Strait Samples 4.69% Lead, 36.8 g/t Silver over 28 metres at Tastani


TORONTO, ONTARIO--(Marketwired - April 29, 2014) - Strait Minerals Inc. (TSX VENTURE:SRD) is pleased to report assay results from a program of channel sampling conducted in February, 2014, at the Tastani polymetallic zone on the Company's Alicia property in Peru.

Tastani, which was essentially unexplored until 2012, consists of breccias and mantos mapped over an area of approximately 1,500x1,000 metres. Two lines of channel sampling (which includes country rock cropping out between the mantos and breccias) were completed over total lengths of 180 metres and 150 metres across the apparent northeast-southwest trend.

Highlights include intervals of:

  • 17 metres in Channel 1 averaging 4.95% Pb, 43.3g/t Ag, 0.43 % Zn, 0.12% Cu and 0.73g/t Au
  • 28 metres in Channel 2 averaging 4.69 % Pb, 36.8g/t Ag, 0.39% Zn, 0.09% Cu and 0.04g/t Au

Mineralization remains open to the northeast and southwest and appears to be controlled by second order faults related to a regional-scale fault across the northern part of the zone. The mineralization is contained in a combination of mantos (typically 1.0-2.5 metres wide and up to eight metres) and vein breccias (1.0-2.0 metres and up to six metres wide) in variably altered limestone. The density of mantos and breccias varies within the host limestone. In some areas, mantos are spaced less than six metres apart, increasing to ten (or more) metres in places, and often have thin mineralized bands/veins between them. Vein breccias with regular density and stockwork composed of veins in several directions also occur in the area.

"Tastani is a significant discovery," said Strait President Jim Borland. "We need to determine the full extent of the deposit, but the grades we have seen to date are encouraging. Further work is warranted, including drilling to test the depth potential."

Strait's initial work in 2012 consisted of 73 panel samples taken approximately every 100 metres (see news release of Dec. 10, 2012) from mantos and breccias at Tastani (excluding rock between sampled areas). Results included:

  • 2.5 metres grading 2.1g/t Au, 169g/t Ag, 16.11% Pb, 12.66% Zn and 0.39% Cu
  • 1.5 metres grading 1.5g/t Au, 989.0g/t Ag, 18.24% Pb, 0.57% Zn, and 2.85% Cu
  • 2.0 metres grading 2.6g/t Au, 110g/t Ag, 11.75% Pb, 5.37% Zn, and 0.50% Cu
  • 3.0 metres grading 1.5g/t Au, 93.6g/t Ag, 9.03% Pb, 0.96% Zn and 0.55% Cu.

Tastani is in the southeast portion of Strait's 100% owned Alicia property which lies approximately 500 km southeast of Lima.

Quality Control and Quality Assurance

All sampling was supervised by Strait Minerals personnel. Samples are placed in plastic sample bags that are closed with single use plastic ties. Samples are securely stored in a locked room prior to transportation to Cusco by Strait Minerals personnel. Samples are sent to AcmeLabs in Lima for preparation before being couriered to the AcmeLabs facility in Santiago for assay. Acme's Santiago facility is an ISO 9001:2000 registered laboratory. Samples are analyzed for gold by fire assay followed by atomic absorption spectroscopic (AAS) finish and by gravimetric finish for samples exceeding the upper limit of analysis (over limit). Silver, lead zinc and copper, together with 30 other elements, were assayed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) following aqua regia dissolution. Samples with values above the upper limit for the ICP-AES technique were re-assayed by atomic absorption (AA). Strait Minerals routinely carries out a program of quality assurance/quality control (QA/QC) that includes insertion of blanks, standards and duplicates into the sample stream to verify results prior to dissemination

All of the Company's exploration programs are prepared by, or prepared under the supervision of, Dr. Roger Moss, P.Geo., who serves as the Qualified Person as defined by NI 43-101 and is a director of the Company. Dr. Moss has reviewed and approved the technical content of this news release.
