Toronto, Ontario (FSCwire) - Alexander Nubia International Inc. (TSX-V: AAN) (the “Company”) is pleased to report diamond drill results in a previously untested area of Hamama East, part of the 3,000 metre-long Main Horizon, and 1,000 metres east of the Gold-Oxide Cap in Hamama West. All six diamond drill holes, spaced 75 to 160 metres apart, intersected zinc-copper mineralization, and five of the holes intersected additional gold and silver mineralization in the structural footwall of the Main Horizon.
Drill results suggest the Main Horizon at Hamama East contains multiple stacked zinc and copper-mineralized zones and is continuous over 450 meters strike length. Widths and grades increase with depth, with multiple zones merging into one zone of 46.5 metres true width grading 1.67% zinc and 0.11% copper in AHA-53. Pending are additional drill results for Hamama Central and Hamama West.
HIGHLIGHTS:
- Drilling at the Main Horizon of Hamama East intersected mineralization across 450 metres (m) strike length and down to 170 m vertical depth
- Base-metal-rich zones average 7 - 14 m in width; AHA-49 intersected 7.65 m grading 2.71% Zn, 0.30% Cu, 0.96% Pb and 12.5 g/t Ag
- In AHA-53, containing the deepest intersection in Hamama East, a mineralized zones 46.5 m wide, grades 1.67% Zn and 0.11% Cu, including zones richer in copper of 3.7 m at 0.33% Cu and 4.9 m at 0.18% Cu.
- Gold-and silver-mineralization occurs within the Main Horizon, connecting surface trench results and shallow drilling (AHA-09) with AHA-53 at a depth of 170 m below surface. AHA-52 intersected this zone with 10.6 m grading 0.32 g/t Au, 75.6 g/t Ag, 1.67% Zn and 0.11% Cu.
Alexander Massoud, President and Chief Executive Officer of Alexander Nubia stated: “These encouraging diamond drill results for Hamama East are an excellent complement to the trench and diamond drill results from the Gold-Oxide Cap at Hamama West and especially encouraging are the higher copper values at depth. Combined with previous drill data from Hamama, they support our strong belief that the 3,000 metre mineralized strike length of the Main Horizon, is a manifestation of substantially wider and higher-grade mineralization at depth.”

Table 1: New Drill Assay Results for Hamama East. MH=Main Horizon with zinc-copper-gold-silver-mineralization. Lower cut of 0.2% Zn applied to base metal-rich zones. Lower cut of 0.2 g/t Au applied to gold-silver-mineralized footwall. Reported intervals are 85-100% true width. Zero internal waste within reported intervals. Weighted averages were calculated for reporting purposes. AHA-49 to AHA-53: Au by Fire assay and Ag, Cu, Zn, Pb by atomic absorption. AHA-54: Ag, Cu, Zn and Pb by ICPMS. Intervals not assayed for lead are indicated by ‘na’. Only selected samples were assayed for lead; more samples may be re-assayed for lead.
This phase of the drill program focused on the Main Horizon at Hamama East (see Figure 1 plan view map of Hamama), previously tested only by shallow drilling to maximum vertical depth of 62 m (AHA-09). Sampling of the surface oxide at Hamama East indicated the oxide contains gold, copper and zinc mineralization (see news release April 14, 2015) averaging 33.3% Zn, 0.85% Cu, 0.46 g/t Au and 8.7 g/t Ag (based on nine oxide grab samples collected from within ancient mine workings that pit the oxide ridge).
New diamond drill holes AHA-49 to AHA-54 were drilled at 100 m to 200 m drill spacing perpendicular to the Main Horizon (the main mineralized trend). Multiple zones of zinc-copper mineralization have been identified by northwest of the Main Horizon and a gold-and silver-rich zone occurs in the Main Horizon at the structural footwall. The mineralized zones increase in width from surface down-dip to AHA-53.
Exploration Manager Danae Voormeij describes the drill intercept in AHA-53 of 46.5 metres at 1.67% Zn and 0.11% Cu as “very exciting, since vertical zonation, where zinc grades into copper at depth, is a common feature of most VMS deposits.”
