The Hauraki Gold Mining Company was registered in London in late 1894 to take over several old claims covering the hill between Coromandel town and McGregor Bay. It also controlled leases in the Kapanga and Tokatea areas, north-east of Coromandel, with the Scotty and Royal Oak mines respectively the centre of attention for the company in these areas in the late 1890's.
Like all the companies which came before and after it, rich specimen stone was found in the upper levels, however these patches never went to any extent, and gold at depth was poor. However, it did provide material to display, and generate investment capital. The company was more successful than most at Coromandel, but again only lasted a few years as the general poor grades of the ore could not keep pace with expenses. Native arsenic is found associated with the gold. Stibnite rare.
There were several companies in the area which went by the Hauraki name. The Hauraki Main Lodes Limited covered 100 acres, and was operational in the late 1890's on the old Albion, and Albion Extended claims, covering a large area of the foreshore where the hill described above meets McGregor Bay. It was adjacent to the Hauraki and Golden Pah mines. Work was focused on intersecting the Hauraki and Union Beach lodes. E.A. Daldy was mine manager.
The Hauraki (New Zealand) Associated Gold Mines Limited in the late 1890's held claims at the Tokatea Range summit, north-east of Coromandel, covering the old Pride of Tokatea, Caledonian, Oriana, and Rising Sun Extended claims. The leases covered a total of 86 acres, and contained a 10 stamp battery. Mine manager was Henry Franklin Shepherd.
The Hauraki Consolidated was formed in 1898, after entering a joint agreement with Metals Trust Ltd to form Port Hills Gold Mines Ltd. Its purpose was to prospect the Venus Reef, which is south of the Kathleen Gold Mine in the same general vicinity as main Hauraki Mine.
The Hauraki Mine was called the 'old Hauraki Mine' at later times, largely used to distinguish it from the neighboring North Hauraki lease, which then became the Hauraki Reefs lease. The Hauraki Reefs Limited was formed in 1910, and took over the Hauraki Freehold Property, comprising the old Welcome, Hauraki North, and Golconda leases, as well as 50 acres of the Wynyardton freehold. This came with a 15 stamp battery on the Welcome lease.
Meanwhile there was a New Hauraki lease, but this was in the Success mining area, to the east of Coromandel. This company was liquidated in 1901, and had its assets sold at auction in a fire sale.
These entities were operational from the late 1890's and into the first two decades of the 20th century. In 1914, the Hauraki Reefs company had closed down due to a lack of capital.
In 1919, the Hauraki Mines Ltd was formed, but little information was subsequently found. This operation closed in 1923.
Around 1929, the Hauraki Consolidated Company had been formed, who reported coarse leaf gold found in the newly named Stockwood Reef, accessed from the old Hauraki Mine shaft. They had deepened the shaft from 400 to 550 feet, then drove towards the Union Beach and Hauraki reefs. The specimen stone had been found where the Stockwood Reef intersected the Union Beach Reef. They were also trying to intersect Legge's, Castle Rock, Green Harp, Block 5, 6, and 7 reefs. The mine was sold in London from this company in 1932.
