Later in the year, the building, weighing 1,840 tonnes, was moved over the course of three months along teflon-coated concrete beams to its present location, which is easily accessible via a footpath from Seddon Street.
159:. The mine became one of the most important gold and silver mines in the world. By 1952, when the mine closed, around 5.6 million ounces (174,160 kg) of gold and 38.4 million ounces (1,193,180 kg) of silver had been produced from 11,932,000 tonnes of ore. The modern Martha Mine has operated as an

Some environmental protests occurred during the 1987 consenting process for further mine operations. In 2001, subsidence in the area caused a collapse of a house, and the operating company has recently agreed to pay compensation to about 130 households for various negative effects due to noise, blast

The horizontal
Cornish pump was used up to 1913 to raise water from a depth of around 400 metres (1,300 ft) via the adjacent No 5 shaft at a rate of over 400,000 litres per hour. After 1913, electric pumps were used to dewater the mine, but the pumphose was kept in working order until 1929

William
Nicholl marked out a 5 acres (20,000 m) claim, calling it "Martha" after a family member. Several smaller claims were later merged to form the Martha Company. By 1882 the first battery to break gold-bearing rock was in operation. The Martha Mine eventually grew into one of the world's

In 2001, the area surrounding the pumphouse was fenced off, following subsidence in nearby Barry Road. Investigations reached the conclusion that the only way to protect the building was to relocate it to a safer site. The operation to move the

to update the machinery. Although the technology was available to do this, the money was not. Manpower issues also factored into the decision to close the underground mine. There had been two World Wars and the
Depression of the 1930s, depleting manpower and creating a difficult economic climate.

In 1935 New
Zealand gold output peaked during the depression, with two-thirds by the Waihi Company which was the largest of the four major companies. That year for tax reasons the Waihi Company was split into three, including the Martha Company which controlled the Martha Mine.

Starting in 2004, a series of underground mines all accessed via one entrance, the Favona portal, have been developed. These mines, (Favona, Trio and
Correnso) run under much of the town of Waihi - and produce approximately 100,000 ounces of gold each year.

From the 1930s onwards, the building had been stripped of all machinery and left in an increasingly derelict state. In 1983, the building was registered as a

Some internal steel bracing remains installed in the building and it is able to be viewed by the public during daylight hours.

By the 1950s the mine was struggling due to a series of factors. Chief among those was the international gold price, which was
