Key Points
- Drilling Highlights: Alpha Exploration Ltd. reports further drilling results from its ongoing 10,000-meter drill program at the Aburna gold prospect on the Kerkasha project in Eritrea. Significant intercepts include 18m @ 15.33 g/t Au and 49m @ 2.75 g/t Au (including 7m @ 14.90g/t Au).
- Extension of High-Grade Zone: The drilling has extended a wide, high-grade zone of mineralization to over 200 meters at Hill 52, confirming shallow plunging geometry of gold mineralization at both Central Area and Hill 52.
- Project Overview: Aburna is a major orogenic gold prospect covering an area of at least 7km long and 2km wide, one of three significant discoveries made by Alpha on the Kerkasha license in the past three years. The company has established significant high-grade gold mineralized systems at Central Area, Hill 52, and Northeast Area.
Alpha Exploration Ltd. has released further drilling results from a 10,000-metre drill program under way on its Aburna gold prospect on the company’s 100-per-cent-owned, 771-square-kilometre Kerkasha project located in Eritrea. Drilling consists of both reverse circulation (RC) drilling and diamond core (DC) drilling.
Highlights:
- 18m @ 15.33 g/t Au from RC-DC hole ABD012 (Hill 52);
- 49m @ 2.75 g/t Au (including 7m @ 14.90g/t Au) from RC-DC hole ABD013 (Hill 52);
- Highest grade mineralization intersected to data across the Aburna project;
- Drilling extends wide, high-grade zone to over 200 metres at Hill 52;
- Shallow plunging geometry of gold mineralization now confirmed at Central Area and Hill 52.
Assays have been received from a further 16 holes completed over the Hill 52, Central and Northeast Area prospects on Aburna. Hole ABD012 intersected 15.33 g/t Au over 18m and was drilled as a step out along strike from existing high- grade mineralization that included holes ABD001 (20m@ 7.70 g/t Au). ABD013, a step out from ABD012, intersected 49m @ 2.75 g/t Au a nd included two separate higher-grade zones of 7m @ 14.90 g/t Au and 2m @ 6.19 g/t Au at shallow depths (<70m from surface).
In combination, holes ABD012 and ABD013 have significantly extended a wide, high-grade zone of mineralization that was originally defined in 2022 by the Company and reported in drill holes ABR005 (15m @ 5.85 g/t Au), ABR018 (8m @ 5.47 g/t Au) and ABD001 (20m @ 7.70 g/t Au).
Additional new results include hole ABR114 (6m @ 4.5 g/t Au and 2m @ 11.91 g/t Au ), that has further defined a separate mineralized structure within Hill 52.
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 mineralized systems at Central Area, Hill 52 and Northeast Area.
Michael Hopley, Alpha President & CEO said, “We are very pleased to report these spectacular results from the ongoing drill program at Aburna. In particular, holes ABD012 and ABD013 have exceeded all of our expectations by extending to over 200m a high-grade shoot originally identified in 2022. ABD012 (15.33 g/t Au over 18 metres) and translating to >275 gram metres is the highest grade result we have reported on the Aburna project.
“The identification of shallow, plunging high-grade mineralization at Hill 52 following similar confirmation at Central Area last month, is testament to the strength of our technical team and the work completed to date. The team is already preparing additional drill targets to extend this zone further which remains open down dip and down plunge, with drilling expected to restart in the next few weeks.
“We look forward to reporting further assay results on the project as data is released as well as the imminent start of the second phase of the 10,000 metre drill program at Aburna.”
Drill Program
A further 19 drillholes have been completed at Aburna and these have principally been completed at the Hill 52 prospect (11 holes), 3 drillholes at the Central Area with a further 5 drillholes at Northeast Area. Of the 11 holes completed at Hill 52, five (ABD116,-118,-120,-121 and -122) are partially reported and are awaiting assays from the diamond core ‘tail’ of drillholes which are expected shortly.
The Company commenced the current drill program in December 2023. To date, 33 drillholes for 6,033 metres have been drilled at Central Area (13 drillholes), Hill 52 (11 drillholes) and Northeast Area (9 drillholes). Further assay results have been received from 16 of these 33 drillholes.
Shallow plunging gold mineralization confirmed at Hill 52 and Central Areas, Aburna
Drilling completed at Aburna last year established the potential that shallow plunging mineralized “shoots” exist at several prospects within Aburna including Northeast, Central and Hill 52 areas. These mineralized “shoots “plunge at an azimuth of 065-070 degrees to the east-northeast.
Drilling in both Central and Hill 52 areas has now confirmed that mineralization at Aburna plunges as expected. At Central Area, consistent, wide, lower-grade gold mineralization extends over 300m in the down plunge orientation. At Hill 52 mineralization is less consistent but equally as wide containing multiple zones of high-grade mineralization extending over 200m in the down plunge orientation.
The highly mineralized shoot at Hill 52 as defined by AND001 and ANR008 (2022) and recent drillholes AND012 and AND013 (additional assays pending), is proving to be larger in size and higher in grade than expected. The shoot daylights at AND001 and 80m to the NE at AND013, mineralization is intersected 10m below the surface suggesting a very shallow plunge at an azimuth of 068degree. The shoot is wholly contained within a highly foliated portion of a larger shear zone. The higher-grade portions of the shoot are developed within dilate areas created by internal structures within the shear zone. The high-grade zones are generally contained within an envelope of lower-grade material that is often 50m to 60m wide (i.e., ABD012 with 49m @ 2.75 g/t Au). The Hill 52 shoot is fairly well defined for 200m along strike and is open down dip and down plunge. Its size and grade are a key focus for Alpha as we look to extend the primary mineralized shoots at all three sub-areas on the Aburna prospect.
A significant interval is defined by consecutive one-meter intervals starting and ending at 0.20 g/t Au or better. A significant interval must be at least 3m long. Internal dilution is limited to 2 consecutive intervals of <0.20 g/t Au. Multiple internal dilutions are allowed. Single one-meter intervals of 1.00 g/t Au or greater are also considered significant. At this early stage of exploration, the true widths of intersections is not known but is estimated to be at least 80% of the reported intervals.
Sampling, Sub-sampling and Analysis
Alpha engaged an independent Consultancy, RSC Mining & Mineral Exploration (RSC) to develop a Standard Operating Procedure (“SOP”) 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 (www.ore.com.au) 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.
Alpha Extends Closing Date of Private Placement Financing
Further to the Company’s press releases dated November 15, 2023, December 8, 2023, January 2, 2024 and February 7, 2024, Alpha is pleased to announce that the TSX Venture Exchange (the “Exchange” ) has agreed to extend the closing of the second tranche of its previously announced non-brokered private placement of units in the capital of the Corporation ( “Units” ) of up to $5,000,000.00 at a purchase price of $0.70 per Unit (the “Offering Price” ), (the “Offering” ) until March 31, 2024. The first tranche of the Offering closed after market close on December 7, 2023, for total aggregate gross proceeds of $4,180,001.00 as previously announced by the Corporation. The principal use of the proceeds of the Offering will be for funding ongoing exploration work on the Kerkasha Project in Eritrea, operating and administrative expenses, working capital and general corporate purposes.
Certain Insiders of the Corporation (as such term is defined under the policies of the TSXV) may participate in the Offering. The participation of Insiders in the Offering would constitute a “related party transaction” within the meaning of Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions ( “MI 61-101” ). The Corporation intends on relying upon exemptions from the formal valuation and minority approval requirements of MI 61-101 based on a determination that the fair market value of the Offering, insofar as it involves the related parties, will not exceed $2,500,000.
Further details relating to the closing of the second tranche of the Offering will be provided in due course.
