Calgary, Alberta--(Newsfile Corp. - November 24, 2022) -
Alpha Exploration Ltd.
(TSXV: ALEX)
("
Alpha
" or the "
Company
") is pleased to announce results from recent drilling campaign at its Aburna
gold prospect which consisted of 25 drill holes totalling 3,196 m. Aburna is located in the southwest part

Note
: At this early stage of exploration, the true width of the mineralization is uncertain, but it is estimated to be 80% of reported intervals. Intervals
were calculated with a start and finish value of no less than 0.5 g/t gold, a minimum width of 2 m and maximum internal dilution of 2 m at >0.2g/t gold.
Michael Hopley, Alpha President & CEO said "We are again, very encouraged about these
latest drilling results from Aburna. Given that the Aburna prospect is a huge area - over 6 km
long and 2 km wide - as defined by Alpha surface sampling and mapping - and the fact that
we
have only drilled 43 holes to date - just over 5, 000 m
in an area measuring about 2.5 km by 1.5
km and many holes have found strong gold mineralization over significant widths including
two holes (ABR-037 and ABD-001) which intersected
extraordinary results
of 16m averaging
14.07 g/t and 20m averaging 7.70 g/t gold. The results to date suggest to me
a major gold
discovery by Alpha at Aburna; obviously
more drilling is justified."
Aburna Gold Prospect
The Aburna gold prospect is located on the western side of the Company's Kerkasha Exploration
License. Gold was mined at Aburna in the 1920s by Italian colonial miners and more recently by local
artisanal miners. Earlier soil and rock-chip sampling by Alpha identified gold mineralization over a large
area (approximately 6 km x 2 km) northeast of the colonial mine. Gold mineralization at Aburna is
orogenic-type associated with three major NE-SW oriented shear zones. Recent work by Alpha has
included continuous 1-m long sub-surface channel and trench sampling (See press releases on 4
th
November 2021 and 10
th
February 2022). Results from all the above work identified five prospective
sub-areas that warranted drill testing namely: Hill 52, Northeast, Celebration Hill, Aburna Central and
Saddle Workings.

* First reported on September 14, 2022
Note: ABR designated drill holes were drilled using the reverse-circulation method and ABD designated drill holes were drilled using the diamond-
drilling method. Intervals were calculated with a minimum start and finish value of 0.5 g/t gold, a minimum width of 2m and maximum internal dilution of
2 m at >0.2g/t gold. Any single meter interval >1g/t gold is also reported.
Anagulu gold-copper porphyry prospect
As announced on July 7, 2022, Alpha tested a deep (~200-500 m) chargeability anomaly in the
southwest of the Anagulu prospect with one diamond tail hole (311.2 m) off existing RC hole ANR045
(240 m). This strong chargeability anomaly is coincident with elevated copper, gold, and molybdenum in
previous drillholes in this area and was interpreted to be a potential source of the copper and gold
mineralisation identified at surface over a 2-km strike length in soil and rock-chip samples, trenching and
drillholes. The drillhole was completed last month to the target depth of 551.2m.
Assay results for gold, copper and molybdenum have now been received from the "diamond tail" of
ABRD045 and show broad zones of low-level copper mineralisation and elevated molybdenum near the
end of the hole as follows:

Note: No cut-off parameters were used in the interval calculations for gold, copper and molybdenum
in table 2 above.
The assay grade given is the
sum of the individual meter assays, divided by the interval length.
At ~300 m, the potassic alteration encountered higher up the hole was replaced with phyllic alteration
hosted in a quartz diorite that appeared to be largely unmineralized. At ~500 m the potassic alteration
returned and persisted to the end of the hole.
The potassic alteration near the end of the hole and
increasing molybdenum content may indicate a return of mineralisation at greater depths.
Alpha believes that this drill hole has not, as hoped, found the source of the broad zones of copper and
gold mineralization identified over a 2 km strike length at Anagulu at surface and in previous drilling.
Further detailed analysis of the core from ANRD045, and surrounding area is warranted, to plan further
work at Anagulu.
Sampling, Sub-sampling and Analysis
Geological consultants from RSC were responsible for the design of a strict QA/QC program consistent
with industry best practice. Drilling of the reported intervals was by both reverse-circulation (RC) and
diamond drilling. RC samples were split at the rig using a Metzke splitter, before being transported to a
secure location for logging. Diamond drill core was cut in half longitudinally at site using a diamond saw
and half of the core (in 1-meter intervals) was transported to a secure location for logging.
All samples were submitted to Nabro Laboratories Limited (Nabro), Asmara, Eritrea, for sample
preparation. Samples were crushed (to 90% passing 2.8 mm) and pulverised (to 85% passing 75 µm).
Two scoop samples were taken from the pulveriser bowl: approximately 120 g for laboratory analysis
and approximately 100 g for portable X-ray fluorescence (pXRF) analysis. The coarse and pulp rejects
were stored at a warehouse in Asmara. The Company inserted certified reference material from OREAS
(www.ore.com.au) into the sample stream, while Nabro inserted barren granodiorite material into the
sample stream as a blank. Drill samples were shipped to ALS Geochemistry (ALS), Loughrea, Ireland,
for analysis. ALS analysed all drill samples for gold by method Au-AA26 (50 g charge fire assay, AAS
finish). ALS is independent of the Company and its quality management systems framework is
accredited to ISO/IEC 17025:2005or certified to ISO 9001:2015standards.
