Jameson Resources (ASX:JAL) said that independent technical advisers reviewed its bankable feasibility study for the Crown Mountain hard coking coal project in British Columbia, Canada, and the competent person for the study remains valid based on the review of the updated information, according to a Friday Australian bourse filing.
Since the release of the study in 2020, there have been inflationary increases in both capital and operating costs in Canada as well as in competitor producer locations, the filing said.
The review identified the range of capital and operating costs increases based on the repricing of key capital equipment items and the adoption of published increases to labor, fuel, construction, and infrastructure costs.
The outcomes from the review using the updated economic inputs resulted in an estimated increase of 28% to the project's pre-production capital from $309 million to $394 million, as well as a 15% increase in cash operating costs from $89.41 per tonne in the yield optimization study to $102.79 per tonne.
The review also considered the impact of revised coal price forecasts and exchange rates.
The firm's shares jumped over 33% in recent trading on Friday.
