Summary:

Mineralization at Joaquin is classified as low sulphidation hydrothermal breccia.

Silver and gold mineralization is hosted within a northwest trending structure that dips approximately 45° to the northeast. The majority of the mineralization is hosted within a silicified breccia, with lesser stockworks and veinlets. Silver is present as native silver, bromargyrite, and acanthite/argentite, with lesser stromeyerite, freibergite, and pyrargyrite/stephanite. The sulphide content is low and consists principally of pyrite and galena. Hematite, jarosite, and manganese oxides are commonly noted. The host minerals are dominated by quartz and feldspar. Hydrothermal alteration is weak to moderate and comprises fine grained replacement quartz and widespread illite and kaolinite alteration.

Mineralization within the economic mine plan is located between approximately 110 m and 310 m below surface and trends for 375 m along strike.
