RNS Number : 2287A Shanta Gold Limited 01 February 2022
1 February 2022
Shanta Gold Limited
("Shanta Gold", "Shanta" or the "Company")
Gold Reserves Mined in 2021 Replaced at New Luika Gold Mine
Year End 2021 NLGM Reserves & Resources Statement
Shanta Gold (AIM: SHG), the East Africa-focused gold producer, developer and
explorer, is pleased to announce a reserves and resources update for its
projects in Tanzania as at 31 December 2021.
Eric Zurrin, Chief Executive Officer, commented:
"Shanta has once again replaced all annually mined ounces in 2021 with new
reserves, as well as extending the mine life at New Luika Gold Mine to at
least the end of 2026. This marks the third consecutive year in which we have
replaced mined reserves across our portfolio through successful exploration
which remains key to unlocking long-term, sustainable returns for our
shareholders.
During 2021, we invested US$4.4 million in exploration, with the 31,600 metres
drilled in Tanzania returning 110,000 ounces of new reserves whilst also
expanding our regional resources outside of the New Luika mine plan. The
upgrading of approximately 80,000 oz grading 4.31 g/t to the Proven Reserve
category from Probable following grade control drilling also significantly
contributed to the de-risking of our 12-month production outlook.
Longevity across our prospective portfolio of mining and exploration licences
is a core value lever and we look forward to sharing our West Kenya resource
estimate at the end of February."
Highlights:
· 3rd consecutive year that all mined ounces have been replaced during
the year with newly defined reserves;
· Total JORC 2012 compliant gold reserves of 645,000 ounces ("oz")
grading 3.04 g/t across the Company's two projects in Tanzania, an increase of
20,000 oz net of depletion;
· Newly defined reserves of 110,000 oz added in 2021, before depletion,
predominantly from the Luika Underground project;
· A total of 80,000 oz, grading 4.31 g/t, have been upgraded from
Probable to Proven Reserves following grade control drilling de-risking the
12-month production outlook;
· Reserve-based mine life extended again, now to end of 2026 at NLGM
and unchanged to end of 2029 at Singida;
· Total resources of 2.01 million oz grading 2.40 g/t across both
projects in Tanzania (JORC 2012 compliant);
· No change in Singida reserves & resources;
· Updated West Kenya resource estimate expected at the end of February
2022.

Glossary of Technical Terms
"Au" chemical symbol for gold
"cut off grade" (COG) the lowest grade value that is included in a resource statement. It must
comply with JORC requirement 19: "reasonable prospects for eventual economic
extraction" the lowest grade, or quality, of mineralised material that
qualifies as economically mineable and available in a given deposit. It may
be defined on the basis of economic evaluation, or on physical or chemical
attributes that define an acceptable product specification
"g/t" grammes per tonne, equivalent to parts per million
"Inferred Resource" that part of a Mineral Resource for which tonnage, grade and mineral content
can be estimated with a low level of confidence. It is inferred from
geological evidence and assumed but not verified geological and/or grade
continuity. It is based on information gathered through appropriate
techniques from locations such as outcrops, trenches, pits, workings and drill
holes which may be limited or of uncertain quality and reliability
"Indicated Resource" that part of a Mineral Resource for which tonnage, densities, shape, physical
characteristics, grade and mineral content can be estimated with a reasonable
level of confidence. It is based on exploration, sampling and testing
information gathered through appropriate techniques from locations such as
outcrops, trenches, pits, workings and drill holes. The locations are too
widely or inappropriately spaced to confirm geological and/or grade continuity
but are spaced closely enough for continuity to be assumed
"JORC" The Australasian Joint Ore Reserves Committee Code for Reporting of
Exploration Results, Mineral Resources and Ore Reserves 2012 (the "JORC Code"
or "the Code"). The Code sets out minimum standards, recommendations and
guidelines for Public Reporting in Australasia of Exploration Results, Mineral
Resources and Ore Reserves
"koz" thousand troy ounces of gold
"Measured Resource" that part of a Mineral Resource for which tonnage, densities, shape, physical
characteristics, grade and mineral content can be estimated with a high level
of confidence. It is based on detailed and reliable exploration, sampling
and testing information gathered through appropriate techniques from locations
such as outcrops, trenches, pits, workings and drill holes. The locations
are spaced closely enough to confirm geological and grade continuity
"Mineral Resource" a concentration or occurrence of material of intrinsic economic interest in or
on the Earth's crust in such form, quality and quantity that there are
reasonable prospects for eventual economic extraction. The location,
quantity, grade, geological characteristics and continuity of a Mineral
Resource are known, estimated or interpreted from specific geological evidence
and knowledge. Mineral Resources are sub-divided, in order of increasing
geological confidence, into Inferred, Indicated and Measured categories when
reporting under JORC
"Mt" million tonnes
"oz" troy ounce (= 31.103477 grammes)
"Reserve" the economically mineable part of a Measured and/or Indicated Mineral Resource
