Vanstar develops a geological model based on the Nelligan gold deposit and embarks on the acquisition of multiple mining prop...

In response to the findings of mining and exploration consultants
InnovExplo, Vanstar (TSX-V. VSR) is pleased to announce the launch
of a selection process to acquire a number of mining exploration
projects in Quebec. The focus will be on areas deemed highly
favorable, with similar characteristics to the notable Nelligan
gold deposit located in the Chapais-Chibougamau region.
In 2019, the Nelligan gold deposit was the
subject of an initial mineral resource estimate and a joint IAMGOLD
- Vanstar NI 43-101 Technical Report documenting inferred resources
totaling nearly 3.2 million ounces of gold for almost 100 million
metric tons (see news release dated October 22, 2019). The current
work on Nelligan aims to reclassify the resource as the specified
category and to verify the depth extensions and extensions to the
west of the deposit.
Following the NI 43-101 report, Vanstar
commissioned InnovExplo to target favorable regions across the
Abitibi geological subprovince for disseminated gold deposits
hosted by metasedimentary rocks (Nelligan-type gold
mineralization).
Nelligan gold mineralization is clearly distinct
from most Abitibi tardi-orogenic gold deposits (i.e. distinct from
conventional shear zones and quartz-carbonate veins). Nelligan is
characterized by widespread and pervasive silica alteration and
disseminated gold mineralization with a low pyrite content (1–5%)
hosted in the metasedimentary rocks of the Archean Caopatina
Formation. Nelligan's geological context and mineralization style
is unusual when compared with other Abitibi gold deposits, but has
several similarities (and some differences) with the Canadian
Malartic style or even with Carlin-type mineralized systems.
In order to select potential new sectors at a
regional level, the approach used also drew on key features such
as:
- geological characteristics specific to the Nelligan
deposit;
- the presence of large sedimentary basins;
- local and regional structural elements;
- the spatial relationship with syntectonic intrusions;
- the metamorphic gradient;
- the metal association;
- the magnetic signatures.
Based on these specifications, Vanstar has
map-staked an initial group of 35 cells over an area of
approximately 1982 hectares—the Félix Project—and another block of
40 cells in an area of approximately 2264 hectares — the Amanda
Project. The latter was purchased from three independent
prospectors for a total of $60,000 and the issuance of 470,000
common shares. The sellers did not receive any royalties (NSR or
otherwise). The company plans to use map staking to increase the
number of cells for each of these projects.
The Félix Project
The Félix Project is based in the Chicobi Basin,
northeast of the municipality of La Sarre, Abitibi. To date, very
few boreholes have been made for this project. The majority of
those that have been completed are in the northern part of the
project to test iron formation. However, borehole 728-06-01 (GM
33270) intersected a sedimentary sequence in contact with the iron
formation that contained several anomalous gold values.
The company plans to carry out a geological and
geophysical survey here early next spring.
The Amanda Project
The Amanda Project is based in Jamésie and
contains several gold showings. Historic data has made it possible
to trace several gold showings for this project, including the
Arianne, Ti-Beu, Rock’n Hammer, La Mire and Kog-1 showings. Some
drilling conducted by Virginia Mines in the late 1990s also allowed
for the cross-cutting of different gold structures containing
significant gold values. This included the AC-97-31 drill hole,
which revealed 2.42 g/t Au over 4 meters and
5.40 g/t Au over 7 meters with 12.1 g/t Au
over 3 meters (GM 55430).
The geology of the Amanda sector can be
summarized as a sedimentary stack located in the heart of a large
fold, bordered by volcanic rocks. The sedimentary sequence consists
of wackes, iron formations and local
conglomerates. There are also shear zones, major
flaws and folds in this environment.
The Amanda Project rocks have undergone two
major stages of deformation. This project is also characterized by
the presence of a large fold forming a complex structural pattern.
The combined effect of these two folding stages is to multiply the
different lithostratigraphic units.
A combined geological and geophysical mandate
will be awarded to an external consultant in order to determine the
various targets for next summer.
Several other proposed targets are currently
under consideration. Some of these targets will be map staked over
the next few weeks. The company's management prioritizes sectors in
regions with as few constraints as possible.
The company intends to join forces with
potential partners seeking new ideas and/or create a subsidiary
that could test this new conceptual approach.
