Dr.
Kerim Sener, Managing Director, commented:
"This announcement marks the completion of our technical
assessment of the due diligence drilling programme of the Dokwe
Gold Project, following more than six months of detailed work on
site by our team. We have been able to both confirm historical
drilling results, the distribution and nature of gold
mineralisation within the Dokwe North and Central deposits and
their geological controls, including new insights into the
structural controls on mineralisation. The results from the holes
at Dokwe Central in particular are critical for us to estimate
resources at this deposit, and the three holes we have assays for
so far have yielded lengthy zones of high and moderate-grade gold
mineralisation.
"We are now in the closing stages of our technical programme,
with work on the revised Mineral Resource Estimate for both Dokwe
North and Dokwe Central well underway. We are looking forward to
announcing the new estimate in the coming weeks, in advance of the
General Meeting to approve the Merger with
Rockover."
About the Dokwe Project
The Dokwe North and Dokwe Central
gold deposits are located 2km apart ("Dokwe" or "Dokwe Project")
and are situated in the Tsholotsho District, 110km WNW of Bulawayo,
Zimbabwe (Figure 1).
Bulawayo is the second largest city in Zimbabwe (population:
660,000) with excellent road, rail and air links to the rest of the
country and internationally, and represents significant mining
services and educational centre, hosting both the Zimbabwe School
of Mines and the National University of Science and
Technology.
The Dokwe Project was discovered by
Rockover in 2002, utilising innovative soil geochemical exploration
methods capable of detecting mineralisation beneath cover, and
subsequently drill-tested for the first time in 2004.
It represents the largest undeveloped gold project
in Zimbabwe and is currently owned by Rockover in which Ariana
currently holds circa 2.1%.
Due
Diligence Work Completed
The primary objective of the DD
programme was to evaluate the nature and grades of mineralisation
documented in both Dokwe North and Central, build detailed
geological models using multi-element geochemistry to define key
lithologies and estimate the Mineral Resources with the support of
more robust geological models. This work
included:
Between November 2023 and May 2024,
the Ariana team has undertaken the following:
·
Re-organisation and re-formatting of all historic
databases.
·
Re-logging and portable X-ray Fluorescence (pXRF)
analysis of 21,662 metres of drill core to provide representative
multi-element geochemistry of lithologies.
·
Completion of 1,222 metres of diamond drilling
(612 metres Dokwe North and 610 metres Dokwe Central).
·
Laboratory fire assay analysis for gold, for 610
metres of drill core (DPD129, DPD130 and DPD131), one further hole
pending.
·
A full review of historic resources and the
estimation methods employed.
·
Collection and evaluation of 426 detailed
structural measurements from orientated drill core.
·
An evaluation of historic specific gravity data
and the collection of 158 new density check readings spanning all
major lithologies within Dokwe North and Dokwe Central.
Summary of Drilling
Four oriented diamond drill holes
were drilled by Ariana during the DD period (Figure 1). Two holes (DPD129 and
DPD130) were designed to test the Dokwe North deposit. The
remaining two holes (DPD131 and DPD132), were planned to validate
mineralisation at Dokwe Central. Drill holes within Ariana's
programme were dominantly drilled using standard HQ drill rods.
However, some holes were collared with PQ-sized rods to
approximately 100m. Deeper holes (>250 metres), were drilled to
final depth using NQ rods after HQ (DPD132).

