Alpha Expands the Footprint of the Anagulu
Copper-Gold Porphyry and New Camel Target
Zone Measures at Least 1 x 0.25km
Calgary, Alberta--(Newsfile Corp. - April 9, 2026) -
Alpha Exploration Ltd.
(TSXV: ALEX)
("Alpha" or
the "Company")
is pleased to announce recently received shallow Rotary Air Blast ("RAB"), core
drilling and expanded reconnaissance termite mound sampling program at the Anagulu Copper-Gold
Porphyry Project. To date results are available from 2,584 metres of an ongoing RAB drilling program
being conducted to define targets from initial termite mound sampling copper anomalies. Also, provided
are complete drilling results from a program of 1,585 metres of Reverse Circulation ("RC") and core
drilling completed from the end of 2025 and early 2026 exploration program.
This project is located within its 100% owned, 514km² Kerkasha Project located in Eritrea. The Anagulu
copper-gold porphyry was discovered by the Alpha team through surface sampling and mapping with
follow-up drilling. The project is located some 7 kilometres south of the Company's shallow, Aburna Gold
Project and these projects are two of three significant discoveries made by the Alpha team on the
Kerkasha licence.
HIGHLIGHTS OF RECENT ANAGULU PORPHYRY RAB, CORE & RC DRILLING AND TERMITE
MOUND SAMPLING RESULTS
Shallow RAB drilling delivers new Camel Target Zone ("Camel") of at least 1 kilometre
along trend and is open into a large area of recently sampled termite mounds anomalous
in copper
Camel RAB sample results range from 1,358 parts per million (ppm) to 389 ppm copper
Camel is separate but parallel to drilled copper-gold mineralization some 500 metres to
northwest
RAB drilling also identified copper target zones extending some 1 kilometre northeast
from drilled intercepts on section line SS-45
Core drilling results from ANRD041: 25.00 metres grading 0.55 percent copper ("%") and
0.16 grams per tonne ("g/t") gold.
Including:
14.00 metres grading 0.84% copper and 0.26
g/t gold
This intercept confirms the drilled extension of the mineralised porphyry unit, to the
northeast, as previously reported in ANRD049 interval of 120 metres grading 0.30%
copper and 0.47 g/t gold, on the same section line (SS-45)
The mineralised unit sub-crops on this section line
Based upon current data and interpretation it is estimated true widths range between 50% and 70% of the drilled intersections.
John Wilton, CEO of Alpha, stated:
"These recent results from the ongoing exploration field
activities at our Anagulu Copper-Gold Project further indicate the increased scale potential of this
porphyry system. The shallow RAB drilling, following up on results from initial reconnaissance termite
mound sampling, has delivered several new and compelling targets for RC and core drill testing.
The new Camel Target Zone appears especially exciting as it represents a new separate target of
scale, with robust copper values, trending parallel to the known Anagulu copper-gold mineralization.
The Camel Target Zone is currently mapped by the RAB copper results as at least 1 kilometre along
trend and some 250 metres in width. Importantly this target zone is open to the south and west
trending towards an extensive area of anomalous copper samples from termite mounds.
In addition,
the RAB program has provided target zones extending some 1 kilometre along the northeast trend of
the drilled higher-grade spine to the copper-gold mineralized porphyry units. These targets will be
RC/core drill tested in the Company's planned Q2-Q3 exploration program along with drilling our
Aburna Gold Project."
ANAGULU COPPER GOLD PROJECT: RAB DRILLING AND TERMITE MOUND SAMPLING
RESULTS
Alpha's ongoing RAB drilling program at the Anagulu Project has to date completed 316 holes for some
2,584 metres with an average depth of approximately 8.2 metres per hole. This shallow RAB drilling
program is deployed as a rapid and cost-effective reconnaissance exploration method as an initial test
and to define copper anomalies from termite mound sampling in areas of predominantly transported soil
cover. The RAB holes provide bedrock and weathered bedrock geological and geochemical
information.
