Venus Metals Corporation Limited (ASX: VMC) has provided a further update on its Youanmi Lithium Project (VMC 100%). The company has completed a successful follow-up mapping and sampling field programme at its Deep South Prospect which delineated two new zones with outcropping LCT pegmatites, south from lithium-rich pegmatites reported previously.
Matt Hogan, MD of Venus commented: “These follow-up rock sampling results received are outstanding with up to 4.6% Li2O and expand the lithium-rich pegmatites over 300m x 200m into three known zones which potentially only represent a small section of the mineralized system in this poorly exposed area.”
The company has said that geological mapping shows three main zones of outcropping Lithium-rich pegmatite over a 300m x 200m area. Referred to as Central Zone (up to 4.5 %Li2O), East Zone (up to 4.6 %Li2O), and North Zone (up to 4.6 %Li2O), common areas of high lithium grade are associated with coarse grained petalite (LiAlSi4O10), a lithium mineral with similar composition to spodumene (LiAl(SiO3)2) and known to occur with spodumene in other lithium deposits in the region (e.g. Mt Holland).
The northerly trending Central Zone is interpreted to dip gently towards east with the orientation of the other two zones yet to be determined. The mapped LCT pegmatites correlate with broad geochemical anomalies for caesium (up to 10,591ppm Cs) and tin (up to 473ppm Sn), consistent with an extensive intrusive system.
The Deep South mineralization is shaping up as a significant new lithium find and exploration has been accelerated to better understand the dimensions of the pegmatites and map the distribution of lithium minerals within them.
Preparations are made for a reverse circulation drilling programme to test the depth extent of outcropping pegmatites and explore for additional LCT pegmatites below extensive areas of cover. outcrop of massive petalite at East Zone (sample 2309018; 3.62 %LiO2).
