Cactus Cu-Au-Ag Breccia Pipe
The Cactus project comprises of at least three intrusive, hydrothermal breccia pipes including the historic Cactus copper-gold-silver mine.
Mineralization is hosted within a series of outcropping quartz-tourmaline-chalcopyrite-pyrite breccia pipes. The Cactus, Comet and New Year pipes, as well as two others not previously mined (Colburn and Purity,) are aligned along a west-northwest trending structural corridor 1,000m long by up to 400m wide. The breccia pipes appear to have preferentially developed in areas where the structural corridor is cut by northeast-trending cross faults.
The Cactus prospect features:
- Significant historical production from the central Cactus breccia pipe, which was mined across an area 200m long by up to 55m wide to 275m depth.
- Wide zones of copper mineralisation remaining within the mined area defined in subsequent drilling;
- historical drilling and channel sampling, which has outlined significant mineralization remaining within mine boundaries; and
- iIndications of a widening mineralisation at depth from historic mining data (level maps) and drilling.
Historical mining at the Cactus mine occurred until 1915 and stopped when mining activities reached the mining claim boundary. Alderan now holds the mineral rights to all adjoining titles.

Alderan commenced drilling at Cactus in 2017 with the objective of testing at depth and along strike for extensions of mineralization. Drilling results from this ongoing program can be found at the following link
