It is not possible at present to de- finitely indicate the geographical boundaries of the region in which the gold-bearing quartz claims occur. Al- ready about 10,000 claims represent- ing an area of about 400,000 acres haVe been recorded. It must not be taken for granted that gold-bearing quartz. Veins occur on all of these claimsnpossibly some of the claims do not show quartz veins of any kind.

The most important deposits so far located lie to the east of the Mattaganii River in the Townships of 'l‘isdale and Whitney, but, recently discmeries have been made' to the West of the Mattagami in the 'l‘own~ ship of Bristol in the “ripple (‘reck district. l. llcnlnu'ival Relationships.

The following report is in general based upon 0h- uervationa in the l’urvupine district. The most important information regarding the l’oreupine gold tields mntained in a report by A. (3. Bar- I‘uWa entitled “The l'oreupine (Sold Area" was published by the Ontario Bureau of Mines in Hill. Many other reports have appeared in the techni- eal press, partieularly in the ('ana- dian Mining Journal. published in Toronto. ln ailtlitiun to these the Bureau of Mines has already issued a reeoiinaisanee map of the l’oreupine district on the scale of one. mile to the ineh. This map indi'ates the geology in the vicinity of the “ol- linger and Home and is accompanied by a brief Keolouival statement of Prof. W. (l. Millet; Xatnrally, this map is not romplete and in the. later editions the topography and geology will appear in greater detail. 1 wish to add that Dr. M. Maelaren very kindly indicated to me the geologi- eal relationships in the Township of 'l'isilale and further that l haVe hail the benefit of the examination of nu- merous specimens by the Geological SurVey at Berlin. The discovery oi gold‘bearing quartz veins in the neighborhood of Porcupine in 1909 is the most im- portant made in Ontario since the discovery of the nickel deposits of Sudhury in 1%} and the silver veins at Cobalt in 1903.

The strike and dip of the veins is very variable. Sometimes the veins are only a few centimeters across; on the other hand, they occasionally ex- pand and form enormous quartz masses which. like domes, rise above the surrounding country. These vein formations seldom occur singly, but rather form series of veins and stringers approximately parallel,con- etituting a broad zone of veins.

This quartz contains gas and liquid inclu- sions, as well as feldspar crystals and line needles of tourmaline. As a result of earth morements the quartz is much fissured and, consequently, easily broken. Along with the quartz, aiderite and a brownish mineral with rliumlvuhedl‘al cleavage ~â€"~ ankerite «('aMgFe) (‘Uâ€"are fairly prominent. In a rein on the. West. Dome mine, ankerite is the chief mineral in which the quartz forms only slender string- ers running across the win.

The ankerite sometimes earries a little gold, but this has been derived from the solutions which introduced the quartz.

Only at the very sur- face may the decomposition of the sulphides and ankerite be observed. In this rusty mass the gold Values are higher. This slight eVidence of «ecundary enrichimnt is rarely mark- ed at a depth greater than two to three metres. 'l‘he distribution of the ore seems to he most uniform when the ore body occurs in strongly disturbed and lissured country rock. This is particularly true in the awe of the schistose quartz porphyry. ‘Under such circumstances the rising ore-car- ryini,r solutions could penetrate 0V- erywhcre freely and consequently found numerous points of contact with the country rock. A belt of quartz porphyry of this kind, now largely altered to sericite schist oc- curs in the vicinity of Pearl Lake. (Concluded next week.) Suvh explorations are strongly re- t'ommended also on account of the constant Variation in the size of the vein. From this point of View the ex- posures at the Jupiter mine are very instructive. Here the milky quartz containing scales of sericite and tour- nialine,needles is well banded with light and dark bands. It is well ex- posed from the surfaCe to about four- teen metres belothe ground water level, and is of a fairly uniform char- acter. The gold, which is linly divid- ed. may be seen without the aid of a lense. occurs in the natiVe lorm and is scattered through the fresh quartz in such a manner that. not- withstanding the high values. one may not regard it. as the product of secondary enrichment.
