Bayash
Bayash Project
Bayash tenement (15.6 km2) consists of 7 geographical
minute exploration blocks located on the territory of Ulan administrative district
of Eastern Kazakhstan Region and is in 25km to the south of the city of
Ust-Kamenogorsk the capital of the region and big industrial, mining and
metallurgical center. The nearest village Bayash Utepov is in 1 km to the
southeast from the site. The Bayash represents a vast terrain located on the
northern slopes of the Kalba mountains. The absolute elevations reach 400-600 m
with relative altitudes of 100-200 m. The climate in the area is sharply continental with long (almost 5 months)
and cold (up to -400C) winter and hot summer (up to +400C). Hydrographic network in the area represented by
the Sibinka River, the left-bank tributary of the Irtysh River.
The Tochka (“Bayash”) LCT pegmatites, were discovered in 1956 by V. Kascheyev during
the geological mapping of a scale 1:10,000 and prospects for tantalum and
tin). The name “Tochka” for pegmatites
was given after the name of a small village nearby. Later in 1992, the
Kazakhstan parliament changed the name of Tochka village to Bayash Utepov
(“Bayash”).
The Bayash LCT pegmatites are mainly associated
with the exocontact of granites with schists and strikes in the NW direction
with maximum dimensions of 8km (SE-NW) by 1200m (E-W) with a minimum thickness
of 500m. Several hundred pegmatite veins varying between 0.2 and 10 m in
thickness outcropped on the surface.
During the geological prospects and exploration
(1957-1990) rushed for tantalum and tin Soviet geologists concluded that Bayash
LCT pegmatites and altered host rocks zone represent a Supra-ore system that contains significant Li resources and other associated
rare elements such as Ta, Nb, Sn, Be, Rb and Cs with low erosion.
In September 2022 Dalares sampled three
historical channels at Bayash tenement: k-43, k-49 and k-160. The assay results of the channel samples
provided by Anzaplan in March 2023 confirm the fact of substantial lithium mineralization presence. The key summary:
ü 0.68% of Li2O over 1m interval in K-160;
ü 0,99% of Li2O over 1m interval in K-49.
Having
reviewed the historical data and assay results from 2022 channel sampling,
Dalares has defined the priority zone for further exploration –The Barrier
Zone (“albite-spodumene vein Bariernaya – as derived from the historical
geological reports). The Barrier Zone is associated with the massive
albite-spodumene vein (“Barriernaya” vein) laying within porphyry biotite
granites. In contrary to all other pegmatite veins, the Bariernaya Vein, occurrence-wise,
has NE strike of 160m length at the surface with NE dipping at 75o
and thickness of 4.5m (V.Kascheyev, 1957; P. Sinishin, A. Butko, 1959).
