Did you know…
John Mahon was the owner of a mica mine in the early 1900’s. Located just north of Murphy’s Point Park it was along the cross-country ski trail and called the Mahon Occurrence. Originally producing phosphate John took over in 1908 mining mica. According to government records nearly $4000 worth of mica was removed in just a few months. In today’s dollars that is the equivalent of $89,000. Give or take a penny or two.
The exact location will be on the self-driving tour map distributed during the Family Reunion.
On a personal note, I remember mum talking about family rowing across Rideau Lake to work the mine. I wonder if they sang “Hi Ho, Hi Ho, it’s off to work we go” during the crossing. —
The merry men of the Mahon Mine Occurrence. I believe John Mahon is the fellow on the far left. Other faces look familiar but if anyone can provide names please do so. —
Jo-Ann Rogers My Grampa, Joe Mahon used to bring me to the mica mine. I was fascinated with the ability to peel off the layers. Grampa was so proud of the mine and the family history that belonged with the mine!
Location: Lot 10, concession V, North Burgess township,
Apatite, phlogopite, pyroxene, calcite.
An old phosphate producer the mine produced
mica in 1908 under the direction of J. Mahon of
Rideau Ferry and continued intermittently until
- The mica workings lie a few hundred feet
southwest of the old phosphate pits, on a small
gully which has been worn out by water along a line
of pockets in dark green pyroxenite. A shaft
was sunk to a depth of 30 feet.
The mica occurs in pink calcite bodies in
fissures and pods in green metamorphic
pyroxenite. The mica is of good quality, but
small in size, the average being 2 by 3 inches.
The lead strikes N75OE.

This property belongs to Mr. J. Mahon, of Rideau Ferry, and
lies about a fourth of a mile to the west of Mr. Smith’s mine on lot 9.
Formerly an old phosphate producer, the mine lay idle until 1908, when the
present owner commenced work with three men, and has continued inter-
mittently up to the present time. The present workings lie a few hundred
feet southwest of the old phosphate pits, on a small gully which has been
worn out by water along a line of pockets in a dark green pyroxenite. These
pockets or chimneys connect horizontally by narrow fissures and are filled
out with large bodies of pink calcite in which the mica crystals are dis-
seminated. The latter are of fine quality, dark mottled-amber in colour,
and of rather small size, the average being 2″ X 3″. A depth of some
30 feet has been reached in a small shaft sunk on the largest of the pockets,
and several smaller openings have been made along the line of lead. The
direction of the chain of pockets is W. 15° S.,and indications tend to show the
existence of similar cavities to a considerable depth. The fact that water
never accumulates in the workings, but sinks away at once, is a very favour-
able sign. A little phosphate accompanies the mica. The present operator
lias taken out mica to the value of $4,000 in the space of a few months, and
there is little doubt that the mine would repay more extensive development.
