This is showing us partly what they are trying to do with the trenching. To see how far they can follow some of these veins to see if they are connected. Where you see the gaps of no samples on the maps, this is partly the reason, the overburden has covered those areas due to the volcanics. It should be reasonable to beleive that this system is all connected under the volcanics.

Below is from Brophy,s report.

The mineralized quartz veins at Teroro have a typical pinch-and-swell structure

referred to as “estructura rosario” (rosary-bead structure) in Peruvian literature.

The amplitude of the pinch-swell structures on the Tesoro property is not

known, as there is always some doubt whether the disappearance of a vein

structure signifies a “pinch-out”, or an interval where colluvial deposits obscure

the vein.

About 20% of the Chance 1 claim is underlain by felsic volcaniclastics of the

Tertiary Sencca Formation. These unconformably overlie the Cretaceous

intrusive rocks and occur mainly in two northeast- to east-northeast-trending

belts. These volcanic belts are probably shallow remnants filling valleys of the

Cretaceous paleotopography. The northern belt separates Zona Canchete from

Zona Central and the southern belt separates Zona Central from Zona Sur. The

Sencca volcanics, which comprise light-colored ash and crystal tuff, are not cut

by the aforementioned dikes or quartz veins, thus signifying that the age of gold

mineralization is post Tiabaya Superunit and pre volcanic. Consequently, it is

most likely that gold-bearing quartz veins are connected beneath shallow

volcanic cover between Zona Canchete and Zona Central, and between Zona

Central and Zona Sur.
