite of holes utilising a Geovista FDSB-4620 downhole density tool on a continual basis giving 1cm data resolution. RC holes were drilled using a nominal 5¼ inch diameter face-sampling bit. Samples were collected through a built- in cyclone with a triple-tier riffle-splitting system providing a large sample of approximately 25kg and a sub-sample of 2-4kg from each metre drilled, of which selected samples were sent for analysis, from each metre drilled.
