Diamond Creek Phosphate Mine
Fully Integrated Mine-To-Market Asset
In-situ grade 23% P2O5
Available 12% P2O5
Organically certified
Located approximately 80km south-east of Salt Lake City, Utah, USA, Diamond Creek is one of the highest-grade organic phosphate deposits in the US. The mine is fully permitted, and the integrated mining and processing operation has compelling economics with a low capex, low-intensity seasonal mining operation. The in-house processing plant has flexibility to produce a range of sized and packaged organic rock products throughout the year and is ideally located for access to markets and Salt Lake City’s infrastructure and resources, including labour, supplies, industrial engineering and financial services.
Geology and Resources
The phosphate mineralisation comprises shale beds of the Meade Peak Member of the Phosphoria Formation and is a tabular orebody with mapped geological continuity, accessible from the South.
Diamond Creek’s mineral resource estimate from 1980 quotes 3.89Mt and 1.17Mt of surface mineable phosphate ore in the southern and northern sections of the project area respectively. Although the mineral resource has not been classified to international reporting standards it is based on a significant amount of work including historical production records.
The project has a pre-stripped area with production drilling information delineating approximately 2 years of planned production still in-situ. However there is significant scope to increase the current life of mine at Diamond Creek with historic “surface mineable resources” representing in excess of 60 years of production. Keras intends to establish a NI 43-101 compliant mineral resource at Diamond Creek as soon as possible”

Mining Season
The Mining season is permitted from 1 May to 30 November due to Forest Service restrictions, largely due to the amount of snow during winter months making access to the upper mountain impossible. Mining throughout the summer ensures that we have sufficient ore to feed our milling operations through the winter and fulfil annual sales requirements.
