Alpha Exploration Announces More Positive Drilling Results from Aburna






Alpha Exploration Ltd. (TSX-V: ALEX) announces initial drilling results from a 10,000m drill program underway on its Aburna Gold Prospect on the Company’s 100% owned, 771 km² Kerkasha Project located in Eritrea. Drilling consists of both reverse-circulation drilling and diamond drilling


Initial assays, including 20m @ 2.82 g/t Au (Hole ABR100) and 22m @ 1.71 g/t Au (Hole ABR105), have been received from ongoing drilling at Aburna where assays from nine drill holes from Central Area and three drill holes from Northeast Area have been completed to date. Significantly, these results have now established wide, continuous mineralization close to surface at Central Area for over 300m in strike, confirming a dominant northeast plunge that is open along strike and up and down plunge (Figure 1). At Northeast Area, assays received from three incomplete holes that have not yet drilled deep enough to hit their intended target and are testing a similar plunge orientation, have already intersected up to 2m @ 13.11 g/t Au (hole ABR108) and 1m @ 14 g/t Au (ABR109).


Aburna is a major, district scale orogenic gold prospect covering an area of at least 7km long and 2km wide and is one of the three significant discoveries made by Alpha on the Kerkasha licence in the last three years. Exploration to date by Alpha on the project has defined six primary areas of interest, and has established significant high-grade gold mineralised systems at Central Area, Hill 52 and Northeast Area (see Figure 2, below).



  • 20m @ 2.82 g/t Au, 22m @ 1.71 g/t Au and 24m @ 1.17 g/t Au reported from Central Area
  • 2m @ 13.11 g/t Au and 1m @ 14 g/t Au from partially completed holes from Northeast Area
  • Drilling defines significant shallow gold mineralised lens 300m long, fully open at Central Area
  • Plunging geometry of gold mineralization shoots at Central Area confirmed
  • Further drilling underway at Central, Hill 52 & Northeast area prioritising similarly oriented gold shoots


Drill Program


The Company commenced the current drill program in December 2023. To date, 33 holes for 5,188 metres have been drilled at Central Area (13 holes), Hill 52 (11 holes) and Northeast Area (9 holes). Assay results have been received from 14 of these 33 holes. A full table of significant intercepts from assay results received to date is available in Table 1, below.


Michael Hopley, Alpha President & CEO said, “We are very pleased with these early drilling results for two main reasons; firstly, our interpretation that mineralization is likely plunging to the northeast as “shoots” has been confirmed in Central Area. Secondly, these results have begun to define wide, consistent zones of near surface gold mineralization at Aburna that relate to higher-grade mineralization seen in prior drilling. These initial, positive assay results mark a major milestone in the understanding of the geometry of the mineralization at Aburna. A similar model of mineralization is being tested at both the Hill 52 and Northeast Areas and has the potential to significantly increase the size and scale of mineralized lenses so far defined on the project.


We are also very pleased to report that initial drilling at Northeast Area is already intersecting high grade gold mineralization including 2m @ 13.11 g/t Au from holes that have yet to be drilled deep enough to hit their intended target and will be completed with deeper DD ‘tails’ shortly. We look further to reporting further drill assay results when received.”

Dominant gold mineralization control confirmed at Aburna


Drilling completed at Aburna last year, ( established the potential that a dominant mineralization control at several prospects within Aburna including Northeast, Central and Hill 52 areas is likely plunging to the northeast, and contained within “shoots” orientated at 065-070°. The current, 10,000m drill program is designed to test this likely mineralization plunge at all three of these prospects amongst other drill targets. Visual mineralization estimations from RC chips and DD core at Central Area suggest that these plunging shoots are present and have been targeted effectively both up and down plunge. Further confirmation has now been received from the initial assays from Central Area with consistent, wide gold mineralization extended to over 300m following the plunge orientation.


Ongoing drilling at Central Area is testing the mineralized extension down plunge as well as confirming similar mineralization control at both the Hill 52 and Northeast Area targets.


Sampling, Sub-sampling and Analysis


Alpha engaged an independent Consultancy, RSC Mining & Mineral Exploration (RSC) to develop a Standard Operating Procedure for both RC and DD drill samples in June 2021 and all samples in this release use this RSC SOP. The RSC SOP utilizes blank standards and industry standards that are inserted at the beginning and end of every batch (and every 20 samples within the batch) for all batches submitted to ALS for assay. Additionally, field replicates are taken at a frequency of about 1 in 5 (20%) through mineralized areas.


One meter samples from both RC and DD drilling were crushed (to >90% passing 2.0 mm) and pulverised (to >85% passing 75 μm). Two scoop samples were taken from the pulveriser bowl: approximately 130g for laboratory analysis and approximately 150g for portable X-ray fluorescence (pXRF) analysis. The coarse and pulp rejects were stored at Alpha’s warehouse in Asmara. The Company inserted certified reference material from OREAS ( into the sample stream, while Nabro sample preparation facility inserted barren granodiorite material into the sample stream as a blank. 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 17025:2005 or certified to ISO 9001:2015 standards.


About Alpha


Alpha is an exploration company that is rapidly advancing a number of important gold and base metal discoveries across its 100% owned, large (771 km2) Kerkasha Project in Eritrea.


The Aburna Gold Prospect is an exciting new gold discovery where recent drilling has established a high-grade discovery with grades including 16 m @ 14.07 g/t Au, 9 m @ 10 g/t Au and 23 m @ 6.74 g/t Au. The Anagulu Gold-Copper Prospect includes recent drilling intersections of 108 m @ 1.24 g/t Au and 0.60% Cu and 49 m @ 2.42 g/t Au and 1.10% Cu within a porphyry unit mapped over at a >2 km strike length. The Company has also advanced the Tolegimja volcanogenic massive sulphide copper-zinc-gold Prospect and over 17 other gold prospects since listing in 2021.


The Company is managed by a group of highly experienced and successful professionals with long track records of establishing, building and successfully exiting a number of world class gold and base metals discoveries in Eritrea and across the wider Arabian Nubian Shield.
