Location Method: Based on Assessment

Access Description: From Shabaqua on Hwy17 travel 1 km south on the Shabaqua Road to Shabaqua Corners Road. Travel 2.9 km to the end of Shabaqua Corners Road crossing the CN rail line. Turn west onto Haner Road and travel 2.1 km. Turn north onto a secondary haulage road and travel 1.3 km to the Wedge Zone just north of a creek. Continue to km 2.5 to access the area of drilling for the Creek Zone. The Creek Zone is under the creek.

Exploration History

1980s: Noranda is thought to have dug trenches investigation geophysical anomalies for base metals. 1984: Corporate Oil & Gas Ltd. carried out mapping and sampling. 1991: Ontario Geological Survey released an Aerodat regional airborne magnetic and electromagnetic survey over most of the Shebandowan belt. The results of this survey were re-compiled by Burt Consulting Services on behalf of RJK and used to generate a series of magnetic and electromagnetic anomaly maps. 2003: RJK/Hinterland Metals completed 10 diamond core holes for 1,773 metres over two phases of drilling. Phase 1 totalled 964 m and drill discovered the Creek showing. Phase 2 drilling totalled 809 m and drilled the Wedge and South zones. 2005: RJK/Hinterland contracted Geotech to fly a 483 line-Km VTEM/Mag survey over the Wedge property. 2012: The RJK/Hinterland claims lapsed. 2017: D. Parker carried out sampling. 2019: Delta Resources optioned the property. 2020: Delta Resources carried out a till sampling program,

Geology Comments

Sep 23, 2016 (Andrew Tims) - There are relatively few outcrops on the Wedge claim block, and most of those are on the northern Kashabowie Formation on either side of the Kaspar gold showing. Almost all of the mineralization hosting units of the Greenwater Formation are locally covered by up to 20 metres of overburden. Most of the information on the geology in the immediate area comes from observations on the recent diamond drill core.

Lithology

Mineralization

Mineralization Comments

Sep 23, 2016 (Andrew Tims) - Zone is composed of 5-7% quartz stringers and veins with up to 3% pyrite and arsenopyrite in altered volcanics and graphitic mudstone. The zone returned 342 ppb gold over 10.75 metres (about 9 metres true width), including 4.0 metres of 725 ppb gold and 1.0 metre of 1,300 ppb gold.

May 26, 2023 (Therese Pettigrew) - At the South Zone, 2 units of graphitic argillite are present in a package of mafic flow units exposed in a series of previously stripped trenches. The volcanic rocks are commonly brecciated, fractured and altered with ankerite, calcite, quartz stringers, an unidentified black mineral on fractures and sulphides. The southernmost argillite is poorly exposed in a series of stripped areas between the trenches. The northern most graphitic argillite is exposed in one trench. 8 rock samples were taken at the South Zone trenches. Most of the samples returned anomalous arsenic up to 446 ppm and many of the samples were anomalous in gold with the highest value of 1430 ppb being returned from altered volcanic in the area of the northern ­most argillite horizon (Assessment report 20000015104).

Geologist: Mark Puumala

Notes: Two historical trenches were examined in the South Zone area. These trenches expose a sequence of mafic to ultramafic metavolcanic rocks that are intercalated with horizons of graphitic mudstone. Foliation strikes approximately 125° with near-vertical dip. Grab samples were collected from sulphide mineralized (pyrite + arsenopyrite) and iron carbonate-altered rocks that were observed in each trench at approximately the same stratigraphic level. One of these samples (MP17WPT112) returned an assay of 107 ppb Au. A third sample (MP17WPT111) collected from a quartz vein crosscutting graphitic mudstone returned an assay of 26.7 ppb Au (Puumala et al., 2018).
