![Alexander Nubia Discovers New Zone at Hamama Gold-Rich VMS Project: AHA-31 Returns 88.4 Metres At 1.11 G/T Gold And 118 G/T Silver](https://www.goldseiten.de/media/goldseiten-news.jpg)
Highlights:
- Drilling AHA-29 and AHA-30 into the Gold-Oxide Cap at Hamama West indicates gold and silver enrichment in oxide from surface to a true depth of 34 metres
- Based on the fence of holes that includes AHA-29, -30 and -31, mineralization increases in width and grade with depth
- Hole AHA-31, targeting primary sulphide mineralization beneath the Gold-Oxide Cap, returned 88.4 metres at 1.11 g/t Au and 118 g/t Ag (2.81 g/t AuEq), including a high-grade intercept of 21.4 metres at 2.56 g/t Au and 573 g/t Ag (10.80 g/t AuEq).
Alexander Massoud, President and Chief Executive Officer of Alexander Nubia stated: “Following a successful deep trenching campaign at Hamama in 2014, this first batch of exciting drill results shows gold-silver mineralization from surface to a depth of at least 160 metres.” Mr. Massoud further commented: “We’re particularly pleased with the intensity of the sulphide mineralization at depth in AHA-31, which intersected two substantial zones of high-grade gold-silver-zinc values. We look forward to the next batch of drill results that will continue to evaluate the Gold-Oxide Cap and primary sulphide mineralization beneath it.”

Using this ratio of US$Au:US$Ag (=69.4) and assuming 100% recovery and no top cut, the AuEq formula is AuEq = (Au g/t + Ag g/t /69.4). Cautionary note: these figures may change over time. Intervals are calculated using a 0.2 g/t Au lower cut.
Ms Voormeij, PGeo and exploration manager for Alexander Nubia, commented: “This hole is the deepest hole on the project and intersected a new style of high-grade mineralization, which may occur elsewhere under the Gold-Oxide Cap. The results from AHA-31 further emphasize the comparison between Hamama and major VMS deposits within the Arabian Nubian Shield. Similarities include an oxidized gold cap and precious-and base-metal mineralization in tabular sheets with a step-wise geometry that increase in size and grade with depth. Such systems are known to extend to depths of over 500 metres; the high-grade zone in AHA-31 was intersected at a true depth of merely 130 metres; there is a lot of blue sky here.”
This initial phase of the drill program has focused on parts of the Gold-Oxide Cap that were untested by previous drilling. Preliminary assay results suggest excellent grade continuity of the Gold-Oxide Cap across this new area of Hamama West (see Table 2). Drill holes AHA-29, -30 and -31 were drilled with HQ diameter core and sub-perpendicular to the strike of the Main Horizon. True widths are estimated to be 80-85% of the reported intervals.

HAMAMA PROJECT
Hamama is located within a northeast-trending gold-copper belt that extends for 40 kilometres across the Company’s Abu Marawat Concession. The Main Horizon of Hamama has a strike length of 3 kilometres 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, over 900-metres in strike length and, based on limited drilling, extends to an average depth of 35 meters. Preliminary metallurgical test results on the Gold-Oxide Cap returned up to 92.2% gold recovery (see January 13, 2015 News Release). Hamama Central contains copper mineralization, as reported from recent trench and surface channel sampling (see January 6 and February 3, 2015 News Releases). Both Hamama Central and Hamama East have evidence of copper mining from ancient underground excavations along the oxide horizon, from which grab sampling returned assays averaging 1.06% copper and 12.59% zinc (see April 14, 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 and copper 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. Several historic gold mines and numerous gold showings and gossans occur within the two concessions.
The Abu Marawat and Fatiri Concessions are underlain by a Proterozoic-aged Pan-African greenstone belt of the ANS, which has been intruded by at least two main ages of granodiorite intrusions. Much of the gold-sulphide mineralization is of the orogenic, quartz-carbonate vein-type and is associated with major NNW and NE trending shear-zones. Alteration includes epidote (distal), carbonate (intermediate) and sericite-pyrite-quartz (proximal). Similar geological settings include the greenstone belts of the Yilgarn of Western Australia, the Birimian of West Africa and the Abitibi in Quebec, Canada.
The ANS includes parts of Egypt, 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 land package, located 350-400 km southeast of Cairo, includes expanding infrastructure; access to two four-lane highways, railway right-of-way, high-voltage (capacity 220kV) power lines, 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 220-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.
