Birch Lake Property, Red Lake District

Pelangio's Birch Lake property is located within the Birch-Uchi Greenstone Belt, approximately 120 km northeast of

the town of Red Lake, Ontario. Within an eight km radius of the Birch Lake property, there is a large gold resource

(Springpole Deposit) and a past producer (Argosy Mine) which produced 101,875 ounces of gold at an average grade

of 0.37 ounce per ton (reference: Ontario Geological Survey Open File Report 5835). Over the last decade, significant

exploration was conducted in this area by Gold Canyon on the Springpole Deposit , now controlled by First Mining .

The Pelangio land holdings are contiguous with First Mining’s claim s and approximately 3 km from the actual

proposed open pit (see figure 1). The Springpole Deposit is a bulk tonnage deposit which has proven and probable

reserves of 3.8 million ounces of gold and 20.5 million ounces of silver (121.6 million tonnes at 0.97 g/t gold and

5.23 g/t silver). Reference: Dr. Gilles Arseneau, Ph.D. , P.Geo. NI 43-101 Technical Report and Pre -Feasibility Study

on the Springpole Gold Project, Ontario Canada (2021).

Dome Exploration (Canada) Ltd. (later Placer Dome (“Placer Dome”)) and Trade Winds Ventures Inc. (“Trade Winds”)

completed the majority of the exploration work on the Birch Lake property to date. Initial exploration work by Placer

Dome consisted of mapping, geophysical and geochemical surveys along with diamond drill follow -up, resulting in

the discovery of the 70m wide, steeply dipping deformation corridor that yielded isolated high -grade gold

intersections. Subsequently named the High Grade Island Deformation Zone, high-grade gold mineralization within

this corridor is hosted by quartz -tourmaline-pyrite-arsenopyrite veins in the Main Central Zone. Secondary gold

mineralization associated with a folded banded iron formation (West Zone), that is proximal to the deformation

zone, has also been recorded.
