Orex Announces 33.3 Million Ounces of Silver in an Inferred Resource Estimate for the Boleras Deposit at the Sandra-Escobar Project in Durango State, Mexico
October 31, 2016
Vancouver, October 31, 2016 - Canasil Resources Inc. (TSX-V: CLZ, DB Frankfurt: 3CC, “Canasil” or the “Company”) is pleased to report that Orex Minerals Inc. (TSX-V: REX, “Orex”) has announced a first resource estimate for the Boleras Silver Deposit on the Sandra-Escobar Project in Durango, Mexico, prepared by the consulting firm Mining Plus. The project is being advanced by Orex under an option agreement with Canasil announced on September 15, 2015.
At a “Base Case” of 45 g/t Ag cut-off, the Inferred Resource Estimate yields 9.8 million tonnes (Mt) grading 106 g/t Ag for a total of 33.3 million ounces (M-oz) of silver.

Note: Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the estimated Mineral Resources will be converted into Mineral Reserves. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. The Mineral Resource was estimated by Dr. A. Fowler, MAusIMM, CP (Geo), Independent Qualified Person under NI 43-101. Data was verified by Mr. Michael Collins, P.Geo., Independent Qualified Person under NI 43-101, of Mining Plus Consultants. The Mineral Resource was estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the Standards Committee on Reserve Definitions and adopted by the CIM Council on May 10, 2014. The Mineral Resource is sub-horizontal, outcropping or close to surface, and is therefore expected to be mineable by open pit methods with a low strip ratio. It has reasonable prospects of economic extraction at a cut-off grade of 45 g/t silver. The cut-off grade of 45 g/t silver was estimated using a silver price of $17.50 per ounce. Drilling results as of 7 October 2016 are included. The numbers may not add due to rounding.
Mining Plus is a mining engineering consultancy, established in 2006, consisting of skilled experts specializing in mining engineering, geoscience, and mining operation management. The resource estimate is based on the results from diamond drilling up to and including drill hole SA-16-059 for a total of 7,432 metres. The “Effective Date” for the Inferred Resource Estimate is October 25, 2016.
Two discrete domain types were modelled; D1 – disseminated silver mineralization in a horizontal rhyolite crystal tuff, and D2 – disseminated and stockwork veinlet hosted silver mineralization crosscutting the horizontal tuff horizon. D1 is of average grade material and includes a top capping of values at 225 g/t Ag. D2 is of higher grade material and includes a top capping of values at 1,500 g/t Ag.
The block model was run at different block sizes of 5x5x3 metres and at 20x20x3 metres. Sub-blocking was used to model the D2 high grade domain. Grades were assigned to the blocks by the Ordinary Kriging (OK) method, which correlated well with the Inverse Distance Squared (ID2) method. Bulk Density values were assigned by the ID2 method.
The following graph illustrates the “Grade – Tonnage Curves.” The large block size 20x20x3 metres and the small block size 5x5x3 metres are nearly identical.
A detailed, National Instrument 43-101-compliant “Technical Report” on the Boleras Silver Deposit's resource estimate will be filed on SEDAR within the next 45 days.
Silver mineralization is hosted in a rhyolite volcanic dome. An altered and highly permeable crystal lithic tuff unit contains disseminations of silver bearing minerals and domains with broadly spaced stockwork veinlets. The current working model has a porphyritic rhyolite unit, with andesite sills, as an impermeable cap, which may have focused mineralizing fluids into the host permeable volcanoclastic unit.
The drill programs were managed by Orex which maintains a QA/QC sampling protocol for the diamond drilling program, including the insertion of commercial analytical standards and blank samples. Analytical testing was performed by Bureau Veritas. Silver was determined by fire assay with a gravimetric finish. Multi-element analyses are also determined using a 4-acid digestion and ICP-MS (Inductively Coupled Plasma Mass Spectrometry).

Sandra-Escobar Silver-Gold Project, Durango, Mexico:
The Sandra-Escobar project is located 200 km northwest of the City of Durango, Mexico, in the heart of the “Mexican Silver Trend”, with excellent access and infrastructure. This prolific trend hosts some of the world’s largest silver camps and deposits with many past and present producing mines and significant silver-gold deposits. The Sandra-Escobar project area covers over 6,333 hectares of mineral concessions with multiple mineralized epithermal veins and breccia structures. These veins and structures form a high level silver-gold-base metals system, hosted in andesitic and rhyolitic rocks, and are centered on a large rhyolite dome complex in the north with silver-dominant systems around smaller rhyolite dome complexes to the southeast. Under the terms of the agreement dated September 15, 2015, Orex has an option to earn up to 65% interest in the project through total cash and share payments of $1,000,000 and exploration expenditures of US$4,000,000 over five years.
