Alexander Nubia confirms gold-silver mineralization from the deepest drill hole at Hamama, VMS and continues to intersect semi-massive sulphide mineralization:
Hole AHA-25 returned 51.6 metres grading 1.12 g/t gold and 21.8 g/t silver (AuEq 1.53 g/t) including 12.6 metres grading 2.40 g/t gold and 30.8 g/t silver (AuEq 2.98 g/t)
* Drill holes AHA-12 to -26 confirm significant gold, silver and zinc grades and widths in the footwall
* Mineralization extends to 150 metres vertical depth (AHA-26)
* Significant intervals of high-grade gold, silver and zinc shoots
February 27, 2013, Toronto, Ontario. Alexander Nubia International Inc. (TSX-V: AAN) is pleased to announce the results from a fence of drill holes at its recent discovery, the Hamama volcanogenic massive sulphide (VMS) deposit in Egypt's Eastern Desert. A drill program in the Western VMS Zone (AHA-12 to AHA-26 minus AHA-20) confirm that the gold-silver mineralization extends from surface to a depth of at least 150 metres; drilling has tested a strike length of only 400 metres in this zone. Other major VMS systems in the Arabian-Nubian Shield have a known depth extension of 600 to 800 metres, which supports the possibility of additional depth extension at Hamama.
The Hamama VMS deposit contains a steeply dipping, overturned iron-rich gossan and ankerite-rich exhalite (the Main VMS Zone) that is traceable along strike on surface for 3,000 metres. The style and size of precious and base-metal mineralization, the presence of a gold cap, and drilling results to-date indicate that Hamama has similar characteristics to other major gold-rich VMS systems in the Arabian-Nubian shield.
Chief Executive Officer, Alexander Massoud said, "The targeted drill program of 1,450 metres initiated in October 2012 yielded exceptional results. It exceeded our expectations by confirming in the Western VMS Zone a gold cap identified in deep trenching, identifying a broad zone of disseminated gold-silver mineralization in the footwall to a depth of at least 150 metres, including intervals up to several metres thick of high-grade gold-silver-zinc; and in the Central VMS Zone intersected at depth, the mineralized unit which shows continuity of grade and width with a fence of holes nearer surface." He further commented, "With over 2,600 metres of available strike length yet to be adequately tested by drilling, we are very excited about Hamama's potential and the next stage of exploration."
V.P. of Exploration, Dr. John Payne said, "These results confirm that Hamama is a significant precious-metal-bearing VMS system and warrant further drilling along strike and down dip in both the Western and Central VMS Zones. The significant positive correlation in the Western VMS Zone between trench results and drilling warrants a re-evaluation of trench results in other parts of the property not yet tested by drilling. In summary, we believe that, as well as the known drill targets, additional high-quality drill targets can be generated with detailed mapping and geophysics, both along strike in and just below the Main VMS Zone."
Hamama VMS Exploration Highlights
Main VMS Horizon (includes Western, Central & Eastern Zones)
* Significant strike length and potential to expand: Trenching, mapping and drilling confirm the Main VMS Horizon consists of a continuous mineralized unit that was formed along and just below the seafloor; it has been traced along strike on surface for 3,000 metres. For comparison, the strike length of the principal deposit within other major VMS systems include: 1,100 metres (Bisha VMS, Eritrea), 2,500 metres (Hassai, Sudan) and 300 metres (Jabal Sayid, Saudi Arabia).
Central VMS Zone (previously reported)
* High-grade gold-zinc mineralization continues at depth: AHA-20: 170 metres down-dip from the surface outcrop and 23 metres down-dip from the previously deepest hole on the section (AHA-05), returned 11.3 metres grading 5.27% zinc, 1.18 g/t gold, 69.8 g/t silver, and 0.19% copper (AuEq 2.48 g/t gold-equivalent [considering only gold and silver]), including 7.60% zinc, 1.36 g/t gold, 90 g/t silver (AuEq 3.04), and 0.27% copper over 7.5 metres (see the cross-section in Figure 1.3). As well, trenching along the surface traces of drill holes yielded the following results: AHA-09: 28 metres grading 1.04 g/t gold, 20.1 g/t silver, 0.3% copper, and 7.61% zinc, and AHA-11: 24 metres grading 1.01 g/t gold, 40.3 g/t silver, 0.1% copper, and 1.83% zinc.
Western VMS Zone
* Continuity of high-grade semi-massive sulphide mineralization below the gold cap: AHA-15 and -16 (Fig 1.4), AHA-21 and -23 (Fig 1.5), and AHA-24, -25, and -26 (Fig 1.6) intersected a disseminated gold-silver mineralized zone 40 - 100 metres wide that includes high-grade gold-silver and zinc intervals several metres in width.
