Moose River Basin mounted Acker drill, designed to sample deep overburden and bedrock. A re verse circulation method using 69 mm diameter standard Drilco dual tube rods was employed to obtain chip and slurry samples at intervals of about 2 m. The drills were operated continuously on two, 12 hour shifts. The drilling started on February 4,1975 and was completed on March 27,1975. The geophysical studies consisted of a seismic survey for 72 km and a resis tivity survey for 84 km. Both types of survey were carried out along the road north of Hambly Township base line and a resistivity survey was also con ducted along the base line. Eight kilometres of combined surveys were done in parts of the road south of Hambly Township base line where the road was straight for at least 2 km. During the summer of 1975, a helicopter supported outcrop reconnaissance survey of the Moose River Basin was carried out and the lignite deposits at Onakawana were re-examined (Telford et al. 1975). The objective of this work was to determine which of the earlier reported occurrences of "lignite" outside Onakawana were true lignites worthy of follow-up studies. It was determined that, except for the reported occurrences along Coal River where it meets the Missinaibi River, and those of the Mattagami River and its tributary Adam Creek, most of the other occurrences were of Pleistocene peat. Palynological analyses of samples collected from outcrops of the Mattagami Formation along the Mattagami River near Smoky Falls suggested at least a late Middle or Late Albian (Lower Cretaceous) age for the unit (Norris et al. 1976). In 1975-76 another geophysical survey was carried out over the Onaka wana lignite fields (Scintrex Surveys Limited 1976). The purpose of this work was to determine whether existing geophyscial methods, particularly geo-electric techniques (ground as well as airborne) can be used as search tools to locate near surface deposits of the Onakawana type. The ground resistivity survey in dicated that there was no appreciable difference between the resistivity of the lignites and the clays associated with them. The airborne electromagnetic sur veys indicated two regions of relatively high conductivity, one to the west of the Ontario Northland Railway containing "within its confines" the known lignite fields, and another area immediately to the east of the Abitibi River. The sec ond zone included three anomalies and Scintrex considered them to be correla tive with the anomalies over the known lignite fields at Onakawana. In the Fall of 1977, three shallow holes were drilled on the anomaly loca tions east of the Abitibi River (Verma et al. 1978). In this operation, the equip ment was transported to Onakawana by rail car and camp was established at the Onakwana railway siding. The movement of men and equipment between camp and drill sites was by a Bell 206L helicopter. Hole 77-01 was 46 m deep (Photo 1.4), 77-02 was 50 m and 77-03 was 51 m. Sampling was done by split spoon sampler at intervals of about 2 to 3 m as well as by BQ wire line core bar rel giving continuous core recovery. The drilling commenced on October 11, 1977 and was completed on October 22, 1977. This investigation did not result in identification of significant quantities of lignite east of Abitibi River, but im portant stratigraphic information was obtained which will be useful in plan ning future exploration work in the Moose River Basin. Subsurface stratigra phy on the east side of the Abitibi River is significantly different from that on the west side, with Devonian bedrock forming local structural highs. In late summer of 1978 the third major Mesozoic drilling programme was 14

While preliminary results have been documented (Telford and Verma 1978), full details of the operation were not available for release at time of writing (January, 1979). Eight holes, totalling about 1176 m, were drilled in a general east-west direction along the southern margin of the Moose River Ba sin between Hecla and McBrien Townships. At the same time, an outcrop sam pling and reconnaissance programme was carried out along Adam Creek in Kipling Township (Verma and Telford 1978). Several of the drillholes encoun tered lignite seams and an in situ lignite outcrop was discovered in the bed of Adam Creek. Considerable study and laboratory analyses are presently being carried out on samples (core and chips) obtained during the drilling, and the re sults are to be transmitted in future reports of the Ontario Geological Survey. 15
