Ann: TVN Lead-Silver Mineralisation Extended at Sandover Project, page-4

Early days, but finding what they have at surface over such a wide area is promising IMO.

Circling back to the report on Cannington as a point of reference :
The Cannington orebody is located 200 km SE of Mt. Isa (QLD), Fig. 1, and has been in production since 1997. The deposit had a total resource of 43.8 million metric tonnes (pre-mining) grading 11.6 percent lead, 4.4 percent zinc, and 538 ppm silver (Walters et al. 2002) and is currently the largest producer of silver in the world.

The Cannington deposit does not outcrop but is covered by a veneer of Cretaceous mudstones with a thickness varying from a few 10s to over 100 meters.define a large and coherent system envelope with a north-south strike extent of 1,800 m and a maximum (structurally repeated) thickness of 200 to 300 m, extending to depths of over 600 m below surface.

the Northern Zone with 9.1 Mt @ 8.9% Pb, 3.0% Zn and 371 g/t Ag whereas the Southern Zone had 34.7 Mt @ 12.4% Zn, 4.9% Pb and 582 g/t Ag
