The Berg property sits immediately northwest of Imperial Metals’ Huckleberry Mine and the Ootsa property sits immediately to the southeast. The Berg and Ootsa properties are adjoining on the west side and combined they cover the majority of the Seel-Huckleberry-Berg porphyry trend, having a total combined area of 120,155 hectares. Mineralization at the Berg deposit forms an annular shape around a broadly cylindrical, multi-phase intrusive stock known as the Berg Stock. The historic resources comprise two highly fractured mineralized zones in the northeast and southern portions of the annulus. Hypogene mineralization is characterized by several generations of veining, and a well-developed supergene enrichment blanket is superimposed on the hypogene mineralization.
A total of 53,754 metres over 215 holes have been completed on the deposit by prior operators including Kennecott, Placer Dome, Terrane Metals, and Thompson Creek Metals. Drilling in most areas of the Berg deposit remains wide-spaced and mineralization is open to depth and outward from the Berg Stock. The deposit has been shown to have excellent vertical continuity with significant mineralization intersected greater than 550m below surface.

Cu Eq %*
*Cu Eq. (copper equivalent) has been used to express the combined value of copper, molybdenum, and silver as a percentage of copper, and is provided for illustrative purposes only. No allowances have been made for recovery losses that may occur should mining eventually result. Calculations use metal prices of US $3/lb copper, $22 silver, and $10/lb molybdenum using the formula Cu Eq.% = Cu% + (Mo% x 3.33) + (Ag g/t x 0.0107).

1This resource estimate for the Berg Deposit was prepared in accordance with NI 43-101 standards and is considered by Surge management to have a high degree of reliability, however, the resource has not been verified by Surge and is considered historical in nature. A qualified person representing Surge has not done sufficient work to classify the historical estimate as a current mineral resource or reserve and Surge is not treating it as a current mineral resource or reserve. This resource was estimated for Thompson Creek Metals Company Inc. in a 2018 Technical Report titled "Updated Technical Report and Mineral Resource Estimate on the Berg Project, British Columbia" by James Barr and John Huang of Tetra Tech Inc. The estimate is based on 201 drill holes and 51,622 metres of drilling and used ordinary Kriging interpolation constrained by an open pit using a 0.25% Cu Eq cut off.
