Early History
Callery’s Battery sits in the hinterland of an area traditionally associated with the Kāhui-tipua, Te Aitanga-a-Rapuwai, Waitaha, Kāti Māmoe and latterly Kai Tahu iwi. Travelling routes along the Waihemo, Te Hakapupu (Pleasant River) and Waikouaiti awa enabled access into the interior for many generations of iwi.
Key coastal settlements at Moeraki, Matakaea (Shag Point), Waikouaiti, and Huriawa (Karitane Peninsula) attest to the rich resources in the area supporting those vibrant communities for generations. For example, the Waihemo awa was recorded by local Ngāi Tahu kaumātua, Merekihereka Hape and Rāwiri Te Mamaru, as a kāinga mahinga kai (food-gathering place) where tuna (eel), īnaka (whitebait), pātiki (flounder), raupō, aruhe (bracken fernroot), and pipi were gathered. The mouth of the river was a shelter for waka, a place of sea and freshwater fishing, and a habitat for fur seals and moa.
Inland and to the west, Pātearoa/ Rock and Pillar Range, was a place of mahinga kai particularly for weka and tikumu/mountain daisy. Stone resources, particularly silcrete, were mined at different inland quarry sites and transported as blade blanks for use at coastal sites such as Matakaea
Mining history
Mining is one of the major themes in New Zealand’s history and has a ‘great impact on New Zealand landscape.’ Otago was one of the principal areas of mining (along with the West Coast and the Coromandel). Gold mining took two forms – alluvial gravels and quartz bedrock mining. Scheelite was an important ore of tungsten used in the steel industry. It is sometimes found in association with gold bearing deposits, and was also mined in Otago – with the most significant scheelite deposits at Glenorchy and near Macraes, including an area known as Golden Point.
One of the most important areas of quartz bedrock mining was at Macraes, inland from Palmerston in Otago, known to Māori as Ōtī and an area associated with seasonal food gathering. Quartz mining required money, men and equipment – the rock had to be mined, crushed, and treated to extract the gold. Such processing required large plant and buildings, as well as motive power such as water power or steam power using coal as fuel. Both alluvial mining and quartz bedrock mining left characteristic landscape effects: alluvial mining left its logical sequence of water races, reservoirs, sluicing faces, tailings and tail races, while quartz mining left shafts and adits, mullock heaps and battery sites.
Quartz mining was capital intensive: quartz was blasted from the bedrock, tunnels dug, ore crushed and gold extracted with cyanide or mercury. Much gold was lost in this process. While gold was more easily extracted from the top oxidised layers of rock, returns dropped as mines went deeper, and the gold could not be chemically liberated as easily. The first quartz mine to be worked in the Macraes area was at the Eclipse Reef in 1866, which by 1868 had become known as the Duke of Edinburgh. A stamper battery was built in about 1868, but had stopped working by 1872. Local quartz mining then proceeded at a number of sites, including in the area of the present Golden Point Historic Reserve, where at least five different batteries have operated. Callery’s and its predecessor, McGill’s operated at the same location. Two main ore bodies bound this reserve, and were served by these batteries: the Maritana Reef and the Golden Point Reef.
The Maritana Reef was probably discovered in 1889, but unless some small-scale work was carried out by the Donaldson brothers in association with the Golden Point Mine, work did not commence until 1902. The Charles Hay’s Maritana Quartz Mining Company was operating in the area in 1889, pegging out a claim on a reef, close to Golden Point – and perhaps giving the name to the reef. The Mount Ida Chronicle reported in September 1890 that a number of reefs had recently been discovered around the Macraes area – notably the Maritana, the Golden Point and the Orient, and had looked to be good prospects, with only a lack of capital preventing progress.
Another mineral was found in association with the gold deposits and added to the history of mining near Macraes. Scheelite, the main ore of tungsten, was also mined and processed in the vicinity of Golden Point. Along with mines at Glenorchy, this was one of New Zealand’s most significant scheelite mines. Scheelite was found in quartz veins, often in association with gold. Scheelite mining began in New Zealand in the 1880s, with ore exported to Germany. The scheelite trade with Germany ended with the declaration of war in 1914, with Britain buying New Zealand’s scheelite. Scheelite was used in steel manufacture, and was used to strengthen steel and in weapons manufacture.
It was difficult for miners to save both gold and scheelite from the ore, as they require different techniques. Scheelite is most efficiently saved as coarser grains (sand size), but that size of particle does not release much gold from sulphides, or even from quartz. Miners had to decide whether to save gold or scheelite, a decision usually reflecting the price of the ore. Callery’s Battery at Golden Point was used for processing both gold and scheelite.
Around 1902, the Maritana Mine was opened by Charles McGill, and McGill erected a six stamp battery powered by a 16 feet diameter [4.8 metre] water wheel to work the reef. McGill had prior experience in South Africa. The reef was found to be gold bearing, but highly refractory (resistant to cyanide processing), and a small concentrating buddle (a shallow container in which ore is washed) was installed in 1903 to improve recovery. In 1905 a Frue vanner (a machine used to separate ore) was added again to improve the saving of concentrates, and a nine bhp oil engine was installed to provide motive power during dry weather.
Despite this extensive development work, the 1906 Warden’s report commented that gold returns were small, and by 1907 work had ceased at the mine and battery. At this point the history of the Maritana Mine and its batteries becomes more complex.
In December 1909 the Inspector of Mines reported that a Timaru syndicate was about to reopen the mine, but it was not until 1911 that the Maritana Mining Company was floated and began operations. The new company purchased a ten stamp battery from Barewood and re-erected it beside the mine to the east of the old battery, which was still standing. The new battery was linked to the mine workings by a tramway, these workings probably being further around the hillside to the north from the earlier mine of 1902-1907.
In 1912, the West Coast Times reported that the Maritana Company was expected to begin crushing scheelite in three months, ‘an expensive and modern plant having been erected.’ In 1913 the company was working with a ten stamp battery and employed eleven men. By 1913 levels one and three in the mine were worked out. Prospecting in ground adjacent to the Deep Dell property came to nothing, and the mine closed down that year. In March 1914, the Mount Ida Chronicle reported that the Maritana mine was abandoned.
In 1914 W.H. Bickerton and party purchased the old Maritana Mine machinery, including the battery, with the intention of relocating it to their workings at Nenthorn, where they had pumped out some of the old shafts, but there is no evidence that the machinery was ever re-erected there.
In the meantime, the original Maritana Battery was still in existence on its original site, even if in a much-modified form. The Callery Brothers took over this battery, and continued to modify it until the present form took shape, probably with none of the original machinery remaining (although some original timbers may have been recycled in the structure). During the 1940s scheelite was in high demand because of the war effort. Callery and party worked the Round Hill Mine, and transported the ore to the Callery’s Battery, known at the time as the ‘Deep Dell Battery’ for treatment. Note that this battery is not the old Deep Dell Battery nearby at Horse Flat (site I42/13).
Scheelite mining (at both the Round Hill and Golden Point Mines) and processing continued until at least 1951, with the occasional return to gold mining depending on the fluctuating prices of the two commodities.
In 1980, the land was donated to the Department of Lands and Survey by members of the mining syndicate that still owned it. In 1985 the wider Golden Point area was gazetted as an historic reserve. In 2019, Callery’s Battery remains part of the Golden Point Historic Reserve and is accessible to the public, with interpretation panels explaining the site. The Battery is operated at irregular intervals.