* 100% of the drill holes in the Western VMS Zone intersected mineralization. The results demonstrate the mineralized unit outlined in trenches continues at depth in the area tested by drilling (AHA-12 to AHA-26) and is open down dip.
* Gold-silver cap. Trenching identified an oxidized gold-silver mineralized zone (gold cap) 650 metres along strike and up to 114 metres in width within the 1,300-metre-long Western VMS Zone. Drilling confirms that at depth the gold-silver mineralization extends at least 400 metres along strike and is open to the west and east and at depth.
Eastern VMS Zone (previously reported)
* The Eastern VMS Zone is 500 metres along strike and returned the following trench assay results:
T-24 28 metres grading 1.14 g/t gold, 19.7 g/t silver, 0.09% copper and 2.11% zinc
and 24 metres grading 1.23 g/t gold, 21.2g/t silver, 0.10% copper and 2.27% zinc
T-25 48 metres grading 0.76 g/t gold, 24.8 g/t silver, 0.14% copper and 3.61% zinc
T-46 78 metres grading 0.26 g/t gold, 9.4 g/t silver, 0.08% copper and 1.37% zinc
Other VMS Horizons
* Mapping and trenching identified additional zones north of the Main VMS Horizon that could represent stacking of VMS units - reinterpretation of earlier results pending

Qualifying Person
The technical information contained in this news release was prepared or reviewed under the direct supervision of Mr. Ralph Gonzalez (P.Geo.), Alexander Nubia Inc.'s Project Manager for exploration in Egypt. Mr. Gonzalez is a qualifying person under National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101").
Alexander Nubia employs an on-site sample preparation facility where core is diamond sawed into two equal halves; and one half of the core is returned to its core box for permanent, on-site storage and the other half, weighing approximately 2 kilograms, is crushed to minus 5 mm and riffle split to 500 g. The 500 g sample is divided into two halves. One half is delivered to the Egyptian Mineral Resource Authority for storage and the other half is shipped for analysis to the ALS Minerals laboratory in Romania. ALS Minerals is an internationally recognized and accredited analytical facility. ALS pulverizes the entire samples to insure the samples are homogenized and removes a one-assay/ton cut (approximately 30 grams) for gold analysis followed by an atomic absorption finish using industry-accepted fire-assaying techniques. In addition, a 5-10 g sample is removed for Ag-Cu-Zn analysis by atomic absorption after digestion in aqua regia. Over-range copper (>10,000 ppm), zinc (>10,000 ppm) and silver (>100 ppm) are re-analyzed using readjusted atomic absorption spectrometry (AAS) techniques. Selected samples are determined by inductively coupled plasma spectrometry - atomic emission spectroscopy (ICP-AES) after a four-acid digestion for 'near-total' digestion. This technique scans a total of 33 elements. A quality control program consisting of insertion of blanks and analytical control standards has been implemented to monitor laboratory performance; this is in addition to ALS's internal QA/QC program. Discrepancies have been few, and when discovered, the 'laboratory batch' (usually 20 samples in a batch) is re-analyzed.
About Alexander Nubia International Inc.
Alexander Nubia International Inc. is an established Canadian mineral exploration company that has operated in the Eastern Desert of Egypt since 2007. It is committed to identifying, focusing on, and advancing gold and base-metal projects in the Arabian-Nubian Shield (ANS), which is known for the quality of its VMS deposits.
The Company holds a highly prospective land package, consisting of two exploration concessions, Abu Marawat and Fatiri, which cover areas of 1,027 km2 and 1,745 km2, respectively. These have an established history of mining dating back to the Pharaonic era, with three past-producing gold mines and four major prospects. The land package is enhanced by excellent and nearby infrastructure, which includes access to highway and railway, a high-capacity electricity grid, and nearby major cities: Qena, on the Nile River, and Port of Safaga, on the Red Sea.
The Company is focused on exploration within the Abu Marawat Concession, which contains its two main properties, the Abu Marawat mesothermal vein deposit, with an NI 43-101-compliant inferred gold-copper-rich resource, and the Hamama volcanogenic massive sulphide (VMS) deposit.
Presently, the Company is advancing the Hamama VMS deposit where excellent first-stage drill results have intersected high-grade semi-massive and massive sulphide mineralization, a broad zone of VMS gossan at-surface containing high-grade gold and silver (a "gold cap"), and an extensive mineralized footwall stringer and breccia zone.
