ACG Mine Closure 2024
The mine closure industry will meet in person from November 26th through the 28th in Perth, Western Australia, for the Australian Centre for Geomechanics (ACG) Mine Closure 2024 convention.
The series of International Conferences on Mine Closure is a fixture on the calendars of many mining professionals. It provides topical, high-quality papers and presentations on a range of topics of immediate interest and relevance. A key feature of the conference series is the diversity of disciplines and expertise that come together to focus on the pressing issues facing the mine closure community globally.
This year they are focusing on the UN Sustainable Development Goals (SDGs) framework.
SLR is proud to be a Session Sponsor for Session 9: Mine Closure Planning and a major sponsor.
We are also thrilled to be exhibiting (booth 17) at the upcoming convention. Our global mine closure team will be attending and ready to share their expertise and are looking forward to meeting up with you.

Fort Collins aggregate mine planning for closure: optimising post-closure land use through mine operations
Jeremy Scott Collyard (co-written with Mark Arigoni) | Thursday, November 28th at 13:50
The Mine is a construction material aggregate mine outside Fort Collins, Colorado. Operating successfully for over 40 years, the mine is now nearing the end of its operational life. International Corporation assisted in the preparation of a mine planning update and vision that focused on meeting all regulatory obligations and optimizing the post-closure land use. Understanding that the closure obligations are defined by the state of Colorado Division of Reclamation, Mining and Safety (CDRMS) and the United States Army Corps of Engineers (USACOE), the project team worked collaboratively to evaluate, assess and develop a mine closure plan that delivers a project that not only meets regulatory requirements and is financially viable, but is also socially and contextually conscious, and allows for the successful operation of the mine in its remaining years.
The existing mine property is uniquely situated within a myriad of land uses that include agriculture, commercial, institutional, and residential. With the surrounding community context in mind, the potential post-closure land uses were evaluated for land value, compatibility, constructability, costs, implementation schedule, and future land use risks. Potential feasible post-closure land uses were defined and evaluated including residential, commercial, wetland mitigation banking, agricultural, recreation, and combinations of uses.
This approach required a multi-disciplinary team consisting of mining and civil engineers, landscape architects, ecology and wetland specialists, cost estimators, property valuation specialists, and permitting specialists. Conceptual closure alternatives were defined and evaluated resulting in a combination of post-closure land uses. Although the selected alternative resulted in a reduction in the aggregate to be mined, it was selected based upon the assessment of all criteria discussed above. This paper will present the process, alternatives, and the mine and closure plan as developed for the Timnath Mine.
