First Tin PLC announced an updated Mineral Resource Estimate ("MRE") for its 100% owned Taronga Tin Project in Australia, completed by independent geological consultants H&S Consultants Pty Ltd. ("H&SC"). The MRE has been prepared in accordance with the 2012 JORC Code & Guidelines. The updated MRE is reported using a 0.05% tin ("Sn") cut-off to a maximum depth of 300m below surface (650mRL): This is a substantial 240% increase in size on the previous MRE announced by Aus Tin Mining Ltd. in 2014 which was calculated using a 0.10% Sn cut-off.

The lower cut-off for the updated Mineral Resource is based on revised economic considerations including higher 3-year trailing tin prices, lower AUD:USD exchange rates and preliminary estimates of mining, processing and G&A costs. The comparison represents a 40% increase in total contained tin metal based on the same cut-off. The difference is primarily due to: Exploration drilling by First Tin successfully extending the Mineral Resource to the southwest of the existing estimate; A new geological interpretation; and A reconfigured grade interpolation technique.

A Measured Resource category has been included for the first time. This is based on the successful hole twinning drill programme conducted by First Tin which validated the Newmont drilling data alongside a more in-depth study of the Newmont QAQC data which confirmed the reliability of the historic drilling data.
