The Panorama North occurrence comprises coal showings found above Beirnes Creek and in Wolf Meadows (an informally named, northwest-oriented valley found south of Beirnes Creek), about 132 kilometres northeast of Stewart.

The occurrence forms part of the southern Groundhog coalfield. The coalfield is an oblong (30 by 80 kilometres), southeast-oriented area extending from the headwaters of the Klappan and Little Klappan rivers to Groundhog Mountain. The Panorama North project hosts anthracitic coal seams.

Refer to the Discovery deposit (104A 078) for an overview on exploration history, regional geology and local geology of the southern Groundhog coalfield. The coal seams form part of the Lower Cretaceous Currier Formation (Bowser Lake Group) comprising carbonaceous shale, mudstone and sandstone.

Prospecting, mapping, trenching and sampling of the Panorama North occurrence by Gulf Canada in 1980 resulted in a speculative reserve estimation of 108 million tonnes (Coal Assessment Report 112). Upwards of 9 seams were encountered, however, the above estimation is based on the dimensions of the Currier and Leach seams (average thickness of 2.10 and 1.97 metres, respectively). Exploration in 1981 resulted in a revised inferred estimate of 240 million tonnes (Coal Assessment Report 113) for the combined Panorama North and South (104A 082) deposits. The most favourable area on the Panorama North property underlies Wolf Meadows where the coal seams are relatively flat lying.

Coal quality tests (Coal Assessment Report 112) based on trench samples gave the following average values:

-------------------------------------------------------------------

Raw Coal Washed Coal

Fixed carbon 55.9 65.6

Ash content 22.6 14.0

Volatile matter 17.8 18.2

Sulphur content 0.5 0.6

Calorific value 5,205 5,833

-------------------------------------------------------------------

All values are in per cent except for the calorific value which is in calories per gram. Washed values are based on a specific gravity separation of 1.8 grams per cubic centimetre which gave a float yield of 82.5 per cent. Vitrinite reflectance indicates anthracite rank.

In 2016, Atrum Coal Ltd. entered a farm-in agreement in which JOGMEC (Japan Oil, Gas, and Metals National Corporation) agreed to contribute $5 million in cash or in-kind support for three years to earn a 35% interest in the project. During the initial program (2016), multiple shallow coal seams were encountered, including a 2.3 metre thick seam at only 12 metres depth. In 2017, extensive surface mapping was undertaken to identify and trace coal seams, and five wide-spaced boreholes were completed, totalling 1227.5 metres.
