that its Optionee, Tosca Mining, has entered into a contract with Layne De
Mexico SV de SV to undertake a drill program on Alta Vista’s Carol project
located in southern Sonora State, Mexico, and approximately 4 km from the
Piedras Verdes porphyry deposit, Mexico’s third largest copper
producer.
Work is being conducted by Alta Vista on behalf of Tosca. Site
preparation is now underway with drilling expected to commence by the end of
April. The initial drill program will consist of 5 to 7 HQ size holes totaling
500-700 metres.
The drill program is the first ever to be conducted on
the property. The planned drilling will investigate the continuity, extent and
morphology of near surface skarn mineralization occurring within a shallowly
dipping metasedimentary sequence, as well as possible porphyry-style
mineralization at depth. It will focus on the Balde Sur area where previous work
at Carol by Alta Vista identified widespread polymetallic skarn-style
mineralization has been outlined in two mineralized zones: Balde Norte that
measures 700 metres by 180 metres and Balde Sur that measures 1,100 metres by
400 metres. 5 trenches were dug in Blade Norte and12 trenches were completed in
Blade Sur (see news release dated July 10, 2008).
This most recent work
(see news release dated January 27, 2014) re-opened select portions of two of
these trenches in Blade Sur, BS-06 and BS-08, to validate past results in
preparation for a proposed drill program. Continuous chip channel sampling,
conducted at one metre intervals, confirmed the presence of significant
mineralization in both trenches as follows:
Average Grade | |||||
|---|---|---|---|---|---|
Trench | Width (m) | Cu (%) | Ag (g/t) | Zn (%) | Au (g/t) |
BS-06 | 8.0 | 1.06 | 22.5 | 11.87 | 0.26 |
BS-08 | 11.0 | 0.38 | 22.4 | 0.48 | 0.08 |
and | 8.0 | 0.48 | 16.5 | 0.62 | 0.07 |
Additionally, two
grab samples taken from historic workings located in the immediate vicinity of
trench BS-06 (one to the south and one to the north) returned significant high
grade results as follows:
Average Grade | |||||
|---|---|---|---|---|---|
Sample | Width (m) | Cu (%) | Ag (g/t) | Zn (%) | Au (g/t) |
BS-06 N | grab | 7.00 | 94.3 | 34.00 | 0.61 |
BS-06 S | grab | 3.70 | 30.3 | 19.00 | 0.67 |
Samples
from Carol were prepared and analyzed by IPL Inspectorate in their facilities in
Mexico and Vancouver, respectively. Samples generally consisted of 1-3 kg of
material. Gold, silver, copper, lead and zinc were analyzed as part of a
multi-element ICP package using an aqua regia digestion. Over limit samples with
greater than 1% Cu, Pb and Zn were re-analyzed using ore grade detection limits.
Samples with greater than 20% Zn were re-analyzed a second time for using even
higher parameters.
