Canadian International Minerals Samples Up To 8.93% Cu, 0.18% Co, 0.15% Bi, 59 g/t Ag, 89 g/t In, and 2.25 g/t Au at Tisová Project
A total of eight samples containing visible sulphides within phyllite were taken from dumps on the property, under the supervision of Thomas Hasek, P.Eng, a Qualified Person and director of the Company. The samples were prepared and analyzed by ALS Chemex in North Vancouver.

The Company is pleased with the results, which are consistent with historical and published reports from previous operators. Absent, however, were significant quantities of PGM's, which had been encountered in previous research. The Company is continuing to compile the extensive amount of data that was acquired during the due diligence program, and will provide an update when the process is completed. Acquisition of the Tisova concession is proceeding under a letter of intent between Canadian International and the two owners of the concession (see news release dated August 3, 2016).
Background on Tisova deposit
Tisova is classified as a Besshi-type Volcanogenic Massive Sulphide (VMS) deposit. Such deposits are often large and, along with copper and cobalt, normally include other recoverable base and precious metals. While historically the deposit was mined primarily for copper, significant concentrations of other base and precious metals have also been identified, though there appears to be no mention of their recovery in any historical documents.
A historic resource was calculated on the unmined portion of the Tisova deposit by the Czechoslovakian government under the Russian classification system as being C1B that was calculated by drilling and underground development (Henley, S., 2004).
This resource was reported as a "preliminary reserves" and was 3,553,000 tonnes of 1.04%, 13.5 g/t Ag, 0.232 g/t Au and 0.019 % Co.

The mineralized bodies at Tisova were concentrated in the three horizons: lower, central and upper. The lower was the most continuous and the central was economically most important. The known length of the lower horizon reaches 1000 m, of which 450 m has been accessed by Helena mine. The mineralized zones are present in forms of irregular layers and lenses of variable size, with typical grades of 0.8 % Cu. The average thickness of lenses at the central horizon ranged 2-6 m, occasionally swelling to 10 m, and exceptionally up to 30 m, with a length of 100-150 m and down dip extent of several hundred meters.
Two stages of drilling exploration took place at Tisova in the 1950's and 1960's, with more than 100 drill holes having been completed by Czechoslovak state mining companies. Drill logs exist, but under the then current technical parameters all core was consumed in assaying. The majority of core was only assayed for copper.
Postwar exploration and development at Tisova prior to the Velvet Revolution (1948-1989) was typically dictated by strategic, political, and military considerations rather than the strictly economic constraints that provide parameters for western style of exploration and development. The geological model was not fully understood and different criteria guided the exploration priorities. An exploration program in the central and southern zone of the deposit was executed between 1971 and 1989, verifying mineralization down to the level of 400 m below surface (level 9 of Helena shaft). Mining was not resumed and the mine was left to flood.
The main ore minerals at Tisova are predominantly chalcopyrite, pyrrhotite, and pyrite, generally accompanied by arsenopyrite, magnetite, sphalerite, bismuth, bismutite, jamesonite, ullmannite, colbaltite, and electrum (Pertold et al 1994).
