Exploration History

1934: Birch Bay Gold Mines conducted surface trenching and diamond drilling on north half of Lots 68 and 69, Concession A. Noranda Mines investigated mining claims adjacent to the Birch Bay property. Mattawin Gold Mines Limited later restaked the unpatented lots. 1936: Preeport Exploration Company conducted diamond drilling and trenching. 1947: W. D. Neel wrote report on Mattawin Gold Mines Limited property. 1948: M. W. Bartley, (consultant) examined the property for Mattawin Gold Mines Limited. 1950: T. W. Page, (consultant) examined the Mattawin Gold Mines Limited property. 1966: Cliffs of Canada initiated a self potential survey on a section of the area (claims TB252672 and TB263159). 1970: Noranda Mines Limited carried out geological mapping and geophysical surveys, on claims TB252672 to TB252677 and TB263158 to TB263159. 1972: Getty Mines Limited conducted geological mapping, Very-Low-Frequency - Electromagnetic ground geophysics, soil and rock geochemistry on 39 mining claims and Lots 67 and 69. Exploration for base metals, concluded by one diamond drill hole. 1980: Lynx-Canada Explorations Limited completed 5 diamond (Mattawin Main Zone) drill holes (346 metres), assay results were discouraging. 1996: Freewest Resources and Greater Lenora Resources optioned the property. 1997: Freewest Resources and Greater Lenora Resources completed conducted mechanical stripping, soil geochemical surveys, magnetometer and induced polarization surveys, sampling, detailed mapping followed by 3-hole drill holes testing the depth extension of mineralization. Prospecting uncovered a new showing situated 130 metres away from the Bylund occurrence with assays up to 2.81 g/t Au. 1999: Freewest Resources and Greater Lenora Resources completed a two-hole drill hole program. 2022: Delta Resources entered into a 5 year lease agreement with the surface and mining rights landowners. 2024: Delta Resources Ltd. completed 4 diamond drill holes totaling 1,371 m.

Geology Comments

Jun 06, 2023 (Therese Pettigrew) - The property is located in the north-central portion of the Shebandowan greenstone belt. The metavolcanic rock-dominated Shebandowan greenstone belt is located within the Wawa Subprovince, and is bounded to the north by the metasedimentary rock-dominated Quetico Subprovince. Both of these subprovinces are Neoarchean in age, and their boundary is defined by the Postans fault in the Shabaqua area (Corfu and Stott 1998). Two distinct supracrustal rock suites known as the Greenwater and Shebandowan assemblages have been identified in the Shabaqua area (Lodge et al. 2015; Lodge and Chartrand 2013; Corfu and Stott 1998). The Greenwater assemblage is older (ca. 2720 Ma), and is dominated by mafic to felsic metavolcanic rock cycles consisting of tholeiitic to calc-alkalic rocks, along with some komatiitic rocks (Williams et al. 1991). The younger (<2690 Ma) Shebandowan assemblage unconformably overlies the Greenwater assemblage and is dominated by clastic metasedimentary rocks, with subordinate calc-alkalic to alkalic intermediate metavolcanic rocks and intrusions (Lodge et al. 2015). The unconformity between the Greenwater and Shebandowan assemblages has a close spatial association with numerous gold occurrences in the Shabaqua area (Schnieders et al. 2003; Puumala et al. 2017). Greenwater assemblage rocks occur to the south of highways 11 and 11-17. These rocks have been mapped largely as mafic to intermediate metavolcanics (including massive and pillowed flows). These metavolcanic flows are intercalated with relatively thin (<35 m) horizons of mudstone, chert, and jasper-magnetite and chert-magnetite iron formation. Numerous “lensoid” gabbro bodies intrude the Greenwater assemblage supracrustal rocks throughout this area (Carter 1985, 1987). Shebandowan assemblage rocks are found in the area along and immediately to the north of highways 11 and 11-17. This assemblage is dominated by clastic metasedimentary rocks, including conglomerate, sandstone, siltstone and mudstone. These rocks are interlayered with distinctive trachyte and trachyandesite flows that commonly display a patchy red and green appearance and tend to be amphibole-phyric. These rocks are intruded by feldspar-phyric felsic to intermediate dikes, gabbroic intrusions and lamprophyre dikes (Carter 1985, 1987). Foliation is well-developed in the supracrustal rocks of the Shabaqua area and generally strikes east-southeast with near-vertical dip. These rocks have been deformed into tight isoclinal folds with east-southeast striking axial planes (Carter 1987). Shear zones that parallel the regional foliation occur throughout the area and are especially well-developed along trends that coincide with the gold-mineralized zones on the Shabaqua Project properties. Osmani and Rees (1997) suggest that one of these deformation zones is a major east-striking “break” that connects the Postans and Crayfish Creek faults. This structure passes through the Shabaqua West property and is known as the “Kasper” fault. Several additional northeast-trending faults that are evident as significant discontinuities on magnetic maps have been mapped and/or inferred in this area (Osmani and Rees 1997; Morgan and Rees 1997). These structures also have a close spatial association with gold mineralization.

Mineralization Comments

Sep 09, 2016 (Andrew Tims) - The stripping uncovered a broad, NNE-trending deformation zone within carbonatized and silicified Timiskaming sediments. Sampling outlined a highly anomalous zone up to 19 metres wide assaying greater than 1.0 g/t Au with individual assays returning 6.9, 14.6 and 5.6 g/t Au respectively. All 3 of the holes intersected anomalous gold values ranging from 0.1 to 0.5 g/t enveloping the higher grade sections over widths of up to 15 metres. Within this 125 m wide zone, carbonate-altered, mafic to ultramafic metavolcanic rocks are transected by a stockwork of quartz-carbonate veins. Grab samples have assayed up to 9.7 g/t Au. Hole BY-99-2 intersected a broad zone of intensely altered, deformed volcanic breccia, with moderate to intense ankeritic and sericitic alteration over 102.6 metres. The zone assays 0.32 g/t Au over 102.6 metres from a depth of 8.7 to 111.3 metres. Narrow higher grade intervals were obtained in local zone of quartz veining and heavier pyrite-arsenopyrite mineralization. Hole BY-99-1 returned insignificant gold values.

Mar 06, 2024 (Sheree Hinz) - Delta Resources Ltd. carried out a diamond drill program on their Delta-1 property to fill in gaps from their previous drilling and to potentially expand the mineral envelope. Drill hole D1-24-90 intersected 15.94 g/t Au over 10 m including 99.40 g/t Au over 0.90 m.

Geologist: Therese Pettigrew

Notes: RGP staff visited the property on May 30, 2023. The original area stripped by Freewest was located. The stripped area is approximately 60 m long by 57 m wide. The mafic metavolcanics (unweathered medium grey) have been strongly altered and are weathering reddish brown. There are thick interbedded intervals of chert with disseminated to massive sulphides (pyrite, arsenopyrite, chalcopyrite) alternating with less altered grey metavolcanics. Spinifex textures were observed in highly silicified metavolcanics on the far northeast side of the cleared area. Quartz-carbonate veins crosscut the other lithologies in a NE-SW direction.
