An early lease that comes to light as a separate locality on Mindat due to the discovery by George Peel in 1891 regarding silver minerals. The location is the first discovery of native silver in New Zealand. This occurs in a 12 inch thick bluish-grey quartz vein called the South British Leader, which drops into the Hanging Wall of Dixons Reef. Silver is found as very narrow irregular shoots parallel with the walls of the leader, the mineral described as 'shining scales', resembling the look of mica, giving a bright metallic lustre when rubbed. Associated is black sooty powdery un-named probably silver oxide material. Also associated is considerable quantities of pyrargyrite, and petzite is also noted. Uneconomic. One tonne was sent to the Thames School of Mines to be tested. A specimen was sent to the Auckland Museum. The species list for this locality is incomplete.

Formerly known as the Clunes Mine although little information was found. The Clunes level is mentioned for the New Alburnia Mine early 1890's, with the Clunes and New Whau companies amalgamated in 1896. Prospecting on the Dixons Reef in the Clunes Mine is reported in 1908.

As the Nordenfeldt most information was found in the early 1890's by individual miners. Antonio Sarich tried to have the mine forfeited in 1892 for non-working, however the warden issued a fine instead. Another fine for the same reason was issued the following year. John Kneebone is noted as owning the mine in 1889-1891, A.R.S. Thorburn 1892, John Nolan 1895, then later in the year the mining inspector declares the lease forfeited for non-working.

(Bell, 1910) states the Nordenfeldt syndicate, also known as the John O Groats operated the mine 1890-1894, at the stage of publication part of the Old Alburnia Mine. Even taking into account that different sections could be worked by different parties, some maybe tributers, and various sections heaved off into neighbouring leases, there is a discrepancy between the newspaper articles and Bell yet to be resolved.

The mine is located in high country between the Shellback and Tinkers Creek. The Mindat co-ordinates are approximate.
