Improved Production for
Second
Quarter of
2023
Serabi Gold plc (AIM:SRB, TSX:SBI), the
Brazilian-focused gold mining and development company,
is pleased to report
operational results for the
second quarter of
2023 and provide
a review of its development and exploration
activities.
HIGHLIGHTS
- Second quarter
gold production totalled 8,518 ounces, a 6% improvement on the
first quarter in 2023.
- Mined grades
were 6.94 g/t gold, the highest since the third quarter of 2021.
Mined grades at Palito averaged 6.68 g/t gold.
- Coringa mine
development continued to progress well with mined grades of 7.83
g/t gold. The development ore transported to Palito plant
contributed over 2,000 ounces of gold production for the
quarter.
- The Vale
Exploration Alliance is progressing well with 7 diamond drillholes
for 3,200 metres completed at the Matilda prospect. A number of
other regional targets have also tested with total drilling
exceeding 5,500 metres. Assay results from Matilda and the other
targets are anticipated within the coming weeks.
- Cash held at 30
June 2023 was US$13.3 million (US$12.3 million net of cash held
under the Vale Exploration Alliance) compared to US$7.2 million at
31 December 2022.
Mike Hodgson, CEO of Serabi,
commented:
“An excellent second quarter to follow the first
quarter production of 8,005 ounces, keeps the company on course to
meet its guidance for this year of between 33,500 to 35,000
ounces.
“The quarter saw improved grades coming from
Palito, along with continued high grade development ore from
Coringa, which resulted in a plant feed grade of 6.84g/t gold,
which we have not achieved since the third quarter of 2021.
“Mine development at Coringa continued to be
very successful. The payability of the development is quite
remarkable, with very limited low-grade or waste zones being
encountered as the orebody is developed. The mine is still in
development and only operating under the GUIA trial mining license.
Even so, the small volumes of ore that are being extracted and
transported to the Palito plant are proving to be very beneficial,
with over 2,000 ounces of gold production attributed to Coringa in
the second quarter.
“On the exploration front, the relationship with
Vale is working well and the first phase of drilling was completed
on the Matilda copper porphyry prospect with seven holes now
drilled. Samples have gone for multi-element external assaying, and
we eagerly await the results. With three rigs on site, the focus
has shifted to other regional targets with a second round of
drilling planned at Matilda when the assays from phase 1 have been
received and the geological picture updated.
“Management remains hopeful that we are entering
the final stages of satisfying the requests of the court and public
prosecutor regarding the future licencing of Coringa and in
particular that the project presents minimal impact to the
environment and communities that live nearby. The indigenous study
report (“ECI”) was completed in April. It has been circulated
through the technical committees of the Indigenous communities with
comments received and being incorporated into a revised draft. In
parallel, independent consultations have been carried out with the
indigenous communities to seek project support, which have
progressed very well. With the demands fulfilled, this should
result in a cancellation of the court decision and open the door
for SEMAS, the environmental agency, to issue the installation
License (“LI”) shortly thereafter.”
OPERATIONAL
RESULTS
Total production for the second quarter of 2023
was 8,518 ounces. Coringa contributed 2,186 ounces to this total.
Total ore mined from the Palito Complex during
the quarter was 31,652 tonnes at 6.68 g/t compared to 29,691 tonnes
at 6.33 g/t of gold for the first quarter of 2023. Development
mining operations at Coringa generated a total of 9,370 tonnes at
7.83 g/t in the quarter.
41,116 tonnes of ROM ore was processed through
the Palito plant during the quarter, with an average grade of 6.84
g/t of gold, compared with 39,004 tonnes at 6.75 g/t in the first
quarter of 2023. This included 9,215 tonnes of Coringa ore at a
feed grade of 7.59 g/t gold.
A total of 2,469 metres of horizontal
development has been completed at Palito during the quarter, of
which 1,619 metres was ore development. The balance is the ramp,
cross cuts and stope preparation development. Horizontal
development at Coringa totalled 508 metres, of which 304 metres was
in ore.

