Alexander Nubia Reports 46 m grading 2.92 g/t gold and 50.2 g/t silver from Deep Trenching Program at its Hamama VMS Deposit, Egypt
* Deep Trench 86 (DT-86) returned assays over 46 m grading at 2.92 g/t gold, 50.2 g/t silver, 0.1% copper, and 0.18% zinc.
* Deep Trench 88 (DT-88) returned assays over 32 m grading at 0.58 g/t gold, 15.9 g/t silver, 0.38% copper, and 1.94% zinc.
* Deep Trench 89 (DT-89) returned assays over 44 m grading at 0.79 g/t gold and 5.9 g/t silver, including 4 m grading at 2.19 g/t gold and 6.0 g/t silver and also including 6 m grading at 1.31 g/t gold and 9.5 g/t silver, with 1.01% copper, and 1.02% zinc.
* Deep trenching tested two sub-parallel VMS lenses located stratigraphically 400 hundred metres below the Main VMS Horizon; these lenses contain highly anomalous values in base metals.
* Further results are pending and expected shortly.
September 5, 2012, Toronto, Ontario. Alexander Nubia International Inc. (TSX-V: AAN) is pleased to announce additional results from its continuing, deep-trenching program from the Western VMS Zone at the Hamama gold-zinc-copper-silver volcanogenic massive sulphide (VMS) project in Egypt. These significant results strongly correlate with and expand on previously reported shallow trenching in the Western VMS Zone (see Table 1). Two new VMS lenses located stratigraphically 400 hundred metres below the Western VMS Horizon have been tested and contain highly anomalous values in base metals. The Hamama VMS deposit has a broad exposed gossan similar to those in other major VMS deposits in the Arabian-Nubian shield. The Main VMS Horizon (which contains the Western VMS Zone) has been traced on surface over 3,000 metre along strike with an extensive mineralized footwall alteration and stringer zone, and stacked VMS lenses beneath the Main VMS Horizon.
Mr. Alexander Massoud, CEO commented, "These are excellent results; the Hamama VMS deposit is likely to be a game-changer!" He also stated, "Our confidence is further supported by the quality of VMS deposits in the Arabian-Nubian Shield that are in production and the recent acquisition of La Mancha Resources for $493 million, primarily for the Hassai VMS deposit in Northern Sudan. Given that other VMS deposits in the Arabian-Nubian shield, such as Jabal Sayid, Hassai and Bisha extend to at least 200 metres depth and with a VMS gossan traced 200 - 1,200 metres along strike - the mineralization that has been identified in the deep and shallow trenching in the Western VMS and other zones is extremely encouraging."
Hamama Deep-Trenching Program
As announced in March 26, 2012, a shallow-trenching program (10-15 cm below surface) discovered the Western VMS Zone, a gold-silver-rich gossan zone with a core 650 m along strike and averaging 60 m wide that contains relatively uniform mineralization averaging 1.15 g/t gold and 19.4 g/t silver, with minor base-metal values. Initial deep-trench results expand on the results of the shallow trenching; four deep trenches (DT-85, DT-86, DT-87, and DT-88), each near a shallow trench, yield generally moderately higher values in both precious and base metals than the corresponding shallow trench. As the rocks are dipping steeply to the northwest, widths in the trenches, which are mainly subhorizontal to gently inclined to the north, are from 3-15% greater than true widths of the units, depending on the local dip of the rocks and the inclination of the trench. All results reported are for lengths along trenches. Average values reported in Table 1 are for arithmetic averages of the samples in the composite.
DT-89, near the point where the Western VMS Zone is overlain unconformably by the Nubian sandstone, contains narrow zones of similar VMS mineralization as to the east. This VMS zone is interpreted to extend beneath an outlier of Nubian sandstone and is exposed west of the Nubian sandstone cover.
Two sub-parallel VMS lenses (stratigraphically below the Main VMS Horizon) were tested with deep trenching: Deep Trenches (DT-90 and DT-91) are located 400 stratigraphically below the western end of the Western VMS Zone. Alteration of footwall andesite extends up to 500 m further to the north of these trenches.
* Deep Trench 90 (DT-90) returned 48 m with 0.32% zinc with a 6-m section containing zones of VMS gossan returning 1.83% zinc and 0.16% Cu.
* Deep Trench 91 (DT-91), mainly in altered andesite, contained two mineralized zones, one 4-m wide zone in VMS gossan averaging 0.77% zinc and another, 34 m wide in altered footwall andesite, averaging 0.15% zinc.

Hamama Deposit Summary
* Main VMS Horizon traced over 3,000 m along strike and open at both ends. The Main VMS Horizon contains the Western, Central and Eastern VMS Zones
* Stacking of visually identified VMS lenses and feeder zones in the stratigraphic footwall of the Main VMS Horizon within a zone up to 2,000 m along strike:
- As announced in April 23, 2012, a geological mapping program discovered at least 34 individual VMS lenses (and possible feeder zones) in the footwall of the Main VMS Horizon and up to 600 m below it. Some are grouped along certain stratigraphic horizons, and all belong to the hydrothermal system that fed the Main VMS Horizon.
- Deep trenching in four of these lenses returned anomalous base-metal values.
* Stringer-style alteration zones in the stratigraphic footwall of the Main VMS Horizon commonly have highly anomalous values of zinc and moderately anomalous values of gold, silver, and copper. Grades in the footwall stringer zone commonly increase towards the contact with the VMS horizon.
* A number of additional, visually similar alteration zones in andesite have been identified throughout the property.
* In the Western VMS Zone, a mineralized footwall stringer zone has been mapped for up to 800 m stratigraphically below the Main VMS Horizon.
