Chesterfield drills high-grade gold-silver intercepts in Cyprus
establishing the discovery of a significant mineralised system
Chesterfield Resources is pleased to report assay returns from recent diamond
drilling that has established the discovery of a significant gold-mineralised
system in the Westline target at its Cyprus Troodos West project.
· Thick and locally high-grade gold intersections from recent drilling
provides evidence of a significant gold-enriched mineralized system so far
covering approximately 220m by 300m in area, and open on three sides.
· Highlights of assay returns include: 21.4 meters grading 1.75g/t
gold, (from 98.7 metres, downhole), and within this a high-grade zone of 3.3
metres grading 6.55g/t gold and 90.35 g/t silver (from 100.20 meters,
downhole), in drill hole 21WL03.
· Preliminary* results from a nearby hole 21WL02 include 0.82g/t gold
over 10.15 metres (from 96.00 meters), including 1.34g/t gold over 5.75 metres
(from 100.40 meters, downhole).
· This programme's drilling was testing for an extension of a
gold-mineralized zone that was identified through compilation of archive work
and nearby historic drilling. In combination, 15 contiguous drill holes
outline a continuous, thick, shallowly dipping and tabular body of gold
mineralization, that is also strongly anomalous in copper and zinc.
· The most recent hole, 21WL03, which was drilled by Chesterfield as
part of this year's drill campaign, has recorded the thickest and
highest-grade intersections to date, suggesting that the body is increasing in
size and grade towards the south.
· A test work programme of detailed geophysics and further step-out
drilling is planned with the focus of enlarging this continuous zone of gold
mineralization and exploring for higher gold-silver grades and possible zones
of copper-zinc enrichment.
· Graphics of the system and drilling will be posted on the company
website today
Said Chesterfield Director Dave Cliff "As part of our detailed compilation and
evaluation of historic drill results a continuous body of gold-enriched
mineralization was identified as a prospective target for this year's
drilling. The results of our step-out drilling were successful in
demonstrating both the thick and continuous nature of this mineralized body as
well as the potential for higher grades. Our results, when integrated with
historic drilling and other targeting data, indicate exciting potential for
the currently-identified mineralized body to further thicken, develop enhanced
gold and silver contents, and possibly zone into copper-zinc massive
sulphides. This is an exciting target which we will be focussed on advancing
in our next field programme." Dave Cliff was previously Head of Exploration
Europe for Rio Tinto.
In all, 15 drill holes have been drilled at Westline, including 13in previous
campaigns by Chesterfield and Northern Lion and two holes drilled by
Chesterfield in this year's programme. 14 holes have intersected this
gold-silver mineralized body, including 14.15m grading 2.12g/t gold from 89.90
meters in historic drill hole MVDD13-02 and 10.45m grading 3.83g/t gold from
100.00 meters in 18MV06. This season's drill hole 21WL03 is the most southerly
hole drilled so far at the Westline prospect and has the thickest intersection
to date. The drilled area, 220 metres by 300 metres is open to the south, east
and west, with the results to date indicate the south and southwest directions
to offer the most significant potential for thicker, higher grade
mineralisation.
The gold and silver mineralisation occurs within a stratabound zone of
brecciated and clay altered basalt. The mineralised body dips at a shallow
angle towards the southwest and it is interpreted that the reported
thicknesses are close to true thicknesses although specific work to assess
true thicknesses will be part of next drill campaign. The zone of alteration
and brecciation, which is tentatively interpreted to be hosted within a debris
flow preserved beneath a thick, impervious lava flow unit, also contains
anomalous copper and zinc values. Follow up analytical work is currently
being carried out by the technical team to determine vectors for concentrated
centres of copper-zinc but also additional gold-silver mineralisation.
Said Executive Chairman Martin French "The strong results from the hole 21WL03
is a game-changer for Westline. They indicate that the body is getting thicker
and higher grade to the South-East where it is open, and indicate that there
is much more to be found at Westline. The 3.3 metre intersection grading
7.7g/t gold equivalent(1) is particularly encouraging from a mining point of
view. This includes a 1.5 metre section of 11g/t gold equivalent(2).
We believe this could be part of a larger deposit with more metal-rich
concentrations. Our technical team is now designing a detailed follow up
programme, including geophysics, and additional drill holes to further test
and develop this mineralized body.

About Chesterfield Resources
Chesterfield Resources is a copper focussed exploration company centred around
a newly-acquired large exploration project in Labrador Canada, together with
its existing project in Cyprus.
The exploration technical team is led by two highly experienced industry
geologists Neil O'Brien, formally SVP Exploration & New Business
Development, Lundin Mining, and Dave Cliff, previously Head of Exploration
Europe, Rio Tinto.
The company has also acquired a major backer. In December 2020, Polymetal
International, the FTSE100 mining group, made a 23% investment in
Chesterfield via a placing of new shares, as strategic backing for the
company's project in Cyprus.
In Canada, the Adeline copper project is located within the western half of
the Central Mineral Belt, a 260 km long metal-rich belt located in Central
Labrador, eastern Canada. The Adeline property is comprised of five contiguous
mineral licenses totalling 29,725 ha (297.3 km2), covering the full extent of
the Seal Lake basin, an approximate 40km long by 10 km wide geological
structure which contains some 250 copper prospects. The project is close to
the regional service hub of Goose Bay.
The Seal Lake basin has seen extensive regional exploration over the years
resulting in a rich exploration database. Trenching and channel sampling has
established the presence of laterally continuous high-grade copper beds.
However there has been relatively little drill testing, largely due to the
lack of road access. Where sulphide mineralisation becomes more concentrated
the grades are extremely high, commonly 10-30% Cu due to the high tenor of the
principal copper minerals, chalcocite and bornite.
The company has recently completed the compilation and re-analysis of all
historic regional exploration datasets with the latest geophysical modelling
and visualisation software tools. It has assembled a team of expert
consultants who have decades of experience in this belt.
An initial field season, which has just been completed, focussed on both
previously identified, as well as new prospect areas. This is expected to
generate a significant pipeline of quality drill targets to test for
significant extents of bedded copper-silver mineralisation. The company is
currently progressing project planning and permitting applications.
In Cyprus the company holds the largest mineral exploration licence area of
any operator on the island.
Cyprus is regarded as a prospective copper-zinc-gold-silver exploration
location. It is a member of the EU, and its legal system is based on English
common law. Chesterfield identified a value-creative exploration opportunity
due to minimal exploration activity on the island in the last 46 years since
the invasion by Turkey in 1974 that put a halt to what had been a very
active mining industry.
While copper is the main exploration target, it is noteworthy that gold was
not historically exploited in Cyprus. Gold has been encountered in several
locations in the exploration target area and is an important part of the
exploration objective. This also includes a waste dump opportunity that will
be appraised, called Limni South Gold and an encouraging, potentially enlarged
mineralised zone described above.
The company announced high grade polymetallic results from its 2020 drilling
campaign and embarked in 2021 on an enlarged integrated geophysics, percussion
and diamond drilling exploration campaign. The company has now completed its
diamond drilling campaign for 2021 and has reported a significant gold
mineralised system at its Westline target. In addition, the company has
recently identified a new gold oxide project name Limni South Gold, based upon
encouraging samples at a waste dump as well as drilling in the vicinity, with
a programme of further test work being planned.
Chesterfield Resources is committed to world-class environmental standards in
all of its operations that are focussed on the exploration for copper, which
is an essential metal to developing clean technology projects worldwide. The
company hopes to develop industry and opportunities for the benefit of Canada
and the Republic of Cyprus.
