RE:RE:RE:Ceo.ca posters compare BRW to Harfang ($ 9 million mkt cap)There is lithium in spodumene.
Photos and text from BRW's website show and mention spodumene at Mirage. For those two reasons there must be lithium at Mirage.
The chemical formula for spodumene is Li[AlSi2O6], and the "Li" stands for lithium. The maximum amount (by weight) of lithium in spodumene is 8.03% - which you can calculate for yourself if you look up atomic weights and use the formula of for spodmene. One source on the web says that spodumene in run-of-mine typically contains 6-7% spodumene, partly because sometime atoms with similar radii and valence states replace Li in the mineral crystal.
Example: if a large mass of rock is 1/3 spodumene (that's a lot!), and the spodumene in it contains an average of 6% lithium, then the rock mass should have 2% lithium in it, on average. if there's a huge amount of it there's a good chance it'd be worth building a mine. Most mines that produce lithium from spodumene containe between 0.9% and 1.4% lithium in the mined rock.