EXPLORATION UPDATE
The Vale Exploration Alliance, signed in May
2023, is progressing well with exploration activity across a number
of key target areas of the Palito tenement package. This activity
includes:
- Three contractor diamond drill rigs
in operation having completed a total of 21 holes, 7 of which were
testing the Matilda copper porphyry target. The total metres
drilled now exceeds 5,500 metres of the planned 15,000 metres
programme.
- Samples have been sent to an
independent laboratory for multi-element assays with the initial
results from Matilda expected within the coming weeks.
- Systematic soil sampling and auger
drilling is being undertaken on areas not previously tested. Soils
are being initially tested with a hand-held XRF (X-ray
fluorescence) and delivering some interesting results. Following
the receipt of results from the external laboratory, further
mapping activities and a drilling programme will be
considered.
The initial phase of drilling at Matilda was
designed to test the footprint of the target. Logging of the core
suggests that a number of the holes intersected mineralisation
similar to that identified in the 2022 programme. Other holes
appear to be more weakly mineralised whilst two holes returned
broad zones with what visually appears to be higher grade
mineralisation, comparable with the highest grade zones from the
2022 programme where grades of 0.4% to 0.7% copper equivalent were
intersected (see press release dated 5 July 2022). Assay results
from an independent laboratory are awaited and will be announced in
due course. Following full geological analysis of these assay
results, a second phase of drilling will commence at Matilda. This
will also be guided by a ground geophysics survey that has been
programmed to support further geological interpretation.
The drill rigs have moved to other targets
including:
- Barbara and Maria Loura which are
potential extensions of or parallel structures to the Sao Chico ore
body.
- Cinderella which is the site of
major historic artisanal activity and has a strong gold-in-soil
anomaly over a broad area.
- Calico, which is a target of
comparable size to Matilda with a strong gold-in-soil anomaly but
no historic drilling.
The regional exploration effort of soil sampling
and auger drilling has been successful in identifying a number of
new high priority targets using a hand-held XRF device to generate
preliminary results while external assays are pending. These
targets include a significant copper-in-soil anomaly to the north
of Matilda that will require follow-up mapping and potentially
drilling later in the programme. With 1,450 soil samples collected
and 308 auger drillholes completed, these programmes are 53% and
72% completed respectively.
FINANCE UPDATE
Cash balances at the end of June 2023 were
US$13.3 million which includes US$0.94 million of funds held for
the Vale Exploration Alliance. This compares with a cash balance of
US$7.2 million at the end of December 2022 and US$13.9 million at
31 March 2023, which included a US$5.0 million loan for a 12 month
period from Santander Bank in Brazil received at the end of
February 2023. During May 2023, the Group repaid the US$5.0
million loan facility that it had taken out with Itau BBA bank in
May 2022. Net cash attributable to the Group has increased by
US$5.1 million during the first six months of the year.
The person who arranged for the release of this
announcement on behalf of the Company was Clive Line, Director.

Assay ResultsAssay results reported within this
release include those provided by the Company's own on-site
laboratory facilities at Palito and have not yet been independently
verified. Serabi closely monitors the performance of its own
facility against results from independent laboratory analysis for
quality control purpose. As a matter of normal practice, the
Company sends duplicate samples derived from a variety of the
Company's activities to accredited laboratory facilities for
independent verification. Since mid-2019, over 10,000 exploration
drill core samples have been assayed at both the Palito laboratory
and certified external laboratory, in most cases the ALS laboratory
in Belo Horizonte, Brazil. When comparing significant assays with
grades exceeding 1 g/t gold, comparison between Palito versus
external results record an average over-estimation by the Palito
laboratory of 6.7% over this period. Based on the results of this
work, the Company's management are satisfied that the Company's own
facility shows sufficiently good correlation with independent
laboratory facilities for exploration drill samples. The Company
would expect that in the preparation of any future independent
Reserve/Resource statement undertaken in compliance with a
recognised standard, the independent authors of such a statement
would not use Palito assay results without sufficient duplicates
from an appropriately certificated laboratory.
