Alpha Exploration Ltd. (TSXV: ALEX) has obtained positive results from recent drilling campaign at its Aburna gold prospect which consisted of 25 drill holes totalling 3,196 m.
Aburna is located in the southwest part of Alpha’s large (771 sq. km², 100% owned, Kerkasha Project in Eritrea.
“We are again, very encouraged about these latest drilling results from Aburna,” Michael Hopley, Alpha President and CEO, said.
“Given that the Aburna prospect is a huge area – over six km long and two km wide – as defined by Alpha surface sampling and mapping – and the fact that we have only drilled 43 holes to date – just over 5, 000 m in an area measuring about 2.5 km by 1.5 km and many holes have found strong gold mineralization over significant widths including two holes (ABR-037 and ABD-001) which intersected extraordinary results of 16m averaging 14.07 g/t and 20m averaging 7.70 g/t gold.
“The results to date suggest to me a major gold discovery by Alpha at Aburna; obviously more drilling is justified.”
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 six km x two km) 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 1.0-m long sub-surface channel and trench sampling. Results from all the above work identified five prospective sub-areas that warranted drill testing namely: Hill 52, Northeast, Celebration Hill, Aburna Central and Saddle Workings.
Anagulu gold-copper porphyry prospect
In July 2022, Alpha tested a deep (~200-500 m) chargeability anomaly in the southwest of the Anagulu prospect with one diamond tail hole (311.2 m) off existing RC hole ANR045 (240 m). This strong chargeability anomaly is coincident with elevated copper, gold, and molybdenum in previous drillholes in this area and was interpreted to be a potential source of the copper and gold mineralisation identified at surface over a two-km strike length in soil and rock-chip samples, trenching and drillholes. The drillhole was completed last month to the target depth of 551.2m.
Assay results for gold, copper and molybdenum have now been received from the “diamond tail” of ABRD045 and show broad zones of low-level copper mineralisation and elevated molybdenum near the end of the hole
At ~300 m, the potassic alteration encountered higher up the hole was replaced with phyllic alteration hosted in a quartz diorite that appeared to be largely unmineralized. At ~500 m the potassic alteration returned and persisted to the end of the hole. The potassic alteration near the end of the hole and increasing molybdenum content may indicate a return of mineralisation at greater depths.
Alpha believes that this drill hole has not, as hoped, found the source of the broad zones of copper and gold mineralization identified over a two km strike length at Anagulu at surface and in previous drilling. Further detailed analysis of the core from ANRD045, and surrounding area is warranted, to plan further work at Anagulu.
