Access Description: Access is either from the west via a gravel road that departs from Hwy 655 and traverses southern Prosser Twp., or from the east via bush trails that depart from the gravel road passing by Ice Chest Lake.
The following text is quoted from a report by H.A. Pearson in assessment file T-2637: Originally the group was staked as a base metal prospect: but, subsequently, diamond drilling of the electromagnetic conductors outlined three gold deposits: the Texmont and Frankfield zones on the Intex property and a similar deposit on the Nickel Offsets property which adjoins to the south. Diamond drilling what appeared to be the faulted extension of the Texmont Zone conductor, during 1974-5-6, Intex and Frankfield outlined the Frankfield Zone, 4,000 feet east of the Texmont Zone. Along a 600-foot length, the Frankfield Zone averaged 0.23 oz/ton Au over an average core width of 15.5 feet. Diamond drilling was completed in 1981 and 1988. 1991: Cyprus Gold (Canada) Ltd. - 7 ddh (3638 m), ground geophysics, 2003-14: Gowest Amalgamated Resources Ltd. /Gowest Gold Ltd. - airborne geophysics, soil survey, mapping, metallurgical testing, DD-273-79,606 m

Aug 21, 2015 (A Wilson) - The deposit is hosted by mafic to intermediate flows with minor, narrow interflow ash tuff and carbonaceous-graphitic sedimentary horizons. Ultramafic flows occur as occasional, narrow units in the lower portion of the sequence and as a thick basal unit. The stratigraphy strikes east-west, with a dip of 75-85 to the north. Mineralization in the Main Zone occurs within a fractured and brecciated altered horizon interpreted as a shear zone in hanging wall basaltic flow rocks at or near the contact with steeply north-dipping footwall ultramafic rocks to the south.

Aug 21, 2015 (A Wilson) - Diamond drilling by Cyprus returned values of 4.55 g/t Au over 5 m, 4.77 g/t Au over 6.05 m and 6.35 g/t Au over 2 m. The mineralization is interpreted as a massive/tabular structure that is consistently present throughout the mineralized horizon. Within the Main Zone, higher-grade gold mineralization is localized along the footwall of the Shear (MZ1 Zone) and occasionally along the hanging wall of the shear zone (MZ2 Zone). Sporadic, anomalous to lower grade gold mineralization is present between these two subzones. The Bradshaw Deposit comprises a geological Main Zone and several lesser Hanging Wall Zones. Gold mineralization in the Main Zone occurs primarily within a fractured and brecciated altered horizon, previously interpreted as a shear zone in hanging wall basaltic flow rocks at or near the contact with steeply north-dipping footwall ultramafic rocks to the south. The mineralization is not confined to narrow, vein-like structures, but in a more massive/tabular structure that is consistently present throughout the mineralized horizon. Within the geological Main Zone, higher-grade gold mineralization is localized along the footwall of the horizon (MZ1 Zone) and occasionally along the hanging wall of the horizon (M22 Zone). Both gold mineralized zones appear to rake steeply to the east based on current drill data. Their variation in widths may reflect tectonically controlled shoots or boudinage structures.
Dec 07, 2005 (R Pressacco) - Pearson (Assessment file T-2637) states that pyrite abundance is 3-10% and that arsenopyrite abundance is less than 1%.

Date: Jun 01, 1999
Geologist: R Pressacco
Notes: The existing resources are calculated to a vertical depth of 250 feet (75 metres), and the zone has an average width of 10 feet. Two deeper drill holes intersected good values. DDH 88FI-11 intersected a weighted average grade of 0.254 oz./ton Au along a core length of 14.9 feet (8.71 g/t Au / 4.54 metres) at a vertical depth of -1000 feet. DDH 88FI-12 intersected a weighted average grade of 0.092 oz./ton Au along a core length of 52.2 feet (3.15 g/t Au / 15.91 metres) at a vertical depth of 650 feet. Aside from these two holes, no significant drilling has been done below -250 feet.
Date: Jun 25, 2004
Geologist: A Wilson
Notes: The strike length of the deposit decreases with depth, along a steep westerly plunge to a length of about 200 m at a vertical depth of 300 m. The deepest intersection (2.37 g/t Au over 3 m) was encountered in hole T-91-6 at 600 vertical metres. The gold mineralization is irregular and somewhat discontinuous in nature. The style of the mineralization suggests that the vein zones may be concentrated in discrete pods and shoots angled away from the main trend of the zone.
