Focus Minerals announced updated and new Mineral Resource estimations for the Patricia Jean and Jolly Briton deposits, part of the company's 100%-owned Coolgardie Gold Project. Patricia Jean and Jolly Briton are hosted in the Three Mile Sill along with other key deposits within the Coolgardie Gold Project (Coolgardie), which covers 175km2 of highly prospective tenements on the outskirts of the Coolgardie township in the Goldfields region. Focus is working towards resuming gold mining operations at Coolgardie.

Both deposits are hosted by the prolifically mineralised Three Mile Sill (TMS) mine stratigraphy. This stratigraphy hosts bulk-style mineralisation at other deposits led by Three Mile Hill, Lindsays, Greenfields, CNX and Green Light. The mineralisation at Patricia Jean and Jolly Briton is open to extension along strike and at depth.

Importantly, 160m strike between the two deposits remains untested. It is noted that there is significant underground development within the TMS south of the Jolly Briton Mineral Resource that is yet to be targeted by modern exploration. Patricia Jean and Jolly Briton are located within the north- eastern part of a larger soil gold anomaly that extends over areas of historic shafts and mine subsidence.

Both deposits are classed as Inferred status despite historic drill spacing of 20m - 25m in parts of the mineralised system. A conservative Mineral Resource classification is being used at this time in the absence of recent confirmatory hole twinning and further infill of likely high-metal content mineralised shoots. An Ordinary Kriging (OK) estimation technique was selected and variograms were modelled in Supervisor.

Each domain was estimated separately using only its own sample values. All domain boundaries were considered "hard" boundaries and no drill hole information was used by another domain in the estimation.
