Telson Mining Corporation

We at Telson believe we have a mission to create enduring, sustainable value for all our shareholders, employees and the communities where we work.

The mineral resource has been limited to mineralized material that occurs within the mineralized blocks and which could be scheduled to be processed based on the defined cut-off grade. All other material was reported as non-mineralized material.

Tahuehueto Project Mineral Reserve Estimate
Classification Tonnes (x 1000) g Au/t Oz Au (x 1000) g Ag/t Oz. Ag (x 1000) Cu% Lbs. Cu (x 1000) Pb% Lbs. Pb (x 1000) Zn% Lbs. Zn (x 1000)
Probable Reserves 3,264 3.40 356 41.80 4,387 0.35 25,028 1.19 85,762 2.24 161,314

Note: Mineral Reserves were defined as mineralized material that occurred within the stope shapes that were based on and NSR value of $62/t. Measured and Indicated resources within the defined mining shapes (stopes) were used to estimate Probable Reserves. No Proven Reserves were defined due to the limited definition resource drilling, limited definition by exploratory mining and the lack of geotechnical data that addresses underground mining. Probable Mineral Reserves include the effects of mining dilution assumptions which average 15% and extraction ratio assumptions which averaged 94%. Mining dilution was assumed to have zero (0) grade.

Canadian Institute of Mining, Metallurgy and Petroleum standards were followed in the estimation of the Mineral Reserves. Mineral Reserves were estimated using metal price forecasts of $0.60/lb for lead, $0.75/lb for zinc, $2.10/lb for copper, $1,000/oz for gold and $19.12/oz for silver. The low metal prices were selected to drive the mine plan towards mineralization with the highest confidence in the prospects of economic extraction. These metal prices were not used for the economic analysis of the mineral deposit. Totals may not add due to rounding. The foregoing mineral reserves are included within the current Mineral Resource Estimate for the Project.

Note: The above mineral resources have been calculated using a cut-off of 2.5 g/t Au Equivalent. These resource numbers are preliminary in nature. They include inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves.
