The h i s t o r y o f the Groundhog Coal f i e l d i s w e l l documented i n
t he numerous open f i l e r epo r t s a v a i l a b l e f o r t h i s a r e a . Coal was
i n i t i a l l y d i s c o ve red a long D i s cove ry Creek i n 1903; f o l l o w e d by
some development work from 1904 t o 1913. The G e o l o g i c a l Survey of
Canada was a c t i v e i n the ba s i n i n 1948. Coas ta l Coal completed a
summers' mapping program i n 1966; w h i l e a j o i n t venture w i t h
P l a c e r Development L t d , Quintana M i n e r a l s Corp. and N a t i o n a l Coal
Co rp . mapped the area i n 1969 and 1970 and d r i l l e d i n 1970.

3.0 FIELD PROGRAM
A two man crew headed by J.M. Duford, P. Geol., began work in the
Groundhog Coal licence area in late August and finished in early
September, 1983. One to two days were spent on parts of the Groundhog
coal licences with the bulk of the exploration concentrating on the
surrounding area. The crew was mobilized from Smithers and supported
from Gulf Canada's Mt. Klappan camp, approximately 60 kilometres north
of the study area. A Glacier helicopter, on contract at the Mt.
Klappan camp, was utilized for the Groundhog field work.
The work consisted of applying the stratigraphy established in
1980 for the Panorama area to the Groundhog Coal licence area. Concepts
of the structural style were then developed for the licence area. Since
the outcrop is limited, data was acquired along the Skeena River and
from adjacent areas of high relief and applied to the geology of the
licence area.
Coal seams were exposed where feasible, logged and sampled for
proximate and 1.70 float/sink analyses. Analyses were completed by
Commercial Testing and Engineering Co. in Golden, Colorado (Appendix
C).
