PROSPECTUS.
The Directors of this Company have secured, by agreement,
the grant of the Mathilde Nines, situate at the foot of the
north-western spurs of the Harz Mountains, close to Neuen-
krug, and distant about two miles and a half in a northern
direction from the town of Seesen, and forty miles from the
city of 13,1113SWiCk. The area of the grant is about twelve
hundred statute acres.
The surface of the property from east to west is free from
break or interruption, whilst in a transverse direction it is
depressed into a slight curve, having its greatest depth near
the line of the main road.
The geological position of the property included in this
grant is precisely identical with that of the celebrated Mans-
field Mine, and there can be no doubt but that the cupreous
bed so long and profitably worked by the Mansfeld Company
also exists in the present grant.
The thickness of the copper-bearing schist, at the points
where it has been examined, is very uniform, and the en-
gineer reports it to exist, with little variation in this re-
spect. throughout the greater part of the lands included in
the concession.
The strata overlying the Kupferschiefer offer no difficulty
to the operations of the miner. The cost of piercing them
must necessarily vary with the dimensions of the shafts.
Labour can be freely drafted from the Ober Harz. and the
scale of wages payable for an eight hours' shift is one third
less than is paid in England.
Materials of every kind are readily procurable in the vari-
ous markets of Prussia. Saxony, and Westphalia, and cm be
transported to the mines by means of the railway 'which
passes directly through the property.
The Royalty payable to the Decal Government is 1-20th
of the value of all Ores raised, sold or smelted. No mini-
mum rent is imposed, neither is there any State supervision
calculated to prevent the free and unrestricted development
of the property.
The copper schist deposit is only known to exist in the
Mansfeld district, at the foot of the Harz Mountains and
New Brunswick, British America, but it has alone been
worked at Mansfield.
The value of this property and the regularity of the pro-
duce of the cupreous beds may be best estimated by reference
to the following, statistics of the Mansfeld Mines, the weekly
yield of which at present is upwards of £B,OOl worth of sil-
ver, and £16,000 worth of copper.

ABSTRACT OF MR. BLAKE'S REPORT.
MATTI ILDE MINES, NEAR aEESEN, lIALIAUSEN,
FOREST-REVIER HAHAUSEN, GERMANY.
This property, consisting of 1,200 acres of land, held under
grant from the Government on liberal terms, is situated about
three miles north-east of the town of Seesen, and is Inter-
netted by the railroad from Brunswick, and also by the public
road from Seesen to Goslar ; it consists of a basin of sedi-
mentary rocks, underlying N.W. at an angle of 12 deg. from
the south boundary of the property, and extending from W.
to E. through its whole length until cut off at the eastern
boundary by an upthrow fault, on the east side of which are
the clay, slate, and porphoretic rocks, forming the northern
portion cf the Harz Mountains.
The peculiar value of this properly is the existence of a
bed of bituminous shale of the same character as the cele-
brated Mansfeld Mines. The shale is here eight inches thick,
with four inches of copper sandstone, while in Mansfeld it
is only four inches, and the sandstone ore is absent, but it is
found at Sangerhausen, and is more productive of copper
than the shale. The contents of which average in Mansfeld
14 per cent of copper The identity of the bed is also proved
by the fossil fish which are found between the lamina of the
shale, and all in one position doubled up, having been all
dead before being enclosed in the rock.
The existence of this bed, under the whole property, has
been proved by the shafts marked on map S.. K., H., in the
eastern portion, and two in the western, markek L„ in all of
which the shale maintains the same character and strength.
The depth from surf ace is, on the south side, about 30 feet ;
and, in the deepest portion, where the main shafts should be
placed, marked M., wilt not exceed 100 feet, while the depth
of the Mansfeld Mine is 203 to 400 feet. f here is also an ab-
sence of water, which offers great advantages in the cheap-
ness of working. This property being of quite an exceptional
character, I considered it right to visit Mansfeld, to ascertain
for myself the method of treatment of the ores, and also the
cost of working and extracting the copper and silver ores,
which have rendered these mines so famous. The weekly
yield being at present £B,OOO worth of silver and £16,000 worth
of copper from eight mines. The nature of this ore is such
that it is treated at a mere nominal cost, and without any ex-
pensive chemical or patent process, and the ores at Mathilde
lilines can be all treated in the same way.
I now give you a statement of the expenses required, and
the results which may be depended upon as being correct,
the prices having been carefully ascertained from Mr. Asses-
sor Hausmann, of Brunswick, the head Government engi-
neer, and carefully checked by personal observations and in-
quiries at Ma.nsfeld, wages being here one-third less than in
England.
I have, therefore, no hesitation in recammending you at
once to complete the purchase of this most valuable property,
which contains over 4,000,0'30 tons of ore ; 1,200 acres elves
54,140,0i0 feet, which,
at 14 cent per foot, will yield a
grzsv_v_alue of over £s' 000,000 of copper, and allowing one-
ing Zruseis, will yield £2,500,000 profit, without includ-
ue of the siIver.ABSTRACT
