Zinc and Lead.—In the occurrences of lead and zinc in the province, 
the ores of the two metals are usually associated. The principal localities 
are Notre-Dame-des-Anges in Montauban township, county of Portneuf; 
Calumet island, in the Ottawa river; the headwaters of Cascapédia river 
in the interior of Gaspé peninsula; and the Rouyn district. 
The only zinc property in Eastern Canada under actual production 
is the Tétrault Mine at Notre-Dame-des-Anges, 30 miles northwest of 
Quebec. Ore to the extent of 10,000 long tons a month is being extracted. 
The lead and zinc production in 1927 amounted to 7,729 tons of lead con- 
centrate and 21,839 tons of zinc concentrate. Of these quantities 6,496,577 
pounds of lead, valued at $341,461, and 17,189,046 pounds of zinc, valued 
at $1,064,690, were accounted recoverable. 
On Calumet island, 58 miles northwest of Ottawa, the occurrence of 
lead and zinc has been worked but further development is necessary to 
form an estimate of available tonnage. 
In the interior of Gaspé peninsula the important deposits of lead 
and zinc were discovered in 1910.* Development thus far indicates a 
large quantity of ore and it is expected that this will become one of the 
large zinc properties in America. Transportation facilities having now 
been established, it is expected that the property will soon reach the pro- 
ducing stage. 
In the Rouyn region exploration is being carried on most actively 
and with gratifying results. Should the Gaspé and the Rouyn deposits 
prove to be as promising as they now appear to be, the next few years 
should see a great increase in the production of lead and zinc in the prov- 
‘nee of Ouebec. 
Iron Ore.—Iron ore was first smelted in Quebec early in the 18th 
century and from that time till 1883 the industry was carried on almost 
continuously at Three Rivers in St. Maurice district. The output was 
small and the industry derived its chief importance from the superior 
quality of the pig iron made. The exhaustion of the ore bodies resulted 
in closing down this industry in 1911. 
There are numerous occurrences of iron ore in the province of Quebec 
but, unfortunately, most of these are titaniferous and are, therefore, 
refractory to smelting. Large deposits are known on the Gatineau river; 
in the Saguenay district; on the north shore of the St. Lawrence, but all 
of these generally contain titanium, and although such ores make high 
grade iron, they cannot compete with the lake Superior or Newfoundland 
ores for cost of smelting, 
Very large deposits of hematite have been reported as occuring in 
the interior of the province, near the headwaters of the Manicouagan
