For those interested, reading RDT's 28 September 2021 announcement regarding Mt Ida throws up some intriguing points in comparison to MAN's Berinka. Extracted below is what I found most intriguing (note the reference to "pegmatite occurrences" and the context in which it is used):"Lithium Review on Mt Ida Dataset Whilst undertaking the technical due diligence of the Mt Ida Project, the Red Dirt technical team noted that multiple high-grade lithium intervals had been intersected within pegmatite bodies on the western contact of the main Mt Ida granite intrusive, known as the Copperfield Granite. The Company has identified to date 44 drill holes, from a total of 4,295 within the Mt Ida dataset, that have either been logged with pegmatite occurrences or have been assayed incidentally for Lithium as part of a multi-element analysis...Drill hole IDDD002 is an NQ diameter diamond hole drilled in November 2006. The hole intersected 23.3m of spodumene bearing pegmatite from 252.2m downhole and located in the immediate hanging wall of the Baldock copper/gold lode. This pegmatite core was never submitted for assay, let alone for Lithium or the rare earth mineral suite. The drill hole core has now been located and will be cut and submitted for assay this week. Interestingly, the interval of the Baldock lode targeted in IDDD002 and immediately downhole of the broad pegmatite intercept assayed very strongly for both copper and gold, namely 3.67m @ 2.88% Cu and 11.14 g/t Au. This copper/gold intercept lies outside the current Mt Ida gold resource. Initial investigations from available data shows pegmatite outcropping in 5 separate locations proximal to the main granitic intrusive, and along the contact with the western bounding mafic amphibolite units which host the high-grade Mt Ida gold copper lodes. A preliminary target corridor has been interpreted and extends for up to 5km in strike from the most southern-identified outcrop parallel to the granite and north into the Company’s adjacent exploration tenement, with potential to extend further in both directions. Of significance is that no historic exploration has been carried out with the intention of targeting these Lithium bearing pegmatite intrusives. This opens up large areas on both the eastern and western limbs of the granitic intrusive contacts for future exploration and will complement the Company’s aggressive gold/copper exploration program at the Mt Ida Project."

This is an important point - both your extracts make it. Granitic intrusions are prospective for gold as well. Surely they would test cores as well as do rock chip assays ?"Initial investigations from available data shows pegmatite outcropping in 5 separate locations proximal to the main granitic intrusive."
