Miramar Resources Spots Lang Well lithium and REE Potential
THE DRILL SERGEANT: Miramar Resources (ASX: M2R) completed a review of historic and government open file data for the company’s 100 per cent-owned Lang Well project in the Murchison region of Western Australia.
Miramar Resources reported the review has highlighted multiple pegmatite occurrences indicating the potential for rare earth element (REE) and/or lithium mineralisation at the project.
Information extracted by the company from Geological Survey of Western Australia datasets revealed at least 50 mapped pegmatite occurrences within the Lang Well project, including outcropping pegmatites hitting over at least seven kilometres of strike in the northern half of the project.
The pegmatites occur in a sequence of granitic gneiss and mafic amphibolite that has been intruded by later Proterozoic dolerite dykes.
Lang Well has seen little exploration, with the only activity of note comprising an auger sampling program in 2009, samples from which were only analysed for a limited suite of elements.
Given the dates associated, there is little surprise there has been no recorded analysis of REEs or lithium for any of the pegmatite occurrences or the auger sampling.
Interestingly enough, the auger sampling was followed up by a 35 hole aircore program in 2010 across three lines, two of which are outside the current project tenement.
Inside the project, hole BADAC33 intersected anomalous REEs, including 4m at 0.15 per cent Total Rare Earth Oxides (TREO).
Holes 50m either side also encountered anomalous REEs.
“The Lang Well project covers a very large area with only about 20 per cent outcrop,” Miramar Resources executive chairman Allan Kelly said in the company’s ASX announcement.
“Most of the 50 recorded pegmatite occurrences occur in the outcropping area in the north whereas the single historical aircore traverse intersected anomalous REEs in an area of transported cover in the south east.
“We think it is highly likely therefore, that there is potential for a significant number of other pegmatite occurrences either outcropping or below shallow cover.”
Miramar signalled it would complete soil and rock chip sampling across the northern pegmatite trend and is planning a detailed drone magnetic survey over the south-eastern portion of the tenement to aid with an upcoming aircore drilling program that will test the auger gold anomalism.
