@Tragore - Sounds like a good plan but I hope they don't delay drilling. They have done well since starting and next step is the drill bit. Of course they need to find where to drill but the
"clear anomalies in portions of the trenches where pegmatites were observed" would be the starting points I guess.
@fooca - I have always maintained that expecting to use the new lab facility in Guyana was always too premature - I expect next year perhaps. The investment in the country is a good sign as I have alluded to before in an earlier post.
Just trying to make sense of their announcement further - the below all in my opinion
"Based on microprobe analysis from rocks taken from Phase 1 (analysed at Brasilia University) the pegmatites are albite-rich. These albite-rich pegmatites are possibly part of a larger zoned pegmatite system where the enriched Spodumene zone could be expected deeper in the rock package."
So what they say is:
1) The pegmatite/s is albite rich
2) It is a zoned pegmatite
Without being too technical - there are two main types of pegmatites, zoned and unzoned.
The unzoned type is far less complex and is of lesser economic significance because they contain only quartz, feldspar and mica crystals.
The zoned pegmatites have distinct layers which surround a central core, and have a consistent pattern of composition and relative crystal size within each layer. The following graphics/visuals act as a good reference for the zoned pegmatite (dyke shaped) which is a common form with distinct zoning. The outer wall is made of fine grained quartz mixed with other predominant minerals present in the parent mineral. Inside that is a wall zone which has more coarse grained feldspars and quartz.
So it looks like they have observed the albite and the albite zone is in the outer zone and close to the core where the spodumene is located. Now we need to drill to find the core zone - it's all the same for all pegmatites. This is how it evolves over time.
Also it is good they have mentioned shallow dipping (close to horizontal angle). The pegmatite takes shape with an angle close to the surface and not vertical so hence consequently better for open pit mining of course.
