Exploration History

6/29/1988 The Consolidated Callinan Flin-Flon Mines Limited property, consisting of the AMIRILLIS, DAN, JANETTE, EOLA and FOUR QUEEN claims and also part of the Hudson Bay Mining and Smelting Co. Ltd. ML 5004, is located 0.5 to 1.5 miles (0.8 to 2.4 km) north of Flin Flon and east of Flin Flon Lake. Exploration began with trenching and diamond drilling in the 1927 to 1929 period followed by 19,000 ft (5791 m) of diamond drilling in 1937 and 1938, and 16,000 ft (4877 m) in 1949 to 1952. A geophysical survey was carried out in 1945, and a gravimetric survey in 1948. The foregoing was conducted on both sides of the Saskatchewan-Manitoba border. By 1938 the company had reported the discovery of a zone of copper-zinc mineralization 640 ft (195 m) long by 12 to 36 in (30.5 to 91.4 cm) wide. Further uneconomic quantities of chalcopyrite and sphalerite were intersected in 1951 and 1952. In 1965, an IP and magnetic survey as well as 4254 ft (1297 m) of drilling were conducted on the trend on the Saskatchewan side of the border. A further 15,663 ft (4774 m) was reported in 1968. As a result of the drilling and geophysical work, a zone of intense shearing and alteration consisting of chlorite schist, sericite schist, and chlorite-sericite schist was traced over a length of 5000 ft (1524 m) and a width of up to 400 ft (122 m) lying along the contact between porphrytic andesite breccia and amygdaloidal andesite. The zone is probably the main northern extension of the Flin Flon ore zone. An additional 4,774 m of delineation drilling was completed in 1968. In 1969, Hudson Bay Exploration and Development completed an ground EM survey over the property (AF 63K12-0060). This work was completed on the JOHNNY BARON, VIRGINIA, FOX TROT OH DON’T and MARY E claims. Between 1976 and 1979, Hudson Bay Exploration completed a 1,472 m long exploration drift at the 1,690 ft level that extended from the North Main shaft to the Callinan Deposit. Revised reserves figures were released in 1978. Between 1980 and 1981, Hudson Bay completed an extensive underground delineation drill program on the deposit. Surface drilling conducted between 1984 and 1985 to the north of the South Callinan Deposit intersected the North Callinan Deposit. By 1986, 17,882 m of delineation drilling had outlined two separate zones of sulphide mineralization that contained at least 6 separate distinct suplhide lenses. Revised deposit reserves were released in 1989. In March 1988, Manitoba Mineral Resources entered into an agreement with Hudson Bay Mining and Smelting to purchase a 49% interest in the deposits. Consolidated Callinan Flin Flon Mines retains a 6.67% net profits interest in the property. In 1989, a drift was driven at the 2,210 foot level from the North Main shaft to the Callinan Deposits and a second drift was planned at the 2,750 ft level. In February of the same year, Hudson Bay completed ground VLF-EM and magnetic surveys over the WAN 12 grid on Q-1303 (formerly MARY E claim), Q-1281 (formerly VIRGINIA claim) and Q-1105 (formerly JONNY BARON claim), Q-1289 (formerly FOX TROT claim) and Q-1290 (AF 63K13-0060). Drill hole FOX TROT-1 was completed on WAN 12 grid on Q-1289 (AF 63K12-0167). No significant values were intersected in this hole. In April 1990, mining of the Manitoba portion of the Callinan South Deposit commenced. At this time the combined deposit reserves were given (Northern Miner: 4/02/1990, pB11). From 1992 to 1993, Hudson Bay Exploraion completed drill holes 4Q-48, 50, 51, 54, 61, and 62 on the old OWENS claim and completed drill holes 4Q-49 and 55 on the old FOUR QUEENS claim to further test the Callinan Horizon at depth (AF 63K13-0073). Drill holes 4Q-49, 50, 51, 55, and 62 intersected Cu-Zn values within metavolcanic flows. From 1993 to 1994, Hudson Bay completed drill holes FFS-8 to FFS-11 and 4Q-65 to test a favourable Quartz Porphyry Horizon which is located in the footwall of the Main Mine Horizon (AF 63K13-0074). The drill holes intersected pyrite and pyrrhotite with minor chalcopyrite. In 1994, new deposit reserve figures were generated. In 1996, underground drill hole CX-901 was completed (AF 63K12-0082) and existing drill hole FFS-012W2 was deepened (AF 63K12-0194), In the same year, four drill holes were completed to test the Quartz Porphyry Horizon (AF 63K12-0190 and -0191) and detailed geological mapping was completed on this showing (AF 63K13-0084). In 1997, holes FFS-015 and -016 were completed (AF 63K12-0199) and bore hole PEM surveys were conducted (AF 63K12-0200). In the 28 May, 1998, Northern Miner, Hudson Bay announced the discovery of the new 777 (Triple 7) Zone at the Callinan Mine. The zone lies between 800m and 1,500 m below the surface. At the same time, revised reserves were released for the Callinan Mine. In 1999, Hudson Bay Exploration and Development completed drill holes 4Q-72 to 4Q-76 on the Callinan North Mine or CAL MINE grid (AF 63K13-0089). The holes were completed to test the mine horizon geology and to test the mineralization up plunge. In the August 2001 Mining Magazine, HBM&S announced that the 777 Mine shaft had broken through into the Manitoba portion of the Callinan mine workings at the 600 m level. In 2001, Hudson Bay completed drill holes FFS-023 and FFS-024 on the Callinan grid between the deposit and the Flin Flon mine deposit to test the west quartz porphyry horizon in the stratigraphic footwall of the Flin Flon deposit (AF 63K13-0092). No significant sulphide mineralization was encountered. On 8 October 2004, it was announced that Ontzinc Corporation had purchased Hudson Bay Mining and Smelting from Anglo Ameriacn International SA for $325 million and that the company was to be renamed Husdon Bay International Minerals Corporation. As of 1 January 2004, Hudson Bay reports Callinan Mine production and reserves as part of the 777 Mine production and reserves.
