Addressing yours from another list...
Yes, there is gold at Nemegosenda. The only report I have seen published was in one of the original documents from the Gulf Dominon surveys. In that report, they note but are cagey about the potential... They found and reported a grab sample taken from outcrop (I think) with "high values" (and, that's a high value in relation to the 1950's standards... which means ounces per ton then, versus grams per ton today). But, that sample wasn't considered to be relevant in relation to their niobium exploration effort, because it was reported to be found in a carbonate sample... which also had significantly elevated values in REE... but essentially no niobium.
With MCP declaring BK last week... with Mountain Pass pretty much looking like toast... we're probably getting closer, more rapidly now, to the point where REE become worth talking about again... I could think of worse things than having REE values contaminated with gold at the ounce per ton level ? LOL!
Otherwise, it is a "known" that the structures produced by the regional carbonitites intrusions are gold bearing. REE market competitor Geomega was a spin out from Nio-Gold... who owned the carbonitite properties GeoMega holds now because they checking them for gold. The gold values found in that carbonitite were pretty well characterized, but weren't higher grade values, and they were considered too diffuse to be economic... and, they were also apparently not closely associated with the same rocks as the niobium and REE values...
Nemegosenda might be different than those deposits... because of the post-deposition timing of the intrusion of the syenite core... which might have had impact in driving significant hydrothermal activity which might have melted, mobilized and re-deposited pre-existing gold... including even that it could have been the same events as were the driver of the deposition of the Borden Lake deposits ? Don't remember the relationship in the timelines in the sequences they've posited there, right now...
But, it seems possible, at least, that the chemistry of the carbonitite rocks at Nemegosenda could have enabled enhanced deposition of gold along the southern boundary of contact between Nemegosenda's high pH rocks and hydrothermal fluids... which wouldn't tend to cause gold deposits to happen there if the gold were already in place there first... but might if the gold that was there already was remobilized and redeposited at the same time the syenite core was intruded ?
It's all speculation until you can show more than has been shown about the deposition model that is known to have generated high value gold inside the carbonitite...
So, will the gold potential at Nemegosenda... be allocated to Shining Tree... or to Nio-star ? |
