Alpha Exploration (ALEX.V): Announces Results from Maiden Drilling at Tolegimja Copper-Zinc-Gold VMS Discovery
Calgary, Alberta–(Newsfile Corp. – June 6, 2022) – Alpha Exploration Ltd. (TSXV: ALEX) (“Alpha” or the “Company“) is pleased to announce assay results from the first drill program at its Tolegimja volcanogenic-massive-sulphide (‘VMS”) discovery. Tolegimja is one of seventeen prospects on Alpha’s 100% owned Kerkasha Project in Eritrea. The drill program of this prospect comprised nine reverse-circulation (RC) drill holes for a total of 1,862m and was completed in February this year. All assay results have now been received.
- Drill hole TLR-009 intersected 26 meters of massive and semi massive sulphide mineralization averaging 0.11 g/t gold, 0.38% copper and 1.67% zinc.
- Drill hole TLR-003 intersected 18 meters of massive and semi massive sulphide mineralization averaging 0.16 g/t gold, 0.34% copper and 0.99% zinc.
Table 1: Summary of Best Intervals from Tolegimja Drill Holes TLR-001 to TLR-009
Note: At this early stage of exploration the true width of the mineralization is uncertain, but it is estimated to be 70 to 80% of reported intervals. Averages for intervals are calculated with a start value of equal or greater than 1,000 ppm Cu or equal or greater than 3,000 ppm zinc, all gold values included in interval regardless of value. A minimum thickness for an interval is equal to or greater than 2m with maximum internal dilution of equal to or less than 2m.
Michael Hopley, Alpha President & CEO said, “To intersect massive-and semi-massive sulphide mineralisation up to 26 meters wide in 2 separate drill holes in the first 9 drill holes at the Tolegimja Prospect is very encouraging. Now that we have confirmed the presence of VMS-style mineralization obviously, more drilling is warranted over this 2.7 km long prospect in the near future.”
Tolegimja VMS Prospect
The Tolegimja prospect is a virgin discovery by Alpha geologists in the northeast of the Kerkasha Project approximately 50km south-southeast of the highly successful Bisha VMS copper-zinc-gold mine and was made during an initial property-wide soil geochemical survey. Prospect scale rock-chip, soil sampling and detailed geological mapping indicate the prospect is a bimodal-mafic copper-zinc-gold VMS occurrence with high copper values at the surface located over the contact between felsic and mafic rocks.
A limited initial drill program of 9 reverse-circulation drill holes (TLR001 to TLR009) was completed at Tolegimja in February this year for a total of 1,862 meters- see Map 1. Massive and semi-massive sulphide mineralization was intersected in holes TLR-003 and TLR009.
An Induced Polarization (IP)-Resistivity geophysical survey completed in Q3 2021, identified a strong chargeability anomaly over a 2km strike length immediately beside and beneath anomalous copper-zinc values at surface and directly beneath a mapped rhyolite unit. Rhyolite is considered a prime host for bimodal-mafic copper-zinc-gold VMS mineralization in the Arabian-Nubian shield. The drill campaign only tested a small part of the chargeability anomaly, the surface copper and zinc values and the rhyolite with 2 shallow RC drill holes (TRL-001 and TRL-002) – see Map 1. These holes were only drilled to a maximum of about 125 m beneath the surface, not deep enough to fully test the chargeability anomaly that commences at around 55m depth and continues to well below 300m, the depth extent of the survey. A more complete drill campaign to depth over this 2km trend is warranted.
The drill holes TLR003 and TLR009 that intersected massive and semi massive mineralisation, were drilled 500m and 650m to the northeast of the 2km long chargeability/rhyolite/surface copper-zinc anomalies mentioned above and designed to test a gossanous outcrop extending over 100m x 100m with an associated chargeability anomaly. This indicates there could be VMS mineralisation along this whole 2.7km trend.
Further drilling at Tolegimja is planned soon.

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 was by reverse circulation. Samples were split at the rig using a Metzke splitter, before being 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 analyzed all drill samples for gold by method Au-AA26 (50 g charge fire assay, AAS finish) and a multi-element suite by method ME-MS61 (Multi-element Ultra Trace method combining a four-acid digestion with ICP-MS instrumentation).
ALS is independent of the Company and its quality management systems framework is accredited to ISO/IEC 17025:2005 or certified to ISO 9001:2015 standards.

Alpha is an exploration company listed on the TSX-V exchange under the symbol ALEX that has made 3 important discoveries in the past 2 years at it’s 100% owned Kerkasha Project in Eritrea:
- Porphyry Copper-Gold: Anagulu Prospect
- Volcanogenic-Massive-Sulphide (VMS): Tolegimja Prospect.
- Orogenic Gold: Aburna Prospect
The company is managed by a group of highly experienced and successful professionals with many years of experience carrying out exploration and resource development programs in Eritrea and Sudan and is focused on the discovery of world class economic gold and base metals deposits in the highly prospective Arabian-Nubian shield, on either side of the Red Sea. Alpha currently holds a 100% interest in the large (771 km2) Kerkasha Exploration License in southwest Eritrea, located 135 km west-southwest of the capital city of Asmara. Since acquiring the property in January 2018, the company has spent approximately CAD$13 million on exploration and identified 17 prospects of which six have been drilled to date.
