Alan W. Pope MARGINAL NOTES Minister Natural LOCATION AND ACCESS John R. Sloan Resources Deputy Minister Lundy Township is located in the District of Timiskaming. 20 km west of Ontario the Town of New Liskeard. It is bounded by Latitudes 47°29'39"N and 47°34'50"N and Longitudes 79°53'17"W and 80°00'58"W Only one good road provides vehicular access into the township. It ex ONTARIO GEOLOGICAL SURVEY tends for a distance of 1.5 km, close to the boundary of concessions II MAP P.2733 and III. from a paved road leading from Highway 65 to the Twin Lakes cottage area The road ends at a beaver pond and splits into trails which GEOLOGICAL SERIES - PRELIMINARY MAP extend into the central and southwestern parts of the township. Similar trails are present in the northeast as continuations of lot line roads ex tending south from concession road II in Henwood Township (i.e. the GEOLOGY AND MINERAL DEPOSITS eastern boundary of lots 4 and 1). A trail also extends westward as a continuation of concession road V in Hudson Township. All concession roads eventually join with Highway 65. LUNDY The northwestern part of the township is accessible by float plane on Lundy Lake or by a new hunt camp trail leading south from Henwood Township to this lake Access to the southwestern part of Lundy Town ship is by boat on the Montreal River from a public dock at Mowat Land TOWNSHIP ing. The only dwelling currently inhabited is located in the southern half of lot 2, concession V. A seasonal hunt lodge is located on the northwest ern shore of Lundy Lake in lot 10, concession IV. TIMISKAMING DISTRICT MINERAL EXPLORATION Scale 1:15 840 Discovery and development of silver-bearing veins near Cobalt in 1903 prompted an extensive prospecting boom throughout much of this part of the north. Although only 1 property is described from Lundy Township (Resident Geologist's Files, Ontario Ministry of Natural Resources, Co- balt), discovery of undocumented old pits and trenches during field NTS Reference: 31 M/12 mapping attest to the early exploration undertaken in the area. ODM-GSC Aeromagnetic Map: 1493G A single recorded mineral occurrence (Property 1) is located in the ©1985 Government of Ontario southeastern corner of lot 4. concession V. The claim was initially pro spected by the Alex J Godzik group in 1953, and worked later by Harold Walton in 1972. Ten shallow pits were blasted in a 125 by 175 m area, Parts of this publication may be quoted if credit is given and the material exposing sporadic copper mineralization in lower Lorrain Formation is properly referenced quartzose arenite, and younger diabase dikes. Assays including 2.52% copper over 4 feet (1.2 m) were obtained (Resident Geologist's Files, This map is published with the permission of V G. Milne, Director. OntarioGeologica l Survey Ontario Ministry of Natural Resources, Cobalt). Minor and sporadic claim staking occurred in the northeastern part of the township between 1945 and 1970 along a Nipissing diabase intru sion. Unsubstantiated reports describe copper and cobalt mineralization from numerous pits within this diabase but locations were poorly identi fied. In 1973, a gold-bearing boulder was discovered by Mr Messenger in the northeastern quarter of lot 1, concession V. The ground was optioned to The International Nickel Company of Canada Limited (now INCO Lim ited) but nothing further was discovered The boulder was found in till and contained 16 ounces gold per ton in a quartz-carbonate gangue. In 1906, a headline in the local newspaper (New Liskeard Speaker) an nounced that gold-bearing copper was discovered in Lundy Township The article stated that a property was acquired by H.C. Barker and asso ciates and hosted a 2.5 foot (75 cm) wide vein averaging 6.5% copper and $4.00 gold per ton (equivalent to 0.24 ounces gold per ton in 1906) No current or past producing mines are known. No geophysical or geo chemical surveys have been performed and no diamond drilling has been undertaken. LOCATION MAP SCALE 1:1 584 000 Within a 4 km radius of the township, occcurrences of silver, cobalt, cop per, and pitchblende have been previously described from rocks similar to those exposed in Lundy Township. In order to investigate the potential for these minerals, a ground radiometric survey was carried out with a LEGENDa McPhar TV-1 spectrometer by the author, in addition to extensive litho- geochemical sampling. Reliable background values for many of the common trace elements found in Cobalt-type rocks were subsequently PHANEROZOIC derived and possible anomalous areas defined. CENOZOIC QUATERNARY GENERAL GEOLOGY PLEISTOCENE AND RECENT Glacial glaciofluvial. swamp, lake, and stream The map area is underlain by Early Proterozoic Lorrain and Gowganda deposits Formation sedimentary rocks of the Cobalt Group of the Huronian Super group. The rocks were subsequently intruded by a moderately-dipping UNCONFORMITY diabase sill and steep-dipping diabase dikes and plugs of Nipissing age. Middle Proterozoic diabase and olivine diabase dikes intrude all older rocks.
