NTS Grid: 42D14NE, 42D14SE
Point Location Description: Unknown, approximated from map in AFRI 42D14NE0006
Location Method: Conversion from MDI
Access Description: The claim group is centred approximately 10 km north northeast of the town of Terrace Bay, about 3.5 km north of Highway 17. The group straddles the common boundary of the Lower Aguasabon Lake Area, Syine and Strey Townships (claim maps G 599, G 634 and G 633 respectively). The claim block area is crossed by a Kimberly Clark haul road which leads from Terrace Bay.
1971: An airborne EM survey was conducted by Kennco Explorations Limited over the area including the Bel Air claims. 1982: The claim group was staked. 1983: All interest was transferred to K.A. Gracey (in trust). A 19 claim group was optioned by Bel Air Resources Limited. An airborne geophysical (VLF HEM electromagnetic and magnetic) survey was conducted by Orequest Consultants Limited and prospecting and sampling was carried out. 1984: Bel Air Resources Ltd. carried out trenching and sampling.

Geological Age: Archean
Dec 07, 2005 (B Nelson) - Property geology is described by *Cavey and Barnes (1984): The property is occupied primarily by generally east west trending ridges and cliffs of Early Precambrian (Archean) mafic metavolcanics with intercalated lenses of early Precambrian (Archean) intermediate metavolcanics and minor metasediments. The southern half of the property is also occupied by large ridges and rock knobs of Early Precambrian (Archean) mafic intrusive rock comprised of amphibolitic gabbro. North south and east west trending Middle to Late Precambrian (Proterozoic) mafic intrusive dykes of diabasic composition are found throughout. The overall foliation trends vary from east-west to west-northwest, east-southeast. Dips are generally vertical to 70 degrees north and south. Associated with an intermediate metavolcanic lens within the northeastern quarter of the property is an intercalated lens of wacke and black grey chert containing magnetite and minor disseminated pyrite. Metamorphosed mafic intrusive rock, labelled as amphibolitic gabbro, is observed as topographical highs throughout the southern half of the property. The gabbro is dark green fine to coarse grained and characteristically massive in outcrop. East west and north south trending mafic intrusive diabase dykes are found throughout the property.
| Rock Type | Rank | Composition | Texture | Relationship | Mafic lava flow-unsubdivided | 1 | Basalt | Aphanitic, Sheared | Host |
|---|---|---|---|---|
| Gabbro | 2 | Amphibolitic Gabbro | Near | |
| Diabase | 3 | Diabase | Near | |
| Intermediate Tuff | 4 | Tuff-Lapilli Tuff | Near | |
| Porphyry-unsubdivided | 5 | Pophyritic Flow | Near | |
| Sandstone | 6 | Wacke | Near | |
| Vein | 7 | Quartz | Host |
Dec 07, 2005 (B Nelson) - The mafic metavolcanics are comprised primarily of dark green foliated, aphanitic rocks of basaltic composition that have been largely amphibolitized, magnetized and calcium carbonatized. The very fine grained variety has slaty structure. Amygdaloidal flows containing amygdules of calcium carbonate as observed as well as pillowed lava flows, porphyritic and tuffaceous flows. Vesicular textures are very prevalent. Where in proximity to the mafic intrusive gabbro, the mafic metavolcanics are frequently observed as amphibolite and/or amphibolitic schist. The diabase is easily distinguishable from the gabbro due to the equigranularity of the diabase versus the metamorphosed, often amphibolitized nature of the gabbro. The diabase is sometimes olivine and quartz bearing and has a distinctive rusty buff weathered surface.

Dec 07, 2005 (B Nelson) - On the east bank of the Aguasabon River is a rusty quartz vein containing up to 20 percent pyrite. *Cavey and Barnes (1984) reported that: Analysis of humus and soil samples yielded scattered anomalies in most elements. Encouraging assays in gold, molybdenum and arsenic have been outlined. Gold anomalies which range between 30 675 ppb occur mainly as scattered isolated anomalies. Partially coincident to the gold anomalies, areas of gossan and disseminated pyrite were observed. Rock samples taken have indicated no base or precious metal concentrations. In general, values are low.
