The fragmental breccia
is moderately to strongly altered and infused with finely disseminated pyrite (iron sulfide) in the breccia
matrix, in the breccia
fragments and in cross cutting veinlets.
pipe is a vertical pipe-like column of broken rock, which, because of the coarse-grained and initially porous nature of these breccia
pipes, allowed mineralizing fluids that passed through some pipes to deposit a large suite of metallic minerals.
In hand specimen, leached, oxidized, and sheared San Diego breccia
consists of cobble to boulder sized, sub-rounded aphanite clasts in a dark gray, amorphous silica matrix.
The Twilight Zone breccia
and San Pedro breccia
are mineralized zones within and adjacent to granodiorite igneous rocks, thus there is an important relationship between the sedimentary rocks, veins, breccias
and intrusive rocks at Vianey Mine.
Within EL 23121, four diamonds were reported in the northern part within streams transecting the main Merlin NNE structure containing the recently tested Perceval breccia
at the Merlin Diamond Mine by North Australian Diamonds Limited.
It is in one of the most prolific breccia
pipe areas in the NPSP with several breccia
pipes per square mile (owned by the Company) over an adjacent area of about 14 square miles.
With acquisitions in the North Pipes project area of Northern Arizona, Liberty Star additionally now has 771 standard Federal lode mining claims covering 15,960 acres or about 25 square miles in 46 separate blocks covering 143 breccia
4 square miles in 4 blocks including 16 new uranium breccia
pipe targets (Pipes).
The primary target is an intrusive-related breccia
pipe hosting copper-gold mineralization.
containing clasts of diorite porphyry and basalt was intersected downhole to 554m depth.
E[acute accent]Sudbury Breccia
(Psuedotachylite) is the known host structure for ores in the Sudbury Footwall type deposits.
