Serval Resources Plc
(“Serval” or the “Company”)
Results from Geophysical Surveys on PL082 and PL231
in the Kalahari Copper Belt, Botswana
Serval Resources Plc (AIM: SRVL), a company focused on building an independent
copper and future metals developer, is pleased to announce the results of its
first geophysics programmes completed on Licence PL082/2020 (“PL082”) and
PL231/2018 (“PL231”) in the Kalahari Copper Belt (“KCB”), Botswana. This region
is considered one of the most prospective areas in the world for new sedimentary
copper discoveries (source: US Geological Survey).
Serval has identified the utilisation of a combination of geophysical techniques
as being key to exploration success in the KCB, where the geology of the
underlying copper mineralisation is overlain by sand cover of varying depths.
Highlights
· The surveys utilised a combination of three geophysical methods to provide
insight into the thickness of the sand cover overlying the target Kalahari
Copperbelt units known to hold copper-silver mineralisation, as well as to
confirm the efficacy of the exploration approach to identify the target
structures
· PL082 (on strike to Cobre Limited’s Ngami project): interpretation of
results indicates that underlying KCB geology can be observed through the Karoo
volcanic sequences, as well as clear areas of more conductive and more resistive
units, being possible indications of the target Ngwako pan and D’Kar formation
contact; these zones will be the focus of future exploration efforts
· PL231: identification of an interpreted anticlinal structure where the
Company will focus future exploration efforts, plus an indication of the
variation in depth of sand cover to bedrock across the licence area, which will
greatly assist decision making for the Company in using soil geochemistry as an
exploration tool
CEO, Robin Birchall, commented:
“I am very pleased with the speed at which our team has completed these first
geophysical programmes in the KCB, in accordance with the work requirements of
our licences, and analysed the results. This limited amount of work has provided
the Company with valuable information about the exploration methodology required
for exploration success in the KCB, and possible targets on these two licence
areas. The Company will utilise the funds raised as part of the recent listing
on AIM to move forward with the exploration programmes in order to generate
drill ready targets in due course.”
About the Geophysical Surveys
The surveys consisted of two blocks in PL082 and PL231 respectively. Each area
was surveyed with ground-based magnetics, time domain electromagnetic (“TDEM”)
and Audio-Magnetotellurics (“AMT”). Ground magnetics and TDEM were completed
along a total of 67.5 line-kilometres and a total of 299 stations for AMT.
The aim of the programmes is to:
1) provide insight into the thickness of the sand cover overlying the
target KCB units known as the D’Kar, Ngwako Pan, and potentially Mamuno
Formation;
2) serve as an orientation type survey, to establish which geophysical
method, or combination of methods, is best suited for identifying target
horizons and/or structures that could host mineralisation; and
3) assess the accuracy and improved results versus regional data for
eventual drill hole targeting.

PL082
PL082 is a priority target for Serval as it is directly adjacent and on strike
to Cobre Limited’s Ngami Project, which is a significant and growing copper
-silver deposit that has been delineated using a combination of geophysical
techniques and fieldwork, followed by extensive drilling. This is the
exploration model that the Company aims to follow at its KCB licences.
Existing regional data from the Botswana Geoscience Institute had indicated that
exploration for this area would be complicated due to the presence of Karoo
volcanic sequences, as well as traditional sand cover. Based on Serval’s
interpretation of structures using the ground magnetic data, the TDEM data as
well as the AMT apparent resistivity data, results indicate that the underlying
KCB geology can be observed through the Karoo volcanic sequences. AMT phase
tensor data also confirms the trends of structure identified from the magnetic
and TDEM data. The overburden and the cover sequences in this area are, as
expected, much more resistive and therefore depth to bedrock analysis is
inaccurate at present.
TDEM data indicates clear areas of more conductive and more resistive units,
known in the KCB as possible indications of the target Ngwako pan and D’Kar
formation contact. These zones will be the focus of future exploration efforts
for the Company in these licences.

PL231
PL231 is located to the west of the licence package, on the border with Namibia.
An important interpretation from the AMT data, is an anticlinal structure in the
northern part of the licence. Anticlinal structures that interact with the
target horizon are known structural traps for mineralisation in the KCB and this
feature will be the focus for follow up exploration in this area.
The survey also provided the Company with valuable information about the
efficacy of the exploration approach in the KCB. Total Magnetic Intensity,
Reduced to Pole, ground magnetic data indicated that features previously
identified from the regional airborne magnetic data are defined in much more
detail, as well as being shifted by about 100 metres towards the south. The
ground magnetic result thereby confirms to the Company that more extensive
ground based magnetic field work will more accurately define the underlying KCB
geology.
Furthermore, depth to bedrock (thickness of Kalahari sand cover) was interpreted
using a combination of TDEM and AMT inversion models and is interpreted to be
increasing in depth from about 20 metres in the north to about 90 metres in the
south of the licence area. Magnetic lineaments and structures were inferred from
the ground based magnetic data. Conductive elements were inferred from the TDEM
data and apparent resistivity from the AMT. Generally, the three datasets
complement each other well.
