NDMC has four early stage mineral properties within the Archean Uchi Greenstone Belt, centred approximately 90km east of Red Lake. The claim groups from north to south are: Shabu (gold), Dent-Jackson (gold and base metal); Maskooch (gold and base metal) and Ear Falls (gold). Cross River will continue with desktop compilations of each of these blocks followed by ground truthing of key outcrops in 2021 designed to generate diamond drill targets.
The Shabu Lake claim block covers a narrow wedge of greenstone located along the northwest margin of the Uchi Belt. The Ontario Mineral Database has four mineral occurrences on the claim block with exploration work ranging from the late 1930’s to 1980’s. The most significant occurrence is called Shabu (MDI 52N07SW 0002) and consists of a narrow (10-15cm wide) quartz vein cross cutting weakly altered gabbro and diorite. A total of 6 drill holes were completed and each intersected a pyrite and chalcopyrite bearing (up to 2% copper) zone with hematite and epidote alteration. The best intersection was 1.065 ounce/ton gold over 15cm. Despite the narrow nature of this zone, the high-grade values warrant a detailed evaluation and follow-up. The Cross River technical team intends to undertake a structural desktop study of the claim block to aid with target generation.
The Maskooch claim block occurs along the southeastern margin of the Uchi Belt, approximately 100km east of Red Lake. The claims are underlain by a series of mafic to felsic volcanic rocks with narrow intervals of banded iron formation. Previous exploration has identified extensive alteration suggesting high potential for base metal sulphide mineralization (VMS) as well as lode gold deposits. Two historical mineral occurrences are known on the property: Maskooch (copper) and Wenesaga (gold). The Maskooch copper occurrence has reported trench samples of 0.43% Cu over 1m from sampling completed in 1984 (MDI 52K16NW 00014). Subsequent diamond. drilling of airborne electromagnetic conductors in 2009 yielded weakly anomalous copper and gold from sulphidic iron formation. The Wenesaga Road gold prospect was trenched in the late 1980’s in order to follow up reports of high-grade surface gold, however no assays are available (MDI 52K16NW 00006). A single drill hole is reported in the area from 1990 that yielded weakly anomalous gold values.

The Dent-Jackson claims occur in the west central portion of the Uchi Belt, approximately 25km south of the Shabu claims and 25km north of the Maskooch claims. The property is underlain by similar volcanic stratigraphy as nearby past-producing gold and base metal mines, including the South Bay Cu-Zn-Ag Mine located approximately 6km east of the claim block. Ongoing interpretation of previous work reports by the Cross River technical team is expected to result in a geological framework of the entire area which will be used to evaluate opportunities for further work.
The Ear Falls claim block is located southwest of the Uchi Belt and occurs within an Archean clastic metasedimentary belt approximately 15km west of the community of Ear Falls, Ontario. This region does not have any recorded history of gold exploration; however the Cross River technical team believes this geological setting has been overlooked by previous workers and the company intends to complete a detailed structural study in hopes of focusing and prioritizing ground work for 2021.
