Silver and gold mineralization at Martha is hosted in Jurassic-aged felsic volcanic rocks of the Chon Aike Formation of the Bahia Laura volcanic complex (BLVC). Host rocks are relatively shallowly dipping ignimbrites, locally inter-bedded with thin sections of sedimentary strata.

The oldest geological unit in the Martha area is a crystal rich, dacitic ignimbrite, which is overlain by a thin, tuffaceous unit. Further up in the Chon Aike sequence rocks change to crystal rich, rhyolitic ignimbrite followed again by a thin layer of tuffaceous sediments. The upper part of the sequence at Martha is comprised of lithic rich, rhyodacitic ignimbrite related to a caldera-forming, volcanic event.

Most of the historic mineral deposits were hosted in the crystal rich ignimbrites and tuffaceous units although, locally, upper lithic fragment tuffs and ignimbrites can host high-grades of vein-hosted silver and gold. An example of the latter is the mineralization in the Betty deposit at Martha.

Martha mineralization is epithermal, intermediate sulfidation in style, hosted in quartz veins, veinlets and vein breccias cutting the margins of the Jurassic-aged caldera. Vein widths vary significantly on surface from a few centimeters up to several meters. Banded textures are common in the wider veins. Adularia is a common gangue mineral in the quartz veins.

There are no mining activities underway at Martha at this time. Prior mining methods used were a combination of small surface pits and slot cuts and underground mining.

Underground mining methods consisted of drifting and shrinkage and long-hole stoping. Hunt is planning to evaluate opportunities for new mining involving a combination of similar surface and underground methods.

There are no metal recovery operations underway at Martha at the present time. The property contains a dormant crushing, grinding and flotation plant – nominally rated at 480 tonnes per day (tpd) – which is being cleaned and repaired as necessary to potential future operations.

Since Hunt is considering evaluating areas within the historic Martha mine area, which provided most of the feed to the Martha mill, the Qualified Person believes there is reasonable expectation of satisfactory metallurgical performance from the new material to be evaluated.
