SnapshotThe Willow Creek mine produces hard coking coal (HCC) and pulverized coal injection (PCI) product. The coal is processed on site then transported by rail to the Trigon Terminal.

Conuma Resources Limited completed a prefeasibility study in September 2022, and continued baseline monitoring for Willow Creek Extension project.

Deposit type

  • Sedimentary

Summary:

All of the deposits of interest for the Willow Creek property refer to the potentially surface mineable coals. In addition to “Deposit Types” the GSC Paper 88-21 also refers to “Geology Types”, which are a definition of the amount of geological complexity, usually imposed by the structural complexity of the area. The classification of a coal deposit by “Geology Type” determines the approach to be used for the Resource estimation methodology and the limits to be applied to certain key estimation criteria.

“The present study only addresses coal seams of the Gething Formation. There are seams present in other formations of the sequence in this area but their distribution and commercial significance has not yet been determined for the Willow Creek Property.

The Gething Formation seams of interest in this study are those numbered from 1 through 8 and Seam A. Another seam, referred to as Seam 9, achieves mineable thickness from place to place. This seam is not being considered for mining as part of the present study. There are other seams in this formation but these are too thin to be of economic significance.”

A minimum coal thickness of 1.0m is required to meet the criteria for inclusion to the mineral resource. Partings were considered separable from the seam if they were greater than 1.0m, and non separable if less than 1.0m. If the parting was greater than 3.0m, the seam packages were modeled separately, and considered as a repeat.

Seam naming has been kept the same, with the seams called Seam 1 at the top of the section and Seam 8 at the bottom. Seam A occurs in the north only, between Seams 4 and 5. On some sections a zero was added to the end of the seam name to identify seam splits (e.g. Seam 7 is represented as Seam 70 where intact and Seam 71 and Seam 72 to indicate splits).
