Earlier results of deep trenching at Hamama VMS in the oxidised and gold-silver-mineralised cap rock are as follows:

(1): Gold equivalent (AuEq) calculated using the 12-month trailing average for Au and Ag through 2014-05-18, US$ 1292.27/oz Au and US$ 20.41/oz Ag). Using a ratio of US$Au:US$Ag =63 (assuming 100% recovery and no NSR), the AuEq formula is AuEq = (Au g/t + Ag g/t /63). Cautionary note: these figure will change over time. Source: Kitco.com
Dr. John Payne, VP of Exploration stated, "Given that most VMS deposits globally have some form of overburden, the high gold-silver grades at surface and known dimensions of the mineralised cap at Hamama (with a potential to expand) are exciting". Dr. Payne further commented, "Results from a deep trench are as valuable as those from a drill hole; a sample from a trench generally is larger (and thus probably more representative of the mineralization) than a similar length of sample from a drill hole. A cross-section containing a deep trench and drill holes gives an excellent representation of the zone down to the depth of drilling. One objective in this program is to continue with deep trenches in areas of favourable geology, potentially extending the width and strike of the gold-silver cap. We look forward to the upcoming technical results."
Trenching also is planned to test the western strike extension of the Western VMS Zone and will increase the density of trenches in the Central and Eastern VMS Zones. As well, reconnaissance mapping and sampling are being carried out in two nearby historic showings, Bohlog and Sir Bakis, which in previous preliminary studies by AAN had produced high gold values and favourable wallrock alteration.
The Present Work Program includes:
At Hamama VMS
1) Exploration by trenching for strike and width extension of the oxidized gold-silver cap in the Western VMS Zone;
2) Infill trenching to give a density of one cross-section trench along the strike of the Western VMS zone.
3) Exploration by deep trenching along surface traces of mineralized zones defined by drilling; shallow trenches in some of these zones contain high gold-silver values.
4) Exploration by trenching within the Central and Eastern VMS Zones
5) Identification of areas with favorable near-surface mineralization to be further assessed by geophysical surveys
6) Identification of areas with favorable near-surface mineralization to be further tested by drilling
7) Metallurgical testing to establish representative gold-silver recovery rates from cyanide-soluble gold and silver in the oxidized gold-silver cap.
Other areas
At Bohlog, geological mapping and surface sampling is being carried out in a broad area containing auriferous quartz veins and sericitic alteration. In a reconnaissance study in 2011, several samples collected from a zone up to a several hundred metres long gave gold assays from 2 to 18 g/t. Two other nearby zones of significant hydrothermal alteration at Bohlog have been visited briefly and are conspicuous on the satellite imagery and warrant further exploration.
At Sir Bakis, preliminary geological mapping and sampling is being carried out along a prominent auriferous quartz vein with a strike length of at least 500 metres and a widths of up to several metres. Several other zones of shearing and quartz veins along strike of the main zone will also be examined.
About Alexander Nubia International Inc.
Alexander Nubia (AAN: TSX.V), is an Egypt-focused multi-commodity (gold, copper, zinc, and silver) exploration and development company. It is focused on exploration within the Abu Marawat Concession, which contains its two main properties, the Hamama volcanogenic massive sulphide ("VMS") deposit and the Abu Marawat mesothermal vein deposit, the latter with an NI 43-101-compliant inferred gold-copper-rich resource. In addition, Alexander Nubia's two large concessions, which have a long history of gold and copper mining dating back to the Pharaonic era, include three past-producing gold mines that were in operation during the 20th century.
The Hamama VMS has numerous characteristics that are similar to those of other major VMS deposits in the Arabian Nubian Shield: Bisha (Nevsun Resources), Hassai (La Mancha), Jabal Sayid (Barrick Gold). Drilling at Hamama intersected high-grade semi-massive and massive volcanogenic sulphide mineralization; this contains a broad zone of VMS gossan with high-grade gold and silver (an oxidized "gold cap") above a primary zinc-gold-silver-rich exhalite horizon, and an extensive mineralized footwall stringer and breccia zone. The Gold Cap extends 650 metres along strike and averages 43.8 meters wide grading 2.05 g/t gold and 44.7 g/t silver. Drilling has confirmed an oxidized zone extending 30 to 45 metres in depth.
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.
Qualifying Person
The technical information contained in this news release was prepared or reviewed under the direct supervision of John Payne (P.Geo.), Vice President of Exploration for Alexander Nubia Inc. Dr. Payne 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; one half of the core is returned to its core box for permanent, on-site storage and the other half, weighing 2 kilograms, is crushed to minus 5 mm and riffle-split down 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.
