The Mozart and nearby Beethoven showings are situated north of Bradshaw Creek, 9 kilometres northwest of Olalla and 6 kilometres east of the Similkameen River.
The regional geology of the area consists of a series of Carboniferous to Triassic volcanic and sedimentary rocks that have been intruded by granitic Okanagan intrusions. Larger intrusions are composed of granite and granodiorite, whereas smaller stocks are composed of diorite and gabbro. Numerous sills, dikes and apophyses are associated. Carboniferous to Triassic rocks are assigned to the Shoemaker and Old Tom formations, overlain by the Upper Triassic Independence Formation. These rocks form the eastern limb of a large anticlinal fold with fold axes striking roughly north.
The predominant rock type in the claim area is a dark brown, grey to white, fine-grained, massive competent chert. Occasional thin beds up to 0.3 metre thick are identified by layers of chert pebble tuff or silt. The age of these chert beds is uncertain and could belong to the Independence or Shoemaker formations. The cherts are in fault contact with andesitic volcanic rocks called the Old Tom Formation. Jurassic diorite and gabbro intrusions cut the cherts and andesites. A pervasive quartz-calcite alteration affects the andesitic rocks and the diorite intrusion. The four main rock types encountered at the occurrence are argillaceous chert, dark green andesite, buff chert and chert breccia, and biotite hornblende diorite. A number of narrow, north-trending, postmineral andesite dikes are also present.
The Mozart and Beethoven occurrences were discovered in May 2004 and consist of chert-hosted arsenopyrite veining north and northwest of a hornblende diorite stock. Both occur in small shear zones within weakly pyritized, silicified and argillically altered chert.
The Mozart zone is up to 15 metres wide with abundant fine arsenopyrite veining and centred on a 7-centimetre-wide massive arsenopyrite vein. Assays from this vein returned 6.35 grams per tonne gold over 0.07 metre. Anomalous samples from the rest of the zone range from 0.177 to 1.67 grams per tonne gold (Assessment Report 27746).
The Beethoven zone is approximately 6 metres wide and consists of fine arsenopyrite stringers, with gold values ranging from 0.018 to 0.024 gram per tonne gold. A sample from a nearby adit returned 0.383 gram per tonne gold over 1.5 metres (Assessment Report 27746).
The present Bradshaw Hill property was expanded by C. Greig, partner to B. Kreft, in January 2004, just prior to the finalization of an option agreement with Firestone Ventures Inc. In the same year, a work program carried out by Firestone Ventures Inc. consisted of five days of helicopter-supported detailed geological mapping, rock geochemical and limited silt and soil geochemical sampling. The program focused on due diligence–style sampling of the Main zone (MINFILE 082ESE180) and “ground truthing” of geochemical anomalies to the east and west.
In 2005, Target Exploration and Mining Company optioned the property. Target undertook geological, geochemical and geophysical work between 2006 and 2008. In 2007, Target completed a total field magnetics and induced polarization survey, approximately 3.5 by 0.8 kilometre in size, following the east-northeast trend of mineral showings on the property. Sampling resulted in zones of anomalous metal values in soil coincident with chargeability and resistivity anomalies.
Soil sampling between 2007 and 2012 has outlined multi-element geochemical anomalies near known mineralization.
