Following Governor Fitz Roy's visit, the water was analysed and advice given that it was best drunk as soon as possible after it emerged from the spring. While working for the Mittagong Land Company, in 1884, Edward Larkin improved the recreational facilities at the Chalybeate Spring, which lay on the company's land, and added a pipe to allow visitors to more easily obtain its water. The spring was one of the reasons for the establishment of a railway station at Mittagong. The NSW Railway Tourist's Guide of 1889 (page 26) states that at Mittagong, ""There are several chalybeate springs, one of which, near the town, flows into a bricked well, whence it is dispensed to invalids and others"". The water of the spring became well known. A newspaper article in 1909 attested to the popularity of the spring, ""The chalybeate springs right in the town are being availed of at all hours of the day. All who partake of the cool, sparkling mineral water are unanimous In their praise of its curative and invigorating properties. Many, indeed, are recommended by their medical advisers to visit the town for the sole purpose of availing themselves of a course at the chalybeate spring."" A newspaper article in 1921 described the facilities at the spring as follows:""The spring has been enclosed. There are summer-houses and seats, and provision made so that invalids taking the waters may rest and picnic, procuring refreshments on the spot. The waters have proved extremely beneficial to visitors, and are dally attracting others from all parts. The local Tourists' Association, recognising Its value, has taken great pains to make the spot comfortable and attractive." "  By 1938, mineral springs were no longer fashionable and the Chalybeate Spring at Mittagong had slipped from public consciousness. The iron ore mine and the Chalybeate Spring had co-existed for many years. The Fitzroy iron ore mining operation had been on a small scale, commensurate with the small capacity and sporadic operation of the 19th-century iron-works. In 1941, iron ore was again mined from a location close to the spring. Despite assurances that the spring would be protected, the mining activity caused the Chalybeate Spring to ‘deviate’ from its pre-war position. The land on which the Chalybeate Spring flowed had always been privately owned. In 1945, Nattai Shire Council was asked to approve a plan to erect poultry sheds at the site of the spring.
