Mato Bula
The high-grade gold mineralization at Mato Bula is associated with chalcopyrite-rich quartz veins hosted within a silica-sericite-chlorite-pyrite alteration zone. Recent rock chip and trench sampling at Mato Bula delineated a well-defined surface target over 800 metres long including three gold-bearing mineralized lodes (refer to Tigray's news release dated Jan 24th, 2013), within a 2km long geochemical Cu-Au anomalous zone. The lodes from NW to SE comprise the Upper Lode, the Main Lode (main gold artisanal workings) and the Lower Lode, defining a 70 to 85m wide target zone. The five holes at Mato Bula tested part of this target, between 35m and 120m below surface on five drill sections spaced at 60m to 220m apart, with best grade mineralization beneath the base of oxidation.
It is significant to note that the thickest high grade intercepts from the drilling at Mato Bula are on the most southerly and northerly of the five sections drilled and thus the target is open in all directions. Further diamond drilling is required to test this Au mineralization along strike, down plunge and down dip.
Mato Bula North
Mato Bula North is a 200 metre long malachite-rich silica alteration zone (hill) with abundant copper-rich porphyry dikes, and adjacent gold surface targets as defined by soil geochemistry. Significant copper was previously defined at Mato Bula North where Trench 08 chip samples returned nine metres at 0.87% copper (remaining open to the west). Drilling has defined disseminated, stringer, vein and massive sulphide vein style Cu-Au mineralization associated with very intense silica alteration. WMD001 has tested part of the target, but the drillhole required abandonment short of the planned 145 metre final depth. It is interpreted that the hole did not fully test the entire target, as defined from surface showings.
Da Tambuk
New infill soil sampling results and channel sampling from two trenches for Da Tambuk have recently been received (refer to Tigray's news release dated Jan 24th, 2013 for previous results). Da Tambuk is approximately 4km NNE and along strike of Mato Bula. Soil sampling at 40 x 40m has highlighted a 1.5km long >50ppb gold anomaly over an intense sericite alteration zone with variable silica alteration and zones of sulphide. Trenching over the northern end of the soil anomaly has encountered 16m @ 3.95 g/t Au (Trench ADT004 with 2m continuous rock chip channel sampling), including 4m @ 14.53 g/t Au. Multiple trenches over the target are now being completed for follow up. The discovery of high grade mineralization at Mato Bula and Da Tambuk has significantly enhanced the overall prospectivity of the 5.5km trend of mineralization.
Deposit Style
Although exploration is at an early stage, the geological setting with volcanic and volcaniclastic rocks and associated chert and limestone, the associated schistose sericite-chlorite alteration assemblages, and both high-grade gold with lesser, but significant, copper, and thicker zones of lower-grade copper-gold mineralization suggest that this is a deposit style or variant not previously discovered in the Arabian-Nubian Shield in Northern Ethiopia. The Mato Bula prospect occurs in a province in which there are known VMS deposits, and there are both Zn-Pb soil anomalies and barite horizons defined in the vicinity. At this stage further drilling will be required to test the full potential of this system of new prospects.
Quality Control
The planning, execution and monitoring of Tigray's quality control programs at the Harvest project are under the supervision of Jeff Heidema, P.Geo., Tigray's Vice President Exploration. Mr. Heidema is a Qualified Person as defined by National Instrument 43-101. Diamond drill core samples have undergone preliminary preparation at the Acme Laboratories facility in Ankara, Turkey, and are crushed to 80% passing 10 mesh, and pulverized to 85% passing 200 mesh (Acme R200-1000 package). Analyses are conducted at Acme Laboratories in Vancouver, Canada, utilizing Aqua Regia digestion and ICP-ES for base metal and silver analyses. Gold analyses are conducted via Fire Assay Fusion with AA finish, and gravimetric analyses are completed for over-limit samples. Blanks and certified reference standards are inserted into the sample stream to monitor laboratory performance. Duplicate samples are inserted into the sample stream to both monitor laboratory performance and also characterize potential mineralization.
