Hastings Technology Metals Limited (ASX: HAS) has announced high-grade drill results including 1m @ 1.56% TREO from 53m at the Yangibana deposit within its Yangibana Rare Earths Project in Western Australia. The company said that the drilling extended mineralisation at depth which remains open.
High-grade intersections from Yangibana included 1m @ 1.56% TREO from 53m; 2m @ 1.19% TREO from 76m; and 6m @ 0.81% TREO from 66m.
HAS noted that 34 out of the 35 holes drilled intersected mineralisation above the TREO lower cut-off. The company said that the results demonstrate geological continuity of grades at depth along the entire 1,000m of strike covered by the drilling.
The company reported that the Yangibana deposit assay results will be included into the overall Yangibana Project Mineral Resource Estimate upgrade due this Quarter.
The Yangibana deposit sits within a 20km-long corridor of rare earths mineralisation that is well defined and under explored. It has a JORC Mineral Resource of 1.95Mt @ 0.88% TREO, with 48% of the TREO reported as neodymium and praseodymium – underscoring the high value, world-class geology at Yangibana.
2020 exploration drilling program
The company had commenced the 2020 Exploration Drilling Program across the Yangibana Rare Earths Project with a Reverse Circulation (RC) drilling rig mobilised to site in mid-June last year.
The program was completed in the December 2020 Quarter and designed to achieve three goals – validate the existing Bald Hill Deposit Mineral Resource Estimates with close-spaced grade-control drilling; increase the Yangibana Project’s Measured and Indicated Mineral Resource; and obtain core samples for additional metallurgical test work and ore characterisation studies.
High-grade results from Yangibana
The company said that the infill drilling program at Yangibana was designed to plug existing gaps and test extensions to the Mineral Resource model at depth.
HAS said that at the Yangibana deposit, 35 drill holes tested approximately 1,000m or 50% of the length of the currently defined open pit. The company said that 34 out of the 35 holes drilled intersected mineralisation above the TREO lower cut-off used in the Mineral Resource estimation process.
High-grade intersections from Yangibana included 1m @ 1.56% TREO from 53m; 2m @ 1.19% TREO from 76m; 7m @ 1.10% TREO from 74m; 3m @ 0.96% TREO from 95m; and 6m @ 0.81% TREO from 66m.
Significant results from Yangibana drilling are as shown below.
The company said that the results confirm that mineralisation remains open at depth, with the deepest hole intersecting the orebody some 100m vertically below surface.
The company said that the Yangibana deposit assay results will be included into the overall Yangibana Project Mineral Resource Estimate upgrade due this Quarter.
HAS said that further work will include infill, step out, and twin-hole drilling. The company said that this work will be designed to improve confidence in, and test potential extensions to the current resource estimates and to provide necessary sample material for additional and ongoing metallurgical studies.
Hastings Technology Metals Chief Operating Officer Andrew Reid said: “These drill results at the Yangibana deposit further demonstrate the scale and quality of the mineralised system, with width and grade continuity intersected along the entire 1km of strike that was tested. The Yangibana deposit sits within a much broader 20km-long rare earth structure across the broader Yangibana Project area that has significant additional potential.
Hastings has continued to demonstrate the exploration upside, both near-deposit and regionally, while at the same time progressing the well-funded development pathway at the Yangibana Project. As the Mineral Resources continue to grow, we are preparing for the start of early-stage construction activities.”
