At Petra Diamonds Cullinan mine, the company is deepening the No. 1 and 3 shafts in addition to slope and line development. Work has also begun on blind sinking a ventilation shaft at Assmang’s Gloria mine.
“We are seeing a lot more opportunity on the continent in terms of new projects and while our order book has grown, we are hopeful to add additional projects in the short term,” concludes Widlake.
CEMENTATION USA SINKS THE DEEPEST LIFT SHAFT IN THE UNITED STATES
Cementation USA has completed sinking the deepest single lift shaft in the United States at the Resolution Copper Project in Superior, Arizona. With a finished diameter of 28 feet (8.5 m), the No.10 shaft was sunk to a final depth of 6 943 feet (2 116 m) below surface.
“Congratulations to the entire team, past and present, who have worked on the Resolution Copper Project,” said Justin Oleson, President of Cementation USA. “Completion of the No.10 shaft may not receive as much fanfare as some of the more visible wonders of the world, but the technical expertise and operational focus required to complete this project is certainly on the same level.”
“The successful completion of No.10 Shaft at Resolution is an achievement that the Cementation and Resolution Copper team should be extremely proud of,” said Mike Nadon, Senior Executive at Cementation USA. “The many technical challenges were overcome with good engineering and planning and our crews executed the plan with sincere regard for each other’s safety and consistent effort despite some very difficult conditions.”

CEMENTATION CANADA ENGAGED AS PRIME CONTRACTOR FOR COMPASS MINERALS
Cementation Canada has been issued a letter of intent by Compass Minerals to carry out the shaft rehabilitation and upgrades of two mine shafts at their mine in Goderich, Ontario. The letter of intent will allow engineering on the work to commence while a contract is finalised.
When the tenders were submitted for the shaft upgrade project, Cementation Canada proposed some alternate approaches to the design and installation of the new liners, which reduced risk to the mine operations and were of interest to Compass Minerals. Further work with the Compass Minerals technical team continues to examine innovative approaches that will add value to the project.
“We are very pleased to be working with Compass Minerals and the Goderich mine team on this significant and technically challenging project. The Cementation group has a long history of work at the salt mine and we recognise the importance of this project to Compass Minerals and the operations,” said Roy Slack, President of Cementation Canada.
The current Cementation Canada group was formed in 1998, but a former Cementation group sunk the original shafts: the number 1 shaft completed in 1959 and the number 2 shaft in 1968.