Figure 1 illustrates the results to date from the ongoing RAB program with a number of robust copper
geochemical targets have been identified. Collectively the new copper zone targets delivered so far from
the RAB drilling represent a significant expansion to the exploration target footprint of the Anagulu
copper-gold porphyry mineralization (see Figure 1).
One of the most compelling new targets is the Camel Target Zone ("Camel") that represents an area of
at least 1 kilometre along its northeast to southwest trend and some 250 metres in width. The tenor of the
RAB samples within the Camel ranges from 1,350 ppm to 389 ppm copper. These results compare
favourably with surface and soil sampling copper results associated with the sub-crop of drilled copper-
gold mineralization previously discovered by the Alpha exploration team at the Anagulu Project.
Importantly this new target zone remains open to further expansion to the south and west into a large
area of copper anomalies recently returned from termite mound sampling (see Figure 1). The southwest
to northeast trend of the Camel copper anomaly runs parallel to the drilled and mineralized Anagulu
porphyry units some 500 metres to the northwest, and it is currently interpreted this could represent a
second mineralized units (see Figure 2). The value and application of the termite mound sampling
results is that they provide very efficient and cost-effective reconnaissance copper geochemical
sampling in areas of expected thin but transported soil cover. The termite burrowing activity brings
sample material up from depth to the surface reflecting bedrock anomalies.
In addition to the Camel, the RAB drilling has returned copper target zones extending for some 1
kilometres, along trend to the northeast, from section line SS-45. Figure 1 shows one of these target
zones with values frequently over 400 ppm copper with a range from 1,010 to 358 ppm copper and an
area of some 600 metres along trend and 200 metres width. Table 1 includes details of the selected
RAB sample results and Table 3 details RAB drillhole ID, azimuth, hole dip (vertical), end of hole depth
with collar coordinates.
ANAGULU COPPER GOLD PROJECT: CORE & RC DRILLING RESULTS
These new results reported here for drill holes ANDR041 and ANRD047 relate to a final batch of
laboratory data from a phase of drilling conducted in late 2025 and early 2026 comprising 597 metres of
Reverse Circulation ("RC") and 988 metres of diamond core ("DC") drilling.
Figure 1 indicates the location of drill hole ANDR041 with its sampling results on a map of the Anagulu
Project area. This intercept of 25.00 metres grading 0.55% copper and 0.16 g/t gold, including: 14.00
metres grading 0.84% copper and 0.26 g/t gold traces the previously reported drilled interval in
ANDR049 of 120 metres grading 0.30% copper and 0.47 g/t gold some 100 metres vertically towards
the surface (see Figure 2). Section line SS-45 now provides two drill hole intercepts confirming the
extension of the mineralized porphyry unit at least 120 metres to the northeast from the previous phases
of drilling. Figure 2 also shows drill holes from two adjacent lines SS-44 and SS-46 which have been
projected, 40 metres each, to provide geological context. The cross section demonstrates the quartz
diorite porphyry unit (
purple colour on drill hole traces
) is interpreted to be developed from surface to at
least a vertical depth of some 240 metres below the collar of ANRD049.
Drill hole ANRD047 is located some 1,750 metres to the southwest of ANDR041 as illustrated on Figure
1. This drill hole has returned an interval of 22 metres grading 0.37% copper and 0.10 g/t gold with an
included interval of 6 metres grading 0.96% copper and 0.24 g/t gold. Drilling at the original discovery
area of the Anagulu Project has returned a several meaningful copper-gold intercepts within the porphyry
units over at least 2 kilometres along its southwest to northeast trend. This widespread copper-gold
mineralization at Anagulu is hosted in a suite of fractionated intrusive units containing typical
disseminated and vein hosted porphyry copper-gold textures.
Table 2 includes details of the selected drill hole intervals and Table 4 details drillhole ID, azimuth, hole
dip, end of hole depth with collar coordinates.
