Alexander Nubia Adds Targets to Current Diamond Drilling Program at Hamama: Grab Sampling Indicates a Mineralized BIF and up to 3.49% Copper and 46.9% Zinc from Oxide
14.04.2015 | FSCwire
Toronto, Ontario (FSCwire) - Alexander Nubia International Inc. (TSX-V:AAN) (the “Company”) is pleased to report assay results from surface grab sampling at its wholly-owned Au-Cu-Zn-Ag Hamama Project. The sampling program of oxide mineralization and Banded Iron Formation (“BIF”) along the 3 kilometre strike length of Hamama has identified a number of new polymetallic and high-grade gold and silver targets that have been incorporated into the ongoing diamond drilling program of the Main Horizon, which commenced March 23rd, 2015 (See News Release March 31, 2015).HIGHLIGHTS:
- Hamama Central – Oxide sampling averages 1.06% copper and 12.59% zinc; BIF sampling averages 2.76 g/t gold, 62 g/t silver and 3.55% zinc
- Hamama East – Oxide sampling averages 0.85% copper and 33.29% zinc; BIF sampling averages 1.27 g/t gold and 33 g/t silver
- At the newly identified Northeast Copper Trend, grab sampling of BIF includes 0.94% copper
Alexander Massoud, President and Chief Executive Officer of Alexander Nubia stated: “The prospectivity of the Hamama Project has been further enhanced by these multiple high-grade oxide samples from Hamama Central and Hamama East. Also, of particular interest is the indication that the BIF along the Main Horizon contains precious and base-metal mineralization, which represents a broader drill target not previously considered.” Mr. Massoud further commented: “The results from this sampling and mapping program have added new targets to our ongoing drilling program, which is currently focused on the Oxide Gold Cap at Hamama West and the associated sulphide mineralization directly below it.”
Surface grab sampling at the Hamama Project tested near-surface oxide material from Hamama Central and Hamama East, as well as the BIF in the immediate structural footwall of the Main Horizon. Nineteen (19) grab samples, including several 8 to 10 kg bulk grab samples, were collected from nine excavations in the oxide zone at Hamama Central and Hamama East. Assays returned an average of 0.46 g/t Au, 8.67 g/t Ag, 0.85% Cu and 33.29% Zn for oxide material from Hamama East, with high values of up to 1.67% Cu and 46.9% Zn. For Hamama Central, assays returned an average of 0.58 g/t Au, 32.8 g/t Ag, 1.06% Cu and 12.59% Zn, with high values of up to 3.49% Cu and 31.9% Zn. Table 1 lists the results for the oxide sampling.
BIF grab sampling took place along the 3 km strike length of the Main Horizon, where 47 grab samples of BIF were collected; 6 from Hamama West, 11 from Hamama Central, 27 from Hamama East and 3 from the new Northeast Copper Trend (See News Release February 3, 2015). Tables 2, 3 and 4 list the best results from the BIF sampling.
Currently, diamond drilling is ongoing and aims to evaluate the Gold Oxide Cap at Hamama West and the upper part of the sulphide mineralization directly beneath it (See Figure 1). At the same time, drilling is assessing the potential for additional mineralization hosted within the adjacent BIF.
UPCOMING RESULTS
1. Assays are pending from the first batch of drill core samples (Holes AHA-027 to AHA-030 in Hamama West); these holes are intended to evaluate the continuity, depth and grade of the oxidized zone.
1. The second batch of drill core samples (holes AHA-31 and AHA-32) are intended to evaluate the sulphide mineralization below the oxidized zone and the potential for “blind mineralization” hosted within the BIF in the structural footwall of the Main Horizon.
HAMAMA PROJECT
Hamama is located within a 40-km-long, northeast-trending, gold-copper belt of 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). Hamama West has a 900-m-long gold-silver oxide cap with preliminary metallurgical test results reporting up to 92.2% gold recovery (see January 13, 2015 News Release). Based on copper mineralization, shown in recent trench and surface channel sampling (see January 6 and February 3, 2015 News Releases), Hamama Central is being extended to the northwest and northeast. Both Hamama Central and Hamama East have evidence of copper mining from ancient underground excavations along the oxide horizon.
The Central Eastern Desert has superb rock exposure. Mineralization at Hamama crops out at surface, and is deeply weathered into a soft and friable oxidized blanket, which based on limited drilling extends to an average depth of 35 meters. Broadly speaking, at Hamama West, this 900-metre-long oxide ‘cap’ contains gold and silver; at Hamama Central and East the oxide also contains significant amounts of copper and zinc.
Sulphide-rich mineralization at Hamama weathers into various types of gossan, which have textures that stand out from the usual desert varnish of the host rocks. BIF is highly resistant and has distinct bedding. Although selective by nature, grab sampling along the strike length of such features can be an effective method of determining their mineralization potential at depth. Along with the 138 trenches that have been completed on the project, the results from grab sampling are helping guide the drilling program.

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 on 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.
Abu Marawat and the 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 covers both sides of the Red Sea and 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 some 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:
Grab-sample preparation at Alexander Nubia’s exploration camp includes crushing samples in a jaw crusher and riffle splitting the product. Then, duplicate 300-gram split samples are placed into kraft paper bags, one of which is sent to the Egyptian Mineral Resource Authority (“EMRA”), who 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. Samples are sent by courier to ALS Minerals (“ALS”) in Romania, an ISO-certified laboratory, for final processing (PUL-31) and assay analysis (Au-AA23/25; Cu, Zn, Ag–AA46/47). Analytical procedures at ALS involve pulverizing of the sample to minus 80 mesh. 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 standards, duplicates and blanks at random at an average rate of 1 per 15 samples.
