Lithium grades o just what makes for good hard rock lithium exploration results?
At the very early stages, most explorers use radiometric anomalies in addition to outcrops, as some of the minerals that occur in pegmatites give off a notable signature.
“If there are associated minerals such as tin and tantalum, which are heavy minerals that often stay in the soil proximal to the mineralisation, you may do soil sampling for lithium, but most just very quickly go to drilling,” Cowen said.
As for drilling Cowden noted that grades of about 1.6% lithium oxide, which are seen at Firefinch’s world-class Goulamina project in Mali, are pretty much the “gold standard”.
“It’s really hard to see grades much higher, you do get grades up in the twos and so forth, but the average grade, if it’s less than 1%, it’s going to struggle,” he explained.
“If it’s getting closer to 1.5% then it’s pretty interesting.

So at the average we showed, .95 is a bit on the low side for mining. I understand that this is our first recon holes and that it is great to find the asset. I will be excited to see what the future holds for all of us. This is an add-on value play for us.