Based on this set of new drill results, the Main Horizon at Hamama East can now be traced from the mineralized oxide at surface, across strike for 450 m (see Figure 2 for long section) to a down-dip extension of 170 m vertical depth (see Figure 3 for cross section). The system is open along strike and down-dip.

ABOUT HAMAMA GOLD-RICH VMS DEPOSIT
Hamama is located within a northeast-trending gold-copper belt that extends for 40 km across the Company’s Abu Marawat Concession. The Main Horizon of Hamama has a strike length of 3 km and is divided into three main zones; Hamama West, Hamama Central and Hamama East (see Figure 1). Mineralization at Hamama crops out at surface, and at Hamama West is deeply weathered into a soft and friable oxidized blanket (the Gold-Oxide Cap), which extends over 900 m in strike length and extends to an average vertical depth of 35 m. Preliminary metallurgical (bottle-roll) test results on the Gold-Oxide Cap returned up to 92.2% gold recovery from oxide (see January 13, 2015 News Release).
About Alexander Nubia International Inc.:
Alexander Nubia (TSX-V: AAN) is in the business of exploring for and developing of potentially economic gold, copper and zinc deposits in the Central Eastern Desert of the Arabian Nubian Shield (“ANS.”) The Company’s 100%-owned concessions, Abu Marawat and the Fatiri, between them cover 2,772 km2 of underexplored ground. Evidence of gold and copper mining in the concessions dates the many surface workings to pre-historic (Copper Age) and Old Kingdom (Pharaonic), through Ptolemaic and Roman and into Early Arab times. Three historic gold mines occur within the two concessions: British miners produced gold at Sir Bakis, Semna and Abu Zawal into the 1920s. None of these mines have been drilled to date.
The Abu Marawat and Fatiri Concessions are underlain by a Proterozoic-aged Pan-African greenstone belt of the ANS. The ANS also underlies the Red Sea and large parts of Saudi Arabia, The Sudan, Eritrea and Ethiopia. Significant VMS deposits in the ANS include Barrick [TSX: ABX] and Ma’aden 50:50% JV of Jabal Sayid in Saudi Arabia; Nevsun [TSX: NSU] Bisha Main and Harena in Eritrea; La Mancha’s Hassai and Hadal Awatib in the Sudan and Sunridge [TSX: SGC] Emba Derho, Debarwa and Adi Nefas in Eritrea. The Company’s Hamama gold-rich VMS shares many key geological similarities with these major VMS deposits.
Much of the gold-vein mineralization in the ANS is of the orogenic, quartz-carbonate-type and is associated with major NNW and NE trending shear-zones. Alteration includes epidote (distal), black chlorite (intermediate) and feldspars-sericite-pyrite-quartz (proximal). Similar geological settings to the ANS include the greenstone belts of the Yilgarn of Western Australia, the Birimian of West Africa and the Abitibi in Quebec, Canada.
The Company’s land package, located 350-400 km southeast of Cairo, includes expanding infrastructure; direct access to two four-lane highways, railway right-of-way, multiple high-voltage (capacity 220kV) power lines, a water pipeline and nearby major cities: Qena, on the Nile River, 70 km to the west, and Port of Safaga, on the Red Sea, 50 km to the east.
Sample Collection and Processing/ALS laboratory Procedures and Analysis/QA and QC:
Drill core sample preparation at Alexander Nubia’s exploration camp includes crushing samples in a jaw crusher and riffle-splitting the product. Then, duplicate 200-gram split samples are placed into kraft paper bags, one of which is sent to the Egyptian Mineral Resource Authority (“EMRA”), which retains duplicates of all samples in its permanent storage facility south of Cairo. Crushed reject samples are stored at the Company’s Abu Marawat camp. Crushed samples are sent by courier to ALS Minerals (“ALS”) in Romania, an ISO-certified laboratory, for final processing and assay analysis. Analytical procedures at ALS involve fine crushing and pulverizing to better than 85% passing minus 75 microns of the sample. A 30-gram pulp sample is taken for gold analysis by fire assay. Cu, Zn and Ag are analyzed by atomic absorption following an aqua regia digestion. Quality control and assurance are maintained by inserting a standard, duplicates or blank sample at random, averaging one quality-control/assurance sample per 15 core samples.
