The Horse Terrace Sluicing Company, Limited ; Offices, Auckland. Secretary, Mr. H. Gilfillan, junior. This company was formed with a capital of £5000. It acquired from McDougall Brothers, two holdings of twenty acres each, situated at Horse Terrace, ten miles from Murchison; and, in addition, a special claim of 100 acres was taken up. Operations were commenced in November, 1904, and have been carried on continuously since that date. A race, two miles and a-half in length, and six feet in width, was brought in, carrying thirty-five Government heads of water. Power is held to bring in 100 heads, and it is proposed to exercise this power when fuller development work has been carried out. Two faces are at present (1905) being worked. An up-to-date electric light plant has been installed, and gives a 92–16 candle-power. Twelve persons are employed. A sawmill in connection with the works is driven by a six-feet Pelton wheel, and supplies the timber used in the claim.
