Alpha Exploration Reports Aburna Gold Latest Drill & Channel Sampling Results

 

 

 

 

 

13M @ 4.24 G/T AU
11M @ 3.99 G/T AU
6M @ 4.97 G/T AU

 

Alpha Exploration Ltd. (TSX-V: ALEX)  is pleased to announce results from recent drilling in 2023 at its Aburna Gold Prospect, which consisted of ten Reverse Circulation drill holes totalling 1,188m, from the Northeast Target Area. We have also received assay results from a single RC hole (ABR068 to 100m) in the Dasharna Target Area but, this had no significant results. We are also announcing assay results from 10 channels sampled at Aburna in 2023. Aburna is located in the southwest part of Alpha’s large (771 km²), 100% owned, Kerkasha Project. Drilling is ongoing and further information will be released when available and interpreted.

Northeast Area ABR042 111 112 1  3.58

 

Note:

  • At this early stage of exploration, the true width of the mineralisation is uncertain, but it is estimated to be 80% of reported intervals. Intervals were calculated with a start and finish value of no less than 0.2 g/t gold, a minimum width of 2m and maximum internal dilution of 2m at >0.2g/t gold.

 

Michael Hopley, Alpha President & CEO said, “The significant drill results returned from the Northeast Target Area (see Table 1 and Figure 1) within the Aburna Prospect have extended the mineralisation in drilling along strike from 90m to 185m. The mineralisation remains open along strike in both directions and down dip. The Northeast Area is ¬1.3kms north-northeast of the Central Area, where Alpha has also retuned significant drill results (see press release on 22 May 2023). Alpha will need to drill test the area between Central and Northeast to see if they merge. Significant potential also exists northeast of the current drilling at the Northeast Target Area, as demonstrated by the 2.5km long soil anomalies in this area (see Figures 3 & 4). Further drilling is warranted in the Northeast Target Area.”

Michael Hopley, Alpha President & CEO said, “The significant result returned from channel sampling in the Saddle Workings Target Area (6m @ 5.26 g/t gold) warrants follow up drilling. The Alpha process of soil sampling followed up with traverses of trench and channel sampling (1m intervals) is proving to be an effective method to locate drill holes that can intersect significant mineralisation.”

The gold anomalies from soil, channel and trench sampling that define the Northeast and Dasharna Target Areas cover a strike length of approximately 2.5kms. This 2.5km anomalous area is part of a much larger 7.2km long gold anomalous zone from soil, channel and trench sampling that has seven Target Areas in total (Aburna Colonial Gold Mine, Saddle Workings, Celebration Hill, Hill 52, Central, Northeast and Dasharna) that define the Aburna Prospect as a whole (see Figures 3 & 4).

Michael Hopley, Alpha President & CEO said, “The Aburna Prospect is continuing to demonstrate it has the potential to return a multi-million ounce gold deposit. The Hill 52, Central, Northeast and Celebration Hill Target Areas drill tested to date (see Fig 5) , have all returned widths and grades (see Table 4) that could conform to an economic deposit.”

 

To date, Alpha has completed a total of 5 Diamond drill holes for 881.1m and 76 Reverse Circulation drill holes for a total of 9,209m at Aburna.

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. Soil and rock-chip sampling by Alpha identified gold mineralisation over a large area (¬7.2 km x 2.2 km) northeast of the Colonial Mine. Gold mineralisation at Aburna is orogenic type associated with a major (¬2km wide) SW-NE oriented shear zone. Work by Alpha has included regional rock chip sampling, 100m x 100m soil sampling, lithological and structural mapping, with 1m traverse-channel-trench sampling. Results from all the above work identified seven prospective sub-areas that warranted drill testing namely: Aburna Mine, Saddle Workings, Celebration Hill, Hill 52, Central, Northeast and Dasharna. Drilling has returned significant intercepts for gold from the Hill 52, Northeast, Celebration Hill and Central Areas. No significant results were returned from 2 drill holes at Saddle Workings and 1 drill hole at Dasharna. The Aburna Colonial Mine is yet to be drill tested. Petrographic studies are underway along with a ground magnetic survey. An induced polarisation survey is due to commence in late May 2023 and preliminary metallurgical test work is expected to commence on drill samples in Q3 2023.

 

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 both reverse-circulation and diamond drilling. RC samples were split at the rig using a Metzke splitter, before being transported to a secure location for logging. Diamond drill 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 a blank. Drill 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 17025:2005or certified to ISO 9001:2015standards.

 

About Alpha

 

Alpha is an exploration company listed on the TSX-V exchange under the symbol ALEX that has made three important discoveries in two years at it’s Kerkasha Project in Eritrea:

  • Aburna orogenic gold
  • Anagulu porphyry gold-copper
  • Tolegimja volcanogenic-massive-sulphide (VMS)

 

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 ~CAD$16 million on exploration and identified 20 prospects of which six have been drilled to date.
