The lease was first pegged in early 1893 by James McGregor and George Cundy, but it was left un-worked for months, probably due to attention being focused on their Old Nell lease. No surface quartz was showing at Maori Dream, and it was dismissed as worthless. 15 acres. The lease then went through a succession of owners in the space of a few years. The lease borders the Phoenix to the south-east in one source, and borders the Phoenix Mine on its north in another.

The next set of prospectors was Withers and party, who dug a trench finding a seam initially 0.5 inches thick, but increasing to 10 inches as work progressed. The vein was flat lying near the surface, however changed to vertical at depth. Mining was via quarrying into the hill-side. Two tonnes of ore was sent to the Thames School of Mines, and a further 5.5 tonnes to Kuaotunu.

A visitor in 1895 stated the lease had been prospected only, but had garnered more attention than most of the other leases in the area. He states the prospectors are inexperienced, being saw-millers by trade. Across 1894 to 1895, Joseph Smith owned the lease. Henry David Abbott applied for a lease as the Maori Dream Proprietary around the same period however it is uncertain if it was the same property.

Reubens or Rubens Kerry held the lease and others nearby early 1896. The London based Maori Dream Gold Mines Ltd took over later in 1896. They amalgamated it with the Kauri, Morning Light, and Ohui Extended leases. Some bills were left unpaid, blamed on their attorney. In 1899 Edward Ryan of Auckland had the lease forfeited to him from the Maori Dream Company. He re-named the lease the Meroia.

In a 1912 report, the lease is now named Dreadnought, or in some other sources Tairua Dreadnought. The old adits for the Maori Dream have collapsed. The host rock is altered pyroxene andesite, the vein hard white quartz, rust coloured from oxidation near surface, with banded structures, remnant pyrite, and Au-Ag values. The vein averages 15 inches wide, to a maximun of 4 feet wide, flat to shallow dipping, situated at the base of the hills.

Mineralisation is found in a sinuous fracture, 100 feet long, with gold in oxidised near surface un-named sulphides, the vein described as forming wavy bands, migrating from one side of the reef to the other, and containing rich ore (although little evidence of substantial mining was found).
