Sukhoi Log. Project history till recent days
Sukhoi Log is one of the largest undeveloped gold projects in the world. The gold mineralization that underpins this project was identified several decades ago and there have been many research projects to improve the knowledge of the deposit. Polyus secured management of the project in 2017 and has spent four years collecting new information, as well as verifying and testing the historic data. The result has led to a current report to the London Stock exchange of a Mineral Resource of 1,110 million tonnes grading 1.9g/t for 67 million ounces1. Studies continue and an Ore Reserve has been estimated and reported according to the JORC Code. In this paper, PJSC Polyus and AMC Consultants discuss the history of exploration, recent exploration programmes, data collection procedures and solutions to challenges presented during estimation of the resources. 1 As at 31 December 2020 - JORC Table 1 can be found at https://polyus.com/en/operations/reserves_and_resources/
