The Acacia property is located on the southern side of Sinmax Creek, approximately 22 kilometres south east of Barrier.
The area is underlain by the Devonian or older part of the Eagle Bay Formation rocks consisting of phyllite, sericitic quartzite and quartz biotite schist. The area is dominated by a series of northwest trending, shallow dipping, tight overturned folds, with penetrative axial planar cleavage defined by lower to middle greenschist metamorphic minerals. These folds are west-verging, have parallel axial traces to, and are likely related to a series of southwest-directed thrust faults.
Locally, the area is underlain by metavolcanics and metasediments of the Homestake and Acacia Assemblages. Structurally, the area is a moderately dipping homoclinal sequence characterized with an average 300°strike and 25 to 40° north east dip. Foliation parallels bedding contacts with an average strike and dip of 116/40° north east. This parallel relationship implies isoclinal folding. Minor folds with moderate wavelengths mapped at several localities all have minor fold axes with consistent east-northeast plunges of 30° to 40°.
Mineralization at the showing is believed to be the strike extension of the package that hosts the volcanogenic massive sulphide Rea Gold deposit (082M 191) located 6.5 kilometres to the north.
Locally, eight mineralized zones occur in the calcareous mafic metavolcanics as stratiform massive sulphides of, primarily, pyrite, or remobilized sulphides of galena and sphalerite in epigenetic veins.
In 1987, Esso Minerals Ltd. came across the centrally positioned historic Acacia area showings on the south side of Sinmax Creek within the Acacia and Delores Creek tributaries. These showings consist of at least eight massive sulphide and vein occurrences within the Eagle Bay Formation felsic volcanics, mafic volcanics and calcareous schists. The following year Esso Minerals conducted grid soil sampling, 1:2500 scale mapping and ground VLF geophysical surveying.
In 2000, Eagle Plains Resources acquired 4800 hectares of claims in the area of the Acacia showing. Eagle Plains completed an initial survey of the property in 2000.
In 2007, a small exploration program of prospecting, geological mapping, soil geochemical sampling and diamond drill preparation was completed.
In 2008, a 738 line-kilometre airborne geophysics survey program, consisting of both magnetic and radiometric aspects, covered the entire property.
In 2010, exploration consisted of a soil sampling program to follow up on several of the anomalies that were identified by the 2008 airborne geophysics program.
In 2011, Eagle Plains Resources Ltd. optioned the property to Ecomax Energy Services Ltd., who changed their name to Tasca Resources Ltd. later that year.
In 2012, Tasca Resources Ltd. completed 616 metres of diamond drilling in six holes in the Acacia zone. Highlights include a 2.75 metre section from drillhole AC12001, which graded 1.96 per cent lead, 0.52 per cent zinc and 18 grams per tonne silver (Press Release, Tasca Resources Ltd., August 24, 2012).
Tasca Resources Ltd. dropped their option in June 2013.
