I have been reading this report all dang day!........I am at page 78 ...of ....146 pages LOL.....Way way way more work was done of Rusty Ridge than ((( ANYONE EVER KNEW ))....I would like to give a shout out to my Libarian buddy in Kat Skype "the cutting edge of Kat DD(((( SHOUT OUT "HEY PJ GOOD WORK" ))) ...it is ineresting that those ...who consistently find the best DD....cant even post here....I wonder if that's a calculated effort....... on page 78...it says this is the next section lol....cant wait !!

INTRODUCTION
During the period 16 to 30 November 2001, Discovery Geophysics Inc. carried out magnetic and
gradient array induced polarization/resistivity surveys on the Holloway Cove and Ken’s Mountain
grids of Cornerstone Resources Inc. The grids are located on the South Princess property (Licence
7126m) on the Bonavista Peninsula in eastern Newfoundland. The surveys were carried out on cut
and chained survey grids that were completed by Ionex Ltd. of Springdale, Newfoundland just prior
to the arrival of the geophysics survey crew. The gradient array IP/resistivity survey was carried out
using an Iris ELREC-6 time-domain IP receiver with a Huntec M-4 2.5 kW IP transmitter powered
by a 6.5 Hp motor generator. The magnetic survey was carried out using three GEM Systems
GSM-19 Overhauser magnetometers and an EDA Omni IV base station magnetometer. The survey
crew consisted of Brent Robertson (chief geophysical operator), Dean Colbourne, Jeff Burton, Jerry
Whalen and Peter Hewlett of Discovery Geophysics Inc.
On the Holloway Cove grid, a total of 18.3 km of magnetic surveying was completed in one day and
a total of 18.3 km of gradient IP/resistivity in 5 days. On the Ken’s Mountain grid, a total of 21.5
km of magnetic surveying was completed in one day and a total of 21.3 km of gradient array
IP/resistivity in 6 days. The crew suspended survey operations on the evening of the 22 November
after completion of the Holloway Cove grid and returned on the morning of the 25 November to
continue with the survey on the Ken’s Mountain grid. The break was taken to allow the survey crew
time off and also to allow Discovery’s chief geophysicist time to assess data quality.
This report is a technical description of the surveys, data processing, and interpretation procedures,
followed by a general discussion of the results and their implications for the continued exploration
on the property. The total magnetic intensity data are presented in 1:5,000 scale profile, contoured
and colour gridded maps. The IP/resistivity data are presented as 1:5,000 scale profile, contoured
and colour gridded maps of apparent chargeability and apparent resistivity.
SURVEY LOCATION, ACCESS AND PHYSIOGRAPHY
The South Princess property is part of the Princess Group: a group of properties located on the
Bonavista Peninsula in eastern Newfoundland. The Princess Group of properties consists of 595...contiguous
claims and covers an area of approximately 149 square kilometres. The communities of
Canning’s Cove, Musgravetown and Bloomfield border the eastern side of the group of properties,
and the community of Bunyan’s Cove is located at the centre of the western side. The city of
Clarenville is situated approximately 7.5 kilometres south of the southern limit of the property
(Figure 1). The Holloway Cove and Ken’s Mountain grids are both located on the South Princess
property and fall within mineral licence 7126m on NTS map sheet 2C/05.
The Holloway Cove grid is located directly west of the community of Bloomfield and is easily
accessed from Hwy 233. The grid area is regularly used by locals to selectively harvest firewood
and as a result bush trails, accessible to all-terrain vehicles or snowmobiles, are widespread. A
woods road located about 300 m south of line 8000N parallels the southern border of the grid. The
topography of the area is gentle, except for the northeast corner of the grid, which is characterized
by an irregular pattern of steep hills. Low-lying areas are dominated by open bog or marsh interspersed
with forest. A large open bog is located between lines 9000N to 8600N near the western
end of these lines and extends for a considerable distance to the west. A dense growth of spruce and
balsam fir, interspersed with minor birch and aspen, covers much of the area. Exposed outcrop is
found on the higher ridges and hills, with little or no outcrop apparent in the low-lying areas.
The Ken’s Mountain Grid is located about 5 km west of the Holloway Cove grid and is accessed
from Bunyan’s Cove Forest Access Road that leaves Hwy 233 on the outskirts of the community of
Bunyan’s Cove. The forest access road is followed for about 8 km to the east side of the grid and
continues on to traverse the grid from east to west at about line 9400N. Clear-cut logging is
extensive along either side of this road, and skidder trails push into various areas of the grid where
wood was harvested. Total cut-over on the grid is estimated to be about 30% to 40%. Most of the
cutting is recent and as a result new growth has not yet developed and the logged out areas are
relatively open. Topographically the area is characterized by high ground to the north (Ken’s
Mountain) that slopes into a valley at around line 8800N and rises again to the south end of the grid.
Several small ponds and bogs are located along the valley bottom. Forest cover is a mixed growth
of spruce and balsam fir, interspersed with minor birch and aspen. Abundant exposed outcrop is
found on high ground and little or no outcrop is evident along the valley that extends the entire
width of the grid at around line 8800N...
SURVEY METHODOLOGY
Resistivity
The resistivity method is conceptually one of the most straight forward of all geophysical
procedures. Electrical current is applied to the earth, either on surface or in boreholes, using two
grounded electrodes, a powerful electrical generator and wire cables. At some location within the
generated current field, the electrical potential (i.e. voltage) is measured between two other
grounded electrodes using a sensitive voltmeter. Knowing the positions of all electrodes and the
intensity of current driven into the ground, it is possible to calculate the apparent resistivity of the
earth from the measured potential. The apparent resistivity is the effective resistivity of a uniform
earth which would give rise to the same measured potential.
There are a wide variety of arrangements of electrodes (i.e. arrays) for different exploration
purposes. To determine how apparent resistivity varies with depth, a spreading type of array is used
in which the distance between electrodes is increased in some orderly fashion and measurements are
repeated. To determine how apparent resistivity varies with position, and hence map the spatial
apparent resistivity variation, the electrode separation remains fixed and the array is moved with
repeated measurements. Some arrays can operate in both modes simultaneously, thus forming twoor
three-dimensional views of the earth.
The Wenner array is a spreading type array in which all electrodes are equally spaced along a line
with the current electrodes outside the potential electrodes. The Schlumberger array has all
electrodes along a line with the current electrodes outside the potential electrodes, but the potential
electrode separation is fixed while the current electrodes are symmetrically separated. In the
dipole-dipole array, the current electrode separation is set to the same separation as the potential
electrodes, and the dipoles are moved apart.
The dipole-dipole array is also used in a moving mode, but since all four electrodes must be moved
with each station, other less cumbersome arrays have been developed. The gradient array is similar
to the Schlumberger array except that the current electrodes are fixed at some large separation and
the potential electrode pair is moved about the region between them. The pole-pole array is
essentially half a Wenner array: one of the current electrodes and one of the potential electrodes are.........................