Western VMS Zone
* Deep trenching confirms a mainly broad, at surface, high-grade gold zone: 1,100 m along strike and up to 104 m in width.
- Based on results from shallow surface trenching, it contains a core zone 650 m along strike and averaging 60 m in width with relatively uniform mineralization of 1.15 g/t gold and 19.4 g/t silver.
* Results from four deep trenches suggest that the Western VMS Zone is wider with slightly higher values in precious and base metals compared to the corresponding shallow trenches (see Table 1).
- Locally, 2-m channel samples outside the trenches assayed high-grade gold and zinc
* AHA-CH-3383: assayed 15.35% zinc, 0.828 g/t gold, 12 g/t silver, and 0.24% copper over a 2-metre channel sample within ankerite-rich gossan
* AHA-CH-3375: assayed 10.95 g/t gold over a 2-metre channel sample within VMS gossan
Central VMS Zone
* Drilling and surface trenching confirm a relatively uniform grade and width of high-grade zinc and gold mineralization from surface to a depth of 125 m. From drill holes AHA-003, AHA-004, and AHA-005, the widths vary from 14-16 m, grading at 3.03-6.51% zinc, 0.20-0.24% copper, 0.22-0.81 g/t gold and 24.7-44.3 g/t silver.
Eastern VMS Zone
* Extended by 125 m further east for a total length of 500 m and open to the east
* Contains high-grade zinc plus anomalous copper and gold over a width of up to 48 m in the VMS horizon and footwall stringer zone.
Other Gossanous zones
* Valley VMS Zone: About 400 m stratigraphically below the Main VMS Horizon returned 24 m grading 0.46 Cu and 0.17 Zn.
* 400 metres stratigraphically below the Western VMS Zone (Gossan): DT-90 contains a high-grade core of 6 m grading 1.83% Zn and 0.16% Cu, and DT-91 returned 4 m grading 0.77% Zn in VMS gossan and 34 metres grading 0.15% Zn in footwall altered andesite. Both trenches are oxidized and leached and higher base-metal grades are expected at depth.
Combined with previously announced results, these results support the hypothesis that the grade of base metals would increase with depth because of depletion of these elements at surface during weathering. That the grades of precious metals also increase from the shallow to the deep trenches is encouraging. Based on standard VMS models, the highly anomalous base-metal values in the footwall of the Main VMS Horizon are favourable for finding high-grade base-metal zones in the Main VMS Horizon.
The broad extent of alteration (abundant chlorite and pyrite [now oxidized to hematite, geothite, and limonite]) and of the mineralized footwall stringer zone, along with the high-grade gold and silver in the surface VMS gossan are characteristic of large VMS deposits.
Other VMS deposits in the Arabian-Nubian Shield (that extends from Egypt to Ethiopia and eastward into Saudi Arabia) that either are in production or at an advanced stage of exploration/development include:
* Barrick Gold Corp. (TSX: ABX) - Jabal Sayid (Saudi Arabia) - previously controlled by Equinox/Citadel Resources - advanced stage of development
* La Mancha Resources Inc. (TSX: LMA) - Hassai deposit (Sudan) - in production
* Nevsun Resources (TSX: NSU) - Bisha deposit (Eritrea) - in production
* Tigray Resources Inc. (TSX.V: TIG) - Harvest deposit (Ethiopia) - advanced stage of exploration

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 approximately 2 kilograms, is crushed to minus 5 mm and riffle split to 500 g. The 500 g sample is pulverized to a nominal -75 mesh and divided into two halves. Rock and channel samples are processed similar to drill core samples except the diamond sawing stage is skipped. 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 re-pulverizes all 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 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' (generally 20 samples in a batch) is re-analyzed.
About Alexander Nubia International Inc.
Alexander Nubia International Inc. (TSX.V: AAN) is a Canadian mineral exploration and development Company focused on advancing exploration projects in the Eastern Desert in Egypt. The Company holds two exploration concessions: Abu Marawat and Fatiri, which cover areas of 1,027 km2 and 1,745 km2, respectively. The Abu Marawat Concession contains two principal deposits: the Hamama volcanogenic massive sulphide ("VMS") deposit and the Abu Marawat gold-copper mesothermal vein deposit. Priority and resources have been allocated to the Hamama deposit based on recent discovery of a broad zone of VMS gossan at-surface containing high grade gold, an extensive and mineralized footwall stringer zone and excellent first-stage diamond drilling results. The Abu Marawat Technical Report estimates an inferred mineral resource of 397,000 ounces of gold and gold-equivalent(1). With approximately $6 million in direct expenditures on the Abu Marawat deposit, this equates to a discovery cost of $15 per gold-equivalent ounce. With only 50% of the available strike length drilled to an average depth of 200 metres, management of the Company believes that this allows substantial upside for increasing the resource through a modest drill program.
Further enhancing corporate value is a prospective land package containing several quality targets and deposits representing past producing gold mines and historical workings, all within a 35-kilometre radius and near to seaport, railway, electricity grid, international airport and paved highways.
(1) Gold-Equivalent Calculation
Management has used the following to determine the inferred mineral resource of 397,000 ounces of gold plus gold equivalent:
As disclosed in the Abu Marawat Technical Report, the Abu Marawat deposit inferred mineral resource is: 2.9 million tonnes at an average grade of 1.75 g/t Au, 29.3 g/t Ag, 0.77 % Cu and 1.15 % Zn, containing 162 thousand ounces Au, 2.7 million ounces Ag, 49 million pounds Cu, and 73 million pounds Zn. The gold equivalencies of silver, copper, and zinc are based on the metal prices used in the NSR model as follows: Au US$1400/ounce, Ag US$26/ounce, Cu US$3.50/pound and Zn $1.15/pound.
