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 20th 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 25th 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.
