LOCATIOB

IMo property li*e about tvo ailes northwest of tyixke lake, a mile southwest of Little (fedrko lake, and about 27 '^ s^l** northeast of the tom of KLlnA River. Ihe property la north of and contiguous to the fedrke lake property of A.x goa Uraniua Mines Ltd. The south boundary of the Belfast property Iles abouJJ half a vile north of the Algon five-coB^artaentB shaft,vhieh is north of the ierpent Kiver and about tvo miles vest of (fcdrke lake. 5he Belfast property lies in the north-central part of township 150, Blind River Area, Sudbury Mining Division, Ontario*

ACCESSIBILITY

Thlo property aay be readied by driring fro* the Bain Sudbury-800 highway starting about three miles east of Spragge station on the C.P.R. Soo tine, and thence northward about thirty Biles along the newly constructed road to the Algom (feiirke lake shaft area, and thenco 01 foot half a mile to the north. The Bolfast property aoay also be reached by air from Lau-Ooma Airways base at Algona Mills, Out. on the Budbury-Soo highway to Little (^ilrke lake, a flight of 26 miles, and thence by trail for a aile southvesterly.

TMs group of volcanics, vhere mapped in the southeast and soith- central areas of the property, are aassive and fine-grained. They Vdather to a light pink colour, and tend to shov bending effects in tha hand speeiaen.. Petrologlcelly, hovever, certain of these consist of a rodt that is fine-grained and highly feldspathic, massive, and ponsequontly bearing an epHtlo pltitonle appeftranee* A dacitic semple vas noted aa a porphyritic type vlth feldspar phenocrysts and an aphanitic groundmass. Hence the rock appeare more probably a fine-grained, feldspar-porphyry.

Bhyolltet Kiie Is one of the *ost peoullar rocks encountered on the Belfast property. It If typically siliceous, and in places consists of a flinty chert. This la notably seen at the east and vest boundaries of the property e.g. on picket line Bo. 1*000 in a eeven-ft. vide out crop of the chert, it is found in sharp contact vlth a semi-foliated aetadlorite, The areal extent of its distribution is considerable, over a distance of tvo thousand feet in the south- central section of the property.

massive, medlum-to coarse-grained outcrops about 30^ hornblende, e. only distributed, as veil as About Pft ouartK phenocryst e, the balance being chiefly feldspar pheuocrysts*

Hornblende- Syenite: Thftse syenite* reaenthle the granite, generally, but lack, hovever, the quartv phenocrysts, except in occasional instances vhere they are noticeable, approximating five, per cent of the rock. A medium-grained type of the syenite occurs, containing feldspar pheno crysts. Bonce this particular section can be designated as a syenite porphyry.

Aplite Dykefll Samples of this rock v*re taken in vhich the matrix appears banded.The rock contains email- sited , thinly distributed naflc minerals, and hence la essentially a syenite vith a highly- feldspathic seal-massive matrix. fala pink, massive, fine-grained types of this rock also occur.

Feldspccr-porphyryt These dykes occur as plutonic rocks at distant intervals across the property.

One speclnen shew sericitic alteration, and is lightly banded vlth 03jt of mafic minerals present.

At the northvest corner a (rhyolitftt)chcrt contacts a foliated dioritio anddsite (tuffaoeous?) in this direction on line WOO. Further south, on lin* 1*800^ a hornblende granite is faulted across a narrotr fault tone in vhioh oecura a quarts -*-ein half an inch in vidth striking northveet. Anothr case is a gabtaro on lin* 1*800 S vhich is seal-sheared or foliated in a northwesterly direction. '

Tectonic forces resulted also in structural dislocations in a north easterly direction, e* g. a feldspar-porphyry is foliated northeasterly in the out crop Just south of the baseline on line 2000. Similarly an aplitic rock is stressed northeasterly 700 ft., south of baseline on line 2800.

A shatter zone in vhich narrow quartz veins traverse granite vae

noted across a width of forty feet. This is on the outcrop 150 feet north of the Algon boundaries on line 3000.

(b) Chalcopyrite i spotty signs of disseminated chalcopyrite vaa noted, associated vith a quart t-vein breccia. The latter is 20 inches vide, just south of the baseline on line 2000, in sheared feldspar-porphyry. It also occurs as bleba in amphibolite at the north end of line 1200.

(c) Pyrrhotite occurs in andesite near the north end of line 5200, and disseminated in~~fsnphibollte 650 ft. north of baseline on line 3600.

(d) Quart g veins Some of these might possibly carry gold values. Examplesof interest noticed are:

A ouartt vein stockwork forty feet vide in granite vas observed 150 ft. north of the Algom boundary on line 2000. A five-inch and a tvo-inch quarti; vein traverse a quartz- feldspar-porphyry outcrop 600 ft. south of the baseline on line 2000.Tvo four-inch quartz veins cut across hornblende-syenite 100 ft. north of the Algcu boundary on line 600. A one-half inch quartz vein vaa noied rilling a scarp fault line vhich crosses hornblende-granite on a hill 6^0 ft. north of the baseline on line WOO. A five-inch quartz vein vas observed 650 ft. north of the baseline oa line 3600.

Pyrite, chalcopyrite, pyrrhotite, and quarts veins are noted in eeveral sections of the property. These ocurrences, to gether vith the prominent east-vest structural fault and shear cones suggest the possibility of base and/or precious metal deposits.

Further exploration of the property for metal deposits is varranted.

It is recocmended by the writer that J

An electrical geophysical survey be undertaken over the entire Belfast property, using the existing picket line system as a grid control. Ibis should be of the self potential, resistivity, or electromagnetic induction type, carried out by an established reputable contractor.. Its purpose vould be to locate one or more anomalous areas vhich might contain economic concents&tions of oulphide

Diaaand drilling vould be dependant on the results of the a,bove- recoucDended geophysical survey.

All of vhich is respectfully submitted,
