The application of CRIRSCO, JORC, NI-43101 and NAEN standards in assessing the geological reserves of metal ores and other solid minerals was considered in practical terms at a seminar in London from 11-17 November 2018.
Mark Campodonic, Director and Consultant, SRK (UK) shared extensive experience in auditing mineral reserves and preparing reports on reserves and reserves with delegates from Kazakhstan and Russian geological and mining companies. This topic is particularly relevant now for the Republic of Kazakhstan, where in 2018 it was decided to introduce international standards for reporting reserves and reserves of KAZRC / CRIRSCO.
Phil Newall, CEO and Dr Yulia Cherepanova from Wardell Armstrong, Luke Balleny from the International Mining and Metallurgical Council, Hilco van Moerkerk, GEOREKA software developer HvM, Michael Pernette from Canadian Geosoft and others also spoke at the seminar.

The managers and specialists of Evraz and Norilsk Nickel studied the organization of work at two concentrators at Somincor’s Neves Corvo mine, the Portuguese branch of the Canadian company Lundin, and heard technical reports from leading automation and productivity specialists in the enrichment and logistics units. Great interest was also aroused by the reports of Mark Yseboodt – Siemens AG, Harri Hokka and Harri Lehto – Outotec and Eugen Becker – Thyssenkrupp.
At Neves-Corvo, the workshop participants met with managers and specialists and visited two concentrators at the Somincor mine. At one factory capacity of crushing and enrichment of copper ore is 2.6 million tons per year.
The second factory with a capacity of 1.0 million tons per year, originally intended for the processing of tin, is now producing zinc and copper concentrate.
In both factories, equipment for secondary crushing, grinding systems with rod and ball mills, flotation cells, and systems for compacting and dewatering concentrate are installed.
At the processing complex, additional equipment was mounted for re-grinding of copper tailings with the aim of additional extraction of copper and zinc concentrate from old tailings.
The total number of personnel in two factories that work in five shifts is 219, which also includes maintenance workers, workers of the tailing dump, water purification and drivers of transport for the processing plant.
The mining village of Castro Verde pleasantly impressed the Russian processors with their well-groomed, modern design of houses and a comfortable hotel.

A representative delegation of leading specialists and managers of oil and gas and drilling companies of Russia and Azerbaijan participated in the program of technical visits organized by the Transeuropean Centre and the international drilling conference in Celle.
It was here in 1859 that the first oil well in Europe was drilled. Now in Celle – Hanover there is a cluster of oilfield services companies and manufacturers of innovative equipment for the oil industry.
Participants of this business trip made detailed acquaintance with mobile drilling rigs, coiled tubing units, installations for automatic connection of pipes and other equipment for drilling and production of oil and repair of wells on offshore and onshore platforms.
The delegation visited the technology and production centers of the companies Baker Hughes, Max Streicher GmbH, KOLLER Solutions, Instral BV and Weatherford, as well as the Drilling Simulator Celle at the Clausthal Technical University.
Among the participants of the event were senior managers and engineers of LUKOIL-Nizhnevolzhskneft, Tatburneft, Drilling Systems Co., Gulf Drilling Supply Azerbaijan and Tyumen Industrial University.

From October 23-25, we organised a visit to Boliden’s mine at Garpenberg in Sweden, in addition to a visit to the Atlas Copco office in Stockholm and the test mine and technology center in Orebro. Leading mining companies Norilsk Nickel, Evrazholding, Arselor Mitall Temirtau, Zaporizhstal, EuroChem, Uralenergoresurs and other participated. The participants got acquainted with the experience of the Swedish companies Boliden and Lundin after achieving record performance due to the automation of underground works and digitization of production processes.
