in Pine district consists OF the Sarah
Jane, Tom Boy and Saratoga lodes. All
OF these we'll known groups with other
claims are owned and operated by the
Imperial G. NJ. & NJ. company. Most Of
the above are patented claims and have
proven to have good veins. The Mackey
with over 1900 feet Of workings, all in
ore, has proven this to be large and
permanent vein carrying good values in
gold, silver and copper.
The Mackey is equipped with good
iron shaft house, friction hoist, eight

all the workings this vein has never
pinched, and that several hundred tons
shipped to the smelters have proven its

the slopes several hundred tons of this
ore ready for treatment.
The Cronje, another patented mine,
lying north and parallel with the Mackey
shows good strong vein similar to that
OF the Mackey, and carload lots from this
shaft over 100 feet in depth, gave returns
OF over Sii per ton. The other veins are
opened up by shafts from 20 to 100 feet

The Cyrene group is located just two

done on the Cyrene which has over SOC

The Sarah Jane group Just south OF