POSITIVE IMPLICATIONS OF COMBINED RECENT CORE/RC/RAB DRILLING AND TERMITE
MOUND SAMPLING RESULTS AT ANAGULU COPPER GOLD PROJECT
The Anagulu porphyry system had already been drilled and recognised from copper in soil data to
extend for some 2 by 0.5 kilometres by the Alpha exploration team. This area includes drilled intercepts
such as ANR031 which returned 63 metres grading 0.57% copper and 0.94 g/t gold and AND001
intersecting 110 metres grading 0.57% copper and 1.24 g/t gold (previously reported see Figure 1).
The recent exploration data from RC/core and RAB drilling now delivers further compelling and robust
exploration targets within an overall increased scale Anagulu copper-gold porphyry target exploration
footprint of at least some 4 by 2 kilometres. Furthermore, recent anomalous copper results from termite
mound sampling clearly indicates and motivates new areas for future RAB drilling target definition ahead
of RC/core testing.

Table 1 Notes: Intertek completed the analytical work with analytical procedures conducted in an Intertek laboratory in Tarkwa, Ghana. Sample
preparation was undertaken by an independent laboratory NABRO in Asmara, Eritrea and the pulps shipped to Intertek, Ghana. Based upon
current data and interpretation it is estimated true widths range between 50% and 70% of the drilled intersections. A nominal cut-off grade of
0.10% Cu has been used to determine the boundaries of these intersections with no more than 6 metres of internal dilution of the intercepts.
QUALITY ASSURANCE AND QUALITY CONTROL
The results reported here for the Reverse Circulation ("RC") and Diamond Core ("DC") drilling were
analysed by Intertek Minerals Ltd., an independent and accredited laboratory located in Tarkwa, Ghana.
The RC and DC drilling was managed by Alpha Exploration's field team with the field operations
conducted in-line with the standard operating procedures implemented at this project. Alpha uses an
independent laboratory in Asmara (NABRO) to prepare drill samples for assaying. Representative one-
metre samples from the RC drilling and half core samples of the HQ & NQ size and quarter core for PQ
size, were crushed (to >90% passing 2.0 mm) and pulverised (to >85% passing 75 micron). A scoop
sample of approximately 60g for laboratory analysis was taken. The coarse and pulp rejects were stored
at Alpha's warehouse in Asmara. The Company uses appropriate duplicate samples and inserts
certified reference material from OREAS (www.ore.com.au) into the sample stream. NABRO sample
preparation facility inserts barren granodiorite material into the sample stream as blanks. The 60g sub-
samples with inserted QA/QC samples of blanks and certified reference material every 20
th
field sample
were shipped to Intertek Minerals, Tarkwa, Ghana. The gold results at the laboratory were determined by
using a 30g sub-sample for Fire Assay ("FA") and Atomic Absorption Spectroscopy ("AAS") finish
(Intertek Code: FA30/AA). The Multi element (including copper) results were determined using a 30g
sub-sample for Four acid 48 elements package ("4A") and low-level sulphur 50ppm ("OM48") with Mass
Spectrometry ("MS") finish (Intertek Code: 4A/OM48).
The RAB drilling was managed by Alpha Exploration's field team with the field operations conducted in-
line with the standard operating procedures implemented at this project. Representative material of
bedrock and weathered bedrock for the deepest two, one-metre, samples of each RAB drill hole, were
screened to provide approximately 200 grams ("g") of minus 75-micron material. Termite mound
samples are collected and processed in-line with the standard operating procedures implemented at
this project. Four sub-samples of each mound are sampled collecting approximately a 2kg sample. This
sample is gently pulverized to break up any soil clods and sieved to -75um to obtain a uniform
representative sample. For the RAB and termite mound samples an aliquot is collected using a scoop
and a sub-sample analysed with QA/QC samples inserted every 25
th
field sample by Portable X-ray
Fluorescence ("pXRF") within the Company's field laboratory in Asmara, Eritrea. The pXRF is routinely
monitored by the QA/QC sample results to check its calibration.
