TIREK NORTH (Au, Ag)
Location:
Located in the southern region of Algeria, Tirek North is 320 km south west of the town of Tamanrasset and is approximately 2,000 km south of the town of Algiers in the Saharan desert.
Access: Accessible by road in all seasons with the use of 4 by 4 vehicles.
Land: 98 990 ha
Title:
A prospection permit under exclusive right was granted in June 2008 for a period of one year. The permit is renewable. The property was acquired from the Algerian government through a transparent bidding process.
Geology:
The permit covers the faulted contact zone between archean granulitic rocks of the In Ouzzal mole to the west and proterozoic metamorphic rocks to the east. This contact zone is characterized by the presence of a wide strip (up to 1500 m) of mylonitic rocks that are associated with the north extension of the east In Ouzzal shear zone. The Tirek and Amesmessa gold deposits are located 20 km and 35 km respectively south of Tirek North’s south boundary.
The Tirek deposit contains 630,000 tonnes of ore grading 16.73 g/t Au and the Amesmessa deposit, which is currently put into production, contains 1,040,000 tonnes grading 12.05 g/t Au† In these deposits, the gold, often native, is associated with decimetric to metric quartz veins in mylonitic rocks mineralized with minor sulphides (pyrite, galena and chalcopyrite).
Work:
Exploration work conducted by Romanian and Russian geologists between 1970 and 1972 for Sonarem, an agency of the Algerian government, comprised geological reconnaissance surveys and prospection for gold with detailed geological surveys and extensive trenching and sampling on each gold showing.
Mineralizations and potential:
Exploration work conducted during the period 1970-1972 led to the discovery of several narrow quartz veins mineralized with gold in sheared mylonitic rocks in several gold fields. The most important zones are: Kheima, Zone 12, Zone 13, Zone 17, Syenite showing and Kiouène. Each mineralized field is made up of several quartz veins that are mineralized with pyrite and locally native gold.
The Kiouène gold field comprises 80 quartz veins, of which 25 are auriferous. The auriferous veins are made up of dark gray quartz containing pyrite, hematite, chalcopyrite, galena and native gold. The width of the auriferous vein varies between 0.1 and 0.5 m and their length is generally less than 200 meters. The grade is highly variable with a maximum of 196.4 g/t Au.
The Syenite gold field represents a 400 meter quartz vein disposed in echelons of syenite, in which two portions assay respectively 10.73 g/t Au over a length of 106 m and a thickness of 0,32 m and 9,51 g/t Au over a length of 34 m and a width of 1.94 m.
Zone 13 contains at least 11 auriferous quartz veins. The auriferous veins generally are less than 100 m long with thickness varying between 0.3 and 2.0 m. The best assays were obtained in vein F10 that grades 16.4 g/t Au over a length of 125 m and a width of 0.3 m and in vein F2 that grades 15.8 g/t Au over a length of 120 m and a width of 0.6 m.
The Kheima showing consists of a discontinuous quartz vein, 500 m long, in which a 75 m portion contains grades which vary between 5.0 and 66.78 g/t Au for an average of 21.0 g/t Au over a width of 2.4 m. The vein material is made up of white to dark grey quartz with small amount of pyrite, galena and iron oxides and native gold in brecciated oxidized zone.
The potential to find vein-type gold deposits similar to the Amesmessa and Tirek deposits is excellent considering the extent of the hosting mineralized fault structure.
A 43-101 compliant geological evaluation report is currently being produced and will be released once completed.
