Tolmie Property
Property Description, Location & Access
Belmont's 64 unit (1024 ha) property is located in north central
Tolmie Township, Porcupine Mining Division, Ontario.
Local Infrastructure
A high voltage powerline that connects the power generating stations
on the Abitibi River at Abitibi Canyon (25 km NW) and Island Falls
(12 km S) with the main provincial grid passes in a north northwesterly
direction 5 km to the west of the property. Both the Ontario Northland
Railway line between Cochrane and Moosonee and Highway 634 between
Smooth Rock Falls and Fraserdale run N/S some 10 km west of the
property. The town of Smooth Rock Falls lies approximately 50 km
SSW.
Exploration History
Two companies have previously worked the claims now owned by Belmont.
In 1978 Hudson Bay Oil & Gas Co., Ltd. flew a combined electromagnetic
and magnetic survey over a large area that included the northern
1/3 of Tolmie Township and hence the Belmont option. An anomalous
area immediately to the west of the property was surveyed with follow-up
ground electromagnetic (em) and magnetic methods. Although the em
response was verified the orientation of the anomaly was inconclusive
and no further work was done.
In 1987 Continental Precious Metals Inc. held a total of 25 claim
units in three small blocks all of which are now covered by the
present Belmont option. Results of a ground magnetometer survey
revealed a generally east/west magnetic trend within which two roughly
circular anomalies, one a magnetic high approximately 200 m in diameter
and the other a magnetic low roughly 600 m in diameter were delineated.
These anomalies, which were reported to correspond in location to
air photo features, were believed to represent intrusive bodies,
possibly kimberlites. One drill hole was recommended to test the
circular magnetic low, but was never drilled.
Published government data for the region include the compiled geology
as well as the results for a reconnaissance airborne magnetic survey.
North and northwest striking structural features (probably faults)
interpreted from the magnetic data cross the claims.
Regional & Property Geology
There are no rock exposures on the property or in the immediate
area, however, the compiled geological data implies that the area
is underlain principally by east/west striking quartzfeldspar-biotite+/-garnet
schists of probable volcanic and/or sedimentary origin. The schists
have been intruded by large granitic bodies and to a lesser degree
by diabase and lamprophyre dykes.
Structurally, the property is well located at the intersection
of the northwest trending Lake Timiskaming Structural Zone with
the north to northeasterly striking Kapuskasing Structural Zone
(Map
1). Four known clusters of kimberlite pipes - Attawapiskat,
Spider, Kirkland Lake and New Liskard - are associated with the
Lake Timiskaming Structural Zone. Individual pipes within the Attawapiskat
and Spider clusters are known to be diamondiferous. Similarly, diamond
bearing lamprophyre dykes located in close proximity to and thus
probably associated with Kapuskasing Structural Zone have been found
near Wawa.
Exploration Potential
Belmont's Tolmie Township property has potential for the discovery
of kimberlite pipes and thus diamonds for the following reasons:
- The property lies at the intersection of the Lake Timiskaming
Structural Zone with Kapuskasing Structural Zone.
- Northerly and northwesterly structures (probably faults) interpreted
from the available aeromagnetic data cross the claims.
- Kimberlite pipes or related intrusions, some of which are diamond
bearing, are associated with both Structural Zones.
- Discrete magnetic anomalies underlie the claims. Two anomalies
are associated with air photo features that may be bedrock related.
