3) Central Intermediate Zone (CIZ)
|ORIENTATION (DEGREES)||LENGTH (M)||Li 2 0 (%)|
This zone is located in the upper portions of the pegmatite and consists of predominantly grey K-feldspar. Towards the southeast part of the pegmatite, the K-feldspar displays increasing alteration to a muscovite+quartz assemblage which locally is lepidolitic.
The Pakeagama Lake pegmatite does not currently have a resource, however the mineralogy of the 3 zones (UIZ, LIZ and CIZ) and the presence of SQUI as the dominant lithium mineral assemblage is similar to the mineralogical zonation of the Tanco pegmatite. The Tanco pegmatite is located southwest of Pakeagama Lake in southeastern Manitoba and was a lithium mineral concentrate producer from 1986 until operations were suspended in 2009. According to Giancola (2002), in 1992, Tanco’s lithium reserve grade was 2.71% Li 20.
“The lithium grades encountered from the program place the Pakeagama Lake pegmatite as a leading exploration target for rare metals. Furthermore, HLM anxiously anticipates the pending final results of analysis from the other elements that our pegmatite contains, such as Tantalum and Rubidium. With the data we have collected, the Company has identified targets whereby a Phase I, 1,000m diamond drilling program has been independently recommended“, said Trevor R. Walker, President of HLM.
