Colt Resources Inc. (TSXV:GTP, FRA:P01, OTCPINK:COLTF),  has obtained an update on drilling results obtained from an additional hole drilled at its 100 percent owned Borba exploration concession in southern Portugal.
As quoted in the press release:

The Borba concession, recently reduced to 316.6 km2, is located in the Ossa-Morena zone of the Hercynian basement. The main focus of exploration in the concession is the Miguel Vacas copper deposit, which was mined to a limited extent by open-pit methods in the 1980’s.
Copper mineralization at Miguel Vacas is structurally controlled, hosted by late tectonic breccias related to a north-northwest trending shear zone that cuts through lower-Palaeozoic formations. During historical mining two types of mineralized breccias were distinguished; namely siliceous breccias and schist breccias (Figure 2), with the former being generally higher in copper content. The deposit dips steeply, around 70° east-northeast and is zoned vertically, comprising (1) an upper zone of oxide copper mineralization which can exceed a depth of 70 metres, (2) an intermediate transitional zone and (3) a lower zone of sulphide copper mineralization.
Most historical exploration as well as the historical mining was concentrated in the “main” breccia structure, which can be up to more than 15 metres in true width. Colt has located old historical records referring to other, parallel mineralized breccia structures (Figure 2).

The release additionally states:

The average dip of the mineralized structures is generally 70° ENE with the horizontal plane, which leads to a 50° angle of intersection by a 60° WSW inclined hole such as BOVM-15-002.
All drill core is transported by Company personnel from the drill site to a secure storage facility for logging and sampling. Sampling intervals are defined after core logging and qualitative determination of mineralized contents by visual inspection. The core samples are then cut longitudinally with a diamond saw, one half of the core is sent for analysis, while the other half is retained in the core boxes for future reference.
