REFERENCE LETTER

Scientific Production Centre GEOKEN LLP carried out a ground electrical survey in Aktobe and Kostanay regions of the Republic of Kazakhstan under the request of ERG Exploration LLP. The surveys were conducted in order to identify potentially promising areas for identification of polymetallic ores.

According to the Scope of Works, the electrical survey was conducted at 8 areas. The survey was conducted in the period from June 2022 to September 2022. The scope of electrical survey work was 119.7 line km.

The works on the project were carried out by using modern, most advanced specialized technologies and software products. GDD Instrumentation GRx8-32, Txll-5 electrical survey complex was used for data recording. Topographic support was performed with Trimble R12 system.

As a result of the work, 3D models of electrical properties were obtained, potentially promising areas for the identification of polymetallic ores were identified, and recommendations were formulated for the location of exploration wells. The obtained materials, in combination with other geological and geophysical data, were used for geological mapping and allowed a more reasonable approach to solving the problems of the geological structure of the work area and identifying promising objects.

During its operation, GEOKEN SPC LLP has established itself as a reliable partner that has the necessary human resources, modern equipment and software for high-quality and timely performance of electrical exploration work.

Sincerely, General Director A.Z. Shalabaev
