Hemlo Project Noranda Mines Limit- ed is making commit- ments and carrying out work with the objective of developing a gold _ mine and a milling com- plex to mine and treat gold bearing ore in the Hemlo district of North- western Ontario. Subject to final review and confirmation, and to the recommendations of the feasibility study, which is scheduled to be completed at the end of May, 1983, Noranda is proceeding with the de- velopment based on pro- ject design criteria for staged production. The aim is to achieve a production rate of 1,000 tonnes per day at the earliest feasible date and to increase this so as to achieve mine pro- duction of up to 3,000 tonne per day of ore during 1987. A minimum life of some 20 years at the planned mining rates is projected. The discovery of additional reserves is a distinct possibility be- cause the orebody is still open at depth and to the East. In the Position Paper recently released by Noranda Mines Ltd., Hemlo Project, the Pa- per states that, ""Work has started on site, and the site clearing and installation of the 115 KV power line have been completed. It is ex- pected that the con- struction labour force will peak at about 700 on site, and that during the operating phase ongoing employment will be pro- vided for some 350 per- sons at the 3000 tonne per day level.' The. dispute with Lac Minerals has not been settled as of yet, how- ever, the situation is being addressed with the objective of achiev- ing an acceptable reso- lution. The options for mill location to be whether at the Geco Division plant near Manitouwadge, or at the minesite, were investigated and evalua- ted. Cost estimates and the increase in known reserves and consequen- tial increases in planned production rate were among the factors that lead to the decision to place the mill at the minesite. Ores will be primarily crushed underground and further crushed on surface through a con- ventional closed circuit secondary-tertiary crushing plant. Fine ore will be ground in a ball milling circuit and thickened be- fore passing to preaera- tion and leaching to ex- tract the gold. Gold re- covery will be by the carbon in pulp process followed by electowin- ning and casting into bars. The bars will be shipped for further re- fining elsewhere. Tailings will be de- slimed to produce hy- draulic backfill for the mine. Tailings slimes and sands not required by the mine will be im- pounded in the tailing disposal area, which is yet to be determined. The first stage instal- lations will have a pro- cess capacity of 2,000 tonnes per day. Addi- tional capacity will be designed and construct- ed to match the indicat- ed volume, type and. timing of available ore supplies from their own and other sources. It is likely to bring the total installed capacity up to 3,500 tonnes per day. The main production shaft will be a five compartment shaft and may be sunk initially to a depth of up to 1400 m below surface subject to confirmation from ex- ploration drilling. . Ini- tial production will be from higher levels and will commence at the earliest practical and feasible date at a rate of about 1,000 tonnes/ day. The strike zone widens out at depth and production, sufficient for a mill feed of 2,500 tonnes/day from the joint venture property, and 400 tonnes/day from the Teck Corona option, is planned. Bar- ring unforseeable events, it is expected that the shaft and under- ground development will be sufficiently com- pleted to start initial production by early 1985. Present indications are that the 25,000 tonnes per.day mining rate will be reached after some two years from date of initial pro- duction. The planning min- ing method is blasthole stoping with waste rock fill consolidated us- ing cemented tailings. Noranda states, "The orebody itself is shap- ed somewhat like a tall, but narrow and very thin book inclined at about 65 to 70 to the horizontal.

Who Else Makes Paper Ninety-three countries produce pulp, or paper, or both. Of these, 61 (including Canada) make enough to sell to other It is true that Canada by itself produces one third of all pulp and paper sold in world export markets. It is also true that Canadian mills and paperworkers set S| | world standards for quality. But the hard fact is, additions to pulp and paper manufacturing capacity are being built all over the world. Competi- tion is tough out there. Canada's industry is continuing to in- vest in updated and more efficient mills and other facilities to keep costs down. The competition for world markets will be won by the low-cost producers.
