Tchintaby Well Project
(E52/1882 and ELA52/1959) - 80% Encounter, 20% Avoca
The Tchintaby Well Project covers over 750km 2 and is being targeted for high grade SEDEX zinc mineralisation, similar to the Century and McArthur River deposits in Eastern Australia.
Encounter has completed 3D modelling of ground gravity data covering a 40km segment of the Flint Hill Lineament. This lineament is interpreted to represent the location of a long lived basement structure and possible conduit for mineralising fluids. In total, six areas of excess mass have been defined in the Bouguer gravity image adjacent to the Flint Hill Lineament (Figure 1).

Drilling in the mid 1990s by CRA Exploration intersected an extensive area of low grade Zn-Cu-Ag mineralisation extending laterally over an area 8km by 5km. Holes drilled within the mineralised area returned intersections in the order of 10-15m thickness, grading 0.5-1% Zn, 500-1000ppm Cu and 5-15g/t Ag.
It appears that the low grade Zn-Cu-Ag mineralisation drilled by CRA at the Andes Prospect is associated with a cluster of gravity features in the north of the project. Significantly, the holes drilled by CRA have not tested the highest amplitude gravity features (see Figure 2).