North and Central showing the outline of the designed
pre-feasibility pit for Dokwe North and the optimised pit (not
included in the pre-feasibility) for Dokwe Central. The 2023-2024
due diligence drilling collars are also shown in
magenta.
Assay results have been received for
three of the drill holes (DPD129, DPD130 and DPD131). DPD129 was
drilled into the central area of the Dokwe North deposit, and was
designed as a twin hole of historical hole DPD49, a
well-mineralised hole containing representative mineralisation of
the transitional and sulphide zones within the deposit. DPD129 was
collared approximately 5m northeast of DPD49, and successfully
tested all major zones of mineralisation documented within the
historical hole. Overall, DPD129 returned somewhat higher grades
than the historical hole, the main zone providing
45m @ 2.75g/t Au from 86m, which includes 15m @
4.55g/t Au from 86m, and 12.1m @ 4.15g/t Au from 104.9m, announced
on
AIM: 9 May 2024. DPD129 is considered
to have adequately confirmed the results from DPD49.
Figure 2: Northwest-southeast
cross-section through DPD129 and DPD49. DPD129 is a near-perfect
twin of DPD49, and intercepted mineralised material where expected,
whilst never deviating more than 6m from DPD49.
DPD130 was designed to target the
high-grade northern end of Dokwe North, and test it to the base of
the 2022 optimisation pit, but drilled in the opposite direction
(NW to SE) to the majority of historic drilling to improve the
understanding of the structural controls on mineralisation. A total
of 127m of mineralisation was intercepted at various depths between
57m and 329m, with highlights being a best intercept of 14m @
4.44g/t Au from 247m, a shallow intercept of 6m @ 3.18g/t Au from
57m and the longest intercept of 23m @ 0.73g/t Au from
306m.
Drillhole DPD131 was Ariana's first
test hole into Dokwe Central, and was designed to provide
additional confidence to the 2011 Dokwe Central Mineral Resource by
infilling between historical holes at the base of the optimisation
pit (Figure 3). Once again
broad zones of mineralisation were intercepted, including 20m @
1.39g/t Au from 71m and 14m @ 1.68g/t Au from 100m, confirming
historical results.
DPD132 was an exploration hole,
currently being used for internal research to develop our
understanding the nature of the Dokwe Central mineralisation at
depth. Assay results from this hole are yet to be
receieved.

cross-section through Dokwe Central, primarily highlighting DPD131,
which was strategically planned to infill a gap in the historic
Mineral Resource model at the base of the optimisation
pit.
Table 1: Significant intercepts
from DPD129 to DPD131, with a minimum cut of 10 gramme x metres
gold. Results for DPD129 were originally announced by Ariana on the
9 May 2024, whilst those from DPD130 and DPD131 have not been
announced before. Intercepts are calculated using a 0.3g/t Au
cut-off and allowing for up to six metres internal dilution and
preserving shorter higher-grade intercepts where
applicable.

Summary of Portable XRF Analyses
A detailed pXRF and core logging
study of selected historic drillholes were completed. The study
includes 21,662 multi-element readings at
approximately 1m spacing over 37 drill holes. Results from the new
data have identified distinct chemical signatures for most of the
lithological units known to host mineralisation. This has added
significant confidence to the geometry of all major lithological
units within both Dokwe North and Central, and importantly defined
lithological boundaries very accurately. A further 25 holes are
currently being analysed by pXRF to provide additional information
on the peripheral extents of both deposits.
The pXRF work undertaken by the
Ariana and Rockover teams has generated a significant new
understanding of the mineralised systems of both deposits, their
geological settings, structural attributes and much more. A full
review of all data has now been completed, and the Ariana team is
well underway with a new Mineral Resource Estimate for both Dokwe
North and Dokwe Central in accordance with the JORC Code
(2012).
Sampling and Assaying Procedures
All diamond drill core is currently
being processed at the ISO-credited Antech Laboratory in Zimbabwe.
As part of Ariana's normal operational procedures, 10% of samples
are duplicated from spilt core and are being sent to a second
commercial laboratory (ALS Global in Johannesburg), for check
assay. Ariana is yet to receive the results of the check
assays.
Results are being assessed
systematically and are being grouped according to the individual
deposits drilled within the Dokwe Project area. PQ, HQ and NQ size
drill-core samples from the programme were cut in half, and then
half again for a quarter core sample. This was completed using a
core saw. Samples were sent for analysis in batches in line with
the Company's quality control procedures. In most cases,
three-quarters of the core remain in the archived core
trays.
For all the new drill holes, a total
of 635 samples (including 95 QA/QC samples) were submitted to the
Antech Laboratories. Core recovery for all drilling conducted at
the Dokwe Project during this campaign was 98.62% for a total of
545 measurements.
All samples were assayed for gold
using a 50g fire assay. Reviews of the assay results
have
determined that all Quality
Assurance and Quality Control samples (blanks, standards and
duplicates) passed the quality control checks established by the
Company, with duplicate samples showing excellent correlation.
Laboratory sample preparation, assaying procedures and chain of
custody are appropriately controlled. The Company maintains an
archive of core samples and a photographic record of all cores for
future reference.
