Alpha Exploration Completes Diamond Drilling at Kerkasha Project and Announces First Results
Drill Hole at Aburna Gold Returns 20m at 7.73 g/t Gold
Calgary, Alberta--(Newsfile Corp. - September 14, 2022) - Alpha Exploration Ltd. (TSXV: ALEX) ("Alpha" or the "Company") is pleased to announce that it has recently completed the diamond drilling part of the drilling program that was announced on July 7th 2022, and consisted of approximately 1,000 meters of diamond drilling and 3,000 meters of reverse-circulation drilling on three of its most important prospects on its large 100% owned Kerkasha Project, Eritrea. In addition, assay results have been received from the first diamond drill hole (ABD-001) on its Aburna gold prospect.
Highlights from ABD-001
- Drill hole ABD-001 in the Hill 52 area of Aburna intersected the following best intervals:
- From 17 to 33 meters, 16 meters averaging 0.46 g/t gold
- From 45 to 59 meters, 14 meters averaging 1.09 g/t gold
- From 66 to 72 meters, 6 meters averaging 6.11 g/t gold
- From 89 to 109 meters, 20 meters averaging 7.73 g/t gold
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. Intervals were calculated with a start and finish value of 0.5 g/t gold and a minimum width of 2m and maximum internal dilution of 2 m at >0.2g/t gold.
Michael Hopley, Alpha President & CEO said, "The diamond drilling program on the four prospects on the Kerkasha project is intended to increase understanding of the geology and structural controls of mineralization. At Aburna the assay results from this first diamond drill hole verify the strong gold mineralization previously discovered in this area. The core from this hole is being studied in detail and will be of great help in the planning of future drill programs in the Hill 52 area."
On July 7th 2022, Alpha announced the start of a drill program consisting of approximately 1,000 meters of diamond drilling and 3,000 meters of reverse-circulation (RC) drilling at three of its prime prospects on its large Kerkasha Project in Eritrea. These prospects are the Aburna orogenic gold prospect, Tolegimja copper-zinc-gold volcanogenic-massive-sulphide (VMS) prospect and the Anagulu gold-copper porphyry prospect. An additional target area known as Kona West, a copper VMS prospect, was added to the drilling program. The overall drilling program is now largely complete with assay results received to date from the single diamond drill holes at Aburna, Tolegimja and Kona West. Assay results for the balance of the drilling are expected by late October to early November.
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 5 x 2 kms) 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 4th November 2021 and 10th February 2022). Results from all the above work has defined six prospective sub-areas namely: Hill 52, Saddle Workings, Channel 12 Northeast, Celebration Hill, Pad 2 and Aburna Central.
ABD-001 is the first diamond drill hole at Aburna. A further twenty RC holes were planned for this area in this current program, fifteen have been completed to date and the remainder should be completed in one week with assay results expected in late October-early November 2022.

Tolegimja copper-zinc-gold VMS prospect
As part of the current drill program, Alpha completed one diamond drill hole (TLD-001) to test the large Induced Polarization (chargeability) anomaly located approximately 600m to the southwest of previous RC drill holes TLR-003 and TLR-009, where significant widths of copper and zinc mineralization were intercepted (see Alpha news release dated June 6, 2022). TLD-001 was drilled to 400 meters depth revealing mostly diorite with very little evidence of VMS-style mineralization; assay results have been returned for this hole and there were no significant results. A further two RC holes are planned at Tolegimja as part of the current drill program.
Kona West copper VMS prospect
As part of the current drilling program, one vertical diamond drill hole (KNRD-011) was completed as a 'tail' off an existing RC hole (KNR-011) to test a 200m deep, sub horizontal chargeability anomaly immediately southeast of significant copper mineralisation in gossans at surface. Assays results have been returned for KNRD-011 and there are no significant results.
Anagulu gold-copper porphyry prospect
As announced on the 7th of July 2022, Alpha is testing a deep (~200 - 500 m) chargeability anomaly in the southwest of the Anagulu prospect with one diamond hole (as a tail off existing RC hole ANR-045). This very strong chargeability anomaly is coincident with elevated copper, gold and molybdenum in previous RC drill holes in this area and is interpreted to possibly be the source of the copper and gold mineralisation identified at surface over a 2km strike length in soils, rock chip sampling, trenching and limited drilling. The hole has been completed to the target depth of approximately 550m. Assays are expected in October 2022.
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 diamond drilling. 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 blanks.
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). 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.
