In was in the Witlage area that Sumin spent the majority of the $1.8 million that it spent on the exploration of the Nassau project. The attraction is that the informal miners have exposed gold-bearing bedrock and saprolite in the Witlage drainage where samples of quartz veins collected by Sumin contained up to 49.8 ppm gold. However, there had been almost no exploration of the Nassau Plateau upstream of the Witlage, Bamboo and Bowl drainages (i.e. the plateau itself) although the plateau is the source of the alluvial gold in each area. Moreover, hand and power auger samples southeast of Witlage to the peak of the Nassau Plateau have encountered a contact of volcanic and sedimentary rocks with clear indications of a structural boundary, about which there are highly-altered gold bearing volcanic rocks on the east side of the structural zone in auger hole MNA-31 and highly altered, gold-bearing sedimentary rocks on the west side of the structural zone in auger hole MNA-12.
In spite of the abundance of gold that is being shed from the Nassau Plateau into the Bamboo, Bowl, and Witlage drainages, the fact that there has been alluvial/colluvial/saprolite mining for 100 years, the fact that there are high grades of gold encountered in rock samples and in auger samples, and the fact that the project is in fertile stratigraphy tying on to the Newmont Merian mining license, and only 15 kilometres from the Merian pit and along a structural trend of the Sabajo deposit, there has never been a gold resource defined at the Nassau project. The reasons for this are as follows: i) Porknocking/informal mining or whatever you want to call it is inefficient, nobody knows the size, grade, or recovery characteristics of the material being mined and there has been virtually no exploration by modern methods at Nassau in spite of the fact that there has been more than 100 years of gold production, and ii) even though the stratigraphy of the rocks at Nassau is permissive for gold deposits, there has never been any diamond drilling at the Nassau project.
However, Sumin determined that gold has been reported in rock and auger samples over 5 kilometres at the Nassau project and the total inferred strike length of the gold-bearing structural corridor on the property is approximately 20 kilometres.
In 2017, 79North acquired the Nassau Project by merging with Sumin Resources based on 0.133 79North share for each Sumin share (a total of 3.34 million shares of 79North were issued).
Exploration by 79North started in earnest in August 2020. A LiDAR survey was completed in 2020 and our other data layers which consist of previous sampling, regional geology, artisanal mining areas, and airborne magnetometer/radiometric surveying, led us to outline 4 primary target areas for exploration named Marinara, Witlage, Pici, and Carbonara.
