Lupoto(Sase) - Permit 2214
100% Tiger Resources
Background
The Sase Project is situated within the Lupoto Permit (PR2214) which covers an area of 293 sq km. The permit is located approximately 10kms to the south of the Kipoi Project and the Sase Copper Project can be accessed by a road that leads directly to Kipoi.
The Company holds a 100% interest in the Lupoto Permit and Aurum sprl has the right to a 1% NSR from any production.
The discovery of mineralization at Sase was one of the outcomes from a systematic regional exploration programme undertaken by the Company over the permit in 2007 and 2008. The results of the programme identified three broad areas (refer Figure 1) within the permit that were interpreted to have the potential to host copper mineralization.
The prospectivity of each of these areas was confirmed by the results of an Aircore drilling programme conducted in 2007 and 2008.
Aircore results at Sase outlined significant copper mineralization over an area of 450m by 50m. High grade copper intersects included 67m @ 2.83% Cu and 0.19% Co (hole stopped in mineralisation) and 51m @ 1.50% Cu and 34m @ 1.15% Cu.
Diamond Drilling
The Company has completed a 25 diamond hole (for a total of 4,294m) drill programme at the Sase Prospect. Significant results from the programme include 107.10m @ 2.37% Cu (including 64m @ 3.27%Cu), 142.75m @ 2.14% Cu (including 73.25m @ 3.33%Cu), 70.30m @ 2.17% Cu, 30.50m @ 2.12% Cu, 38.85m @ 5.23% Cu and 60.50m @ 3.49% Cu.
The drill results have delineated a west-north-west elongated mineralised envelope over a strike of about 600m that varies in width between 50 and 200m. The majority of mineralisation so far tested resides in the oxide zone that extends to 120m in depth. Mineralisation remains open along strike and at depth. The mineralisation (both oxide and sulphide) is hosted in intensely brecciated sedimentary rocks, mainly carbonaceous siltstones, shales and dolomites of the Lower Kundelungu Group associated with a 10km long fault system.
Geology
The Lupoto Permit (PR 2214) sits within the Central African Copper belt and covers a sequence of Kundelungu or Roan Supergroups sediments folded into broad synclinal and anticlinal structures.
East-west and west-northwest to east-southeast fault zones trending at high angles to the fold-axes have led to major displacements of strata during folding and the formation of fault breccias that represent important exploration targets. The Sase Project is located in an area of intersecting splay structures associated with a major project scale fault system, the Sase Fault Zone. Several other analogous geological settings have been identified in other parts of the Lupoto Project area.
Mineralisation
Mineralisation at Sase is hosted in intensely brecciated sedimentary rocks, mainly carbonaceous siltstones, shales and dolomites of the Lower Kundelungu Group. These stratigraphic units are known to host one of the world’s largest Pb-Zn-Cu deposits at Kipushi, 50km west of Lubumbashi in the DRC. Mineralisation appears to be controlled by a set of splay faults that have been traced over a distance of 4 kilometres and are associated with the Sase Fault which is at least 15kms in length.
Copper mineralisation at the Sase Project occurs above and below the base of oxidation. Malachite and azurite to a lesser extent are the principle copper oxide minerals and occupy breccia matrixes and vughs. Chalcopyrite and to a lesser degree chalcocite are the main sulphide copper minerals and occur preferentially in fault breccia matrices, veins and to a lesser extent as stratiform mineralisation. The bulk of the mineralisation identified to date occurs in the oxide zone between 15 and 120m below surface.
The envelope to the mineralisation delineated from diamond drilling projects as an elongated, west-northwest-trending tear-shaped lens to surface. It has a strike extent of about 600m and varies in width between 50 and 200m. The mineralisation is interpreted to be associated with a secondary splay structure off the main east-west fault trend and to be controlled by a fault breccia. Mineralisation remains open along strike and at depth.
Exploration Potential
The geophysical data show that the east-west trending Sase Fault Zone is a very prominent feature of a possibly much larger segmented fault trend with an interpreted strike length of at least 15km. It is likely that the setting for the Sase mineralisation is repeated along this trend and that recurrences of mineralisation are possible. Numerous high grade anomalies along the fault have been identified and require follow up.
The discovery of mineralisation in a region that previously was not known to host any historic copper workings or surface occurrences highlights the potential of the area in general and underpins the value of systematic exploration.
The Company believes further exploration testing of interpreted splay structures along the Sase Fault Zone is necessary as this trend holds significant exploration upside. Very prospective high order geochemical soil anomalies identified with similar structural trends southeast, southwest and northwest of the Sase prospect further add to the exploration potential and discovery upside in the property.
