Vancouver, British Columbia--(Newsfile Corp. - November 4, 2021) - Cross River Ventures Corp. (CSE: CRVC) (OTCQB: CSRVF) (FSE: C6R) (the "Company") is pleased to update shareholders on the results of recently completed exploration work at its 1,480-ha Maskootch project, situated along the southeastern margin of Archean Uchi Greenstone Belt, NW Ontario, Canada.
A team of four personnel contracted by Bayside Geoscience of Thunder Bay, Ontario, recently completed an 8-day field program at Maskootch. The team conducted prospecting and mapping around areas of historic gold ("Au") mineralization at the Wenesaga Road prospect on the western side of the project and the Maskootch copper showing on the eastern side of the project (Figure 1).
Wenesaga Road Showing
The team collected three grab samples from semi-massive pyrite-chalcopyrite mineralization at the historic Wenesaga Road showing. Two locally derived angular boulders, samples D579821 and D579823, returned values of 32.0 grams-per-tonne ("g/t") Au with 0.79% Copper and 22.5g/t Au respectively.
Sample D579822 from the mineralized outcrop returned 8.29 g/t Au and 0.31% copper. Mineralization at the Wenesaga Road showing is confined to a 30 cm wide zone of sulfide mineralization that appears to be strongly lineated, plunging 240 degrees at an inclination of 62 degrees.
There does not appear to be any significant strike extent to the showing, though it may be largely removed in the road cut. Follow up work on this zone will focus on the down-plunge extent of the mineralization.
Maskootch Copper Showing
Mapping and sampling at the Maskootch copper showing along the eastern margin of the property returned 3 samples with elevated copper values. The team collected the samples from a series of historic trenches along a contact between felsic-intermediate tuff breccias and tuffs and mafic tuff breccia to iron formation. Samples D579784, D579791, and D579796 returned 0.30%, 0.09% and 0.06% copper, respectively.
Gossans host the mineralization along this contact zone. They reflect the presence of iron oxides and sulfides in the host felsic-intermediate volcaniclastics. The mafic volcanic rocks nearby contain garnet porphyroblasts and magnetite-pyrite mineralization. These minerals indicate extensive hydrothermal alteration.
The team mapped this E-W trending horizon nearly continuously over 3 km south of Maskooch Lake. An intermediate volcanic breccia sequence, just south of the contact, shows strong bleaching and chlorite alteration cutting bleached host rocks.
A cursory model of this area indicates that the bleached and chloritized intermediate volcanic rocks to the south of the sulfide bearing horizon may be the footwall alteration system to potential VMS style mineralization.
On the west side of Maskooch Lake a ridge of intermediate volcanic tuff, sample D579811, returned 0.15% Copper. This area in general has minimal outcrop exposure due to the presence of sandy till in the area. Mineralization and mineralogy here is like that on the east side of Maskooch Lake, suggesting continuity of this strata 3km to the NW
In addition to confirming high grades in the central part of the property adjacent to Wenesaga Road, the team identified a new gold showing in the northeastern portion of the property called the Skootch Showing.
The team collected a total of 87 grab/outcrop/subcrop samples during the program. Four samples returned values of greater than 1 g/t Au and four samples returned copper grades above 0.10%. The Table below summarizes the selected results:
|Sample ID||Sample Method||Gold (g/t)||Silver (g/t)||Copper (%)|

Work completed during the 8-day prospecting program verified the presence of high-grade gold and elevated copper values within sulfide bearing volcaniclastic rocks. Mapping of the property suggests the presence of a hydrothermal alteration system with the potential to host gold rich VMS style mineralization down-plunge from known mineralization.
Sandy till obscures bedrock in the area north and west of Maskooch Lake. However, the anomalous copper mineralization encountered on the west side of Maskooch Lake warrant geophysics in the future.
The Maskootch project is a 1,480-hectare claim block on the southeastern margin of the Uchi Greenstone Belt. A series of ultramafic to felsic volcanic rocks underly the property. The volcanics contain narrow banded iron formation intruded by foliated tonalite.
Previous work was focused on Volcanogenic massive sulphide mineralization based on mineralization textures associated with gold and copper showings including Maskootch (copper) and Wenesaga Road (gold). (Figures 1 and 2).
The Maskootch copper prospect sits near the contact between tonalite intrusions and intermediate to felsic metavolcanics. Trench samples reported in 1984 include 0.43% Copper over 1m. Grab samples reported in 1986 returned anomalous but low-grade gold (MDI 52K16NW 000141). In 2009, diamond drilling of airborne electromagnetic conductors returned weakly anomalous copper and gold values from sulphide-bearing iron formation.
The Wenesaga Road gold prospect is situated in felsic-intermediate metavolcanic rocks along the western side of the Maskootch property (Figure 1). There are anecdotal reports of high-grade surface gold (several oz Au samples referenced in the 1991 MDI**. There are no assays available from trench sampling in the late 1980's. There is a single drill hole reported in the area from 1990 that yielded weakly anomalous gold values.
The Maskootch property is considered underexplored despite its favourable host rock geology, extensive alteration footprints which indicate the land position has potential for economic orogenic gold and/or VMS style mineralization. High-priority exploration targets include mafic-felsic rock contacts, margins of mafic-ultramafic intrusions, and iron formation host rocks; all of which have yielded significant deposits in the region.
The Maskootch property is an overlooked exploration asset in the Uchi Greenstone Belt. The recent option agreement between Kenorland Minerals and Barrick Gold Corp. on ground surrounding Maskootch demonstrates the renewed interest in the region. Barrick Gold agreed to spend $6 million over six years to earn 70% of the South Uchi project.

All 2021 samples pertaining to this release were sent to ALS Geochemistry Laboratories in Thunder Bay, Ontario, for analysis. Samples were prepared using PREP-31 standard rock/core package and analyzed for gold using standard Fire Assay and ICP-AES (ALS Code: Au-ICP21). Samples returning over 10.0 g/t Au were then analyzed using Fire Assay - Gravimetric finish methods (ALS Code: Au-GRA21).
* Note: Grab samples are selective by nature and may not be representative of the average grade or style of mineralization but will be used to help guide additional exploration on the properties.
