Cross River Ventures Corp. (CSE: CRVC) (FWB: C6R) (the "Company") is pleased to announce ongoing data compilation at the Dent-Jackson project, located in the Birch-Uchi greenstone belt, northwestern Ontario, has revealed previously overlooked zones of high grade gold mineralization that remain untested by prior operators.
The property's gold endowment attracted attention as far back as 1927, when the Jackson-Manion Consolidated Mines discovered gold along the eastern margin of the claim block which they mined from 1934 to 1940. The mine produced approximately 27,146 ounces of gold and 18,300 ounces of silver at an average grade of 0.258 ounce/ton Au during several years of operation (Parker & Atkinson, 1992). The focus of the mine was gold in quartz veins associated with mafic volcanic rocks. In the 80 years since, the project was explored sporadically, and mineral title changed hands several times. Most of the later work focused on the area around the historic Jackson-Manion mine. However, there are three other gold occurrences on the Dent-Jackson property that remain underexplored.
TheCross River Ventures technical team has identified historic data which documents high-grade trench samples from the Cariboo Vein in the western part of the property, and the East of Little Woman Lake Zone in the central part of the property. Historic diamond drill programs on the property (incl. Ontario Woman Lake Gold Mines Ltd, 1929; South Bay Mines, 1970; Condor Precious Metals, 2012) did not adequately test these target areas.

"The Cross River technical team's detailed data compilation and review is a critical step in the systematic exploration approach we're pursuing in Ontario," said CEO, Alex Klenman. "These findings highlight important facts about the geology and potential gold endowments within the claim blocks and provide essential guidance for targeting in the months ahead. The exploration strategy is to advance all of the company projects to drill-ready status, using a data driven approach that results in optimal target generation. When we drill, we want to be sure we're putting those holes down in the best possible places for meaningful discovery," continued Mr. Klenman.
Cariboo Vein
In 2002, Fronteer Development Group sampled historic trenches along the northwest striking Cariboo quartz vein, that yielded values ranging from nil up to 232.9 grams-per-tonne ("g/t") gold ("Au"), and in excess of 33 g/t silver ("Ag"). The sampling consisted of channel samples spaced at 1-meter intervals along the length of the exposed vein. An 8-meter long section of trench 2 averaged 26.8 g/t Au over an average width of 53.6 centimeters. (Fronteer, 2002: AFRI 52N02NW2001).
Significant results are detailed in Table 1, below:

The Cariboo Vein is a historical outcrop of 10 cm - 80 cm wide quartz vein at surface with chalcopyrite, pyrite, and visible gold. Historically, it was exposed in three trenches over 140 meters (Fronteer, 2002: AFRI 52N02NW2001). The vein is open along strike as it trends under cover to the west and runs into a lake towards the east. Historical drilling targeted electromagnetic (EM) anomalies and did not accurately evaluate the veining. Cross River field crews will assess this target in Q2/Q3 2021 and determine how to best evaluate and trace this vein system.
East of Little Woman Lake Zone
Historic exploration at this location is said to date back 80 years and consisted of trenching, pitting and shaft sinking (Guilin, 2013), however little historic data exists. Most recently, Guilin Kingsland Mining Co sampled material at this location in 2013 resulting in numerous high-grade surface samples up to 68.0 g/t Au (Table 2) across a 570m east-west strike length. No follow-up work is documented on this high-grade target area, and no historic drilling is known in the vicinity.

The samples were collected at an intrusive volcanic contact and historic reporting suggests that the mineralization has skarn-like affinities. Follow-up work is being planned to locate additional high-grade quartz stockwork and veins using mapping, geochemistry, and geophysics.
Conclusions
The initial data review of publicly available assessment reports for Dent-Jackson revealed the presence several high-grade shear hosted gold occurrences with limited testing and exploration work performed by previous operators. Ongoing geological interpretations of the claim block will focus on interpreting the regional structural framework which will allow for a predictive model of shear zone geometry in plan and 3D. Acquisition of LIDAR data in Q2 will aid in the structural reconstruction and provide a baseline tool for field crews to use during the Summer 2021 ground assessment of the claim block. The Company is hoping to generate quality drill targets for testing later in 2021.
The Cross River technical team is currently completing data reviews on all of its projects in NW Ontario and expects to complete the reviews prior to Q2 2021.
