MT^OT) AVn INTT-rrtlMU'-.TATION OF 1«5SULTS - ELECTR0MA.GNET1C SURVEY
Opera tin/; PrincipJ o; V]ien an electrical conductor is subjected to a
primary altornatinc field, a secondary current is induced in the
conductor. This current produces a secondary alternating field
wliich together Avith the primary field produces a resultant field of
different amplitude and phase from the applied primary field. Tliese
differences may indicate the presence of a conductor.
Operation; The battery-powered transmitter sets xip a ]irimary field
while the in-phase and out-of-pliase (quadrature) components of the
complex secondary vertical field are detected by a receiving coil
and measured by means of a compensator-amplifier unit located a fixed
distance from the transmitter unit, Tlieso parameters are expressed
in percentage of the primary field,
Conductor Rcco/yiitioii; The typical curve over a steeply-dipping coixductoi'
shows a low (negative - greater than y/o) over the centre of the
conductor, flanked by positive readings on both sides of the conductor,
riotli the in-phaso and the out-of-pliase components usually produce
the same general shape of curve. An asymmetrical curve may indicate
one or more of tlie following conditions: (l) more than one conductoj^"
(2) variable conductive overburden (3) a shallow dipping conductor.
Conductjvity Determination; l io ratio of the amplitudes of the two
measured components, in-phase to out-of-phaso, is directly jiroportional
to the conductivity of tlie conductor, in areas of non-conductive
overburden.
Conductox' bocation; For a single conductor, both component readings are
normal.ly zero wlien either tlie transmitting or receiving coil is
directly above the conductor. The location of the conductor is cal
culated by adding one-half the distcuice between tlie transmitting coil
and the receiving coil (coil interval) to the co-ordinate at wliic}i
the readings arc zero. A unique solution is generally not possible
in the case of multiple conductors s])aced less than one coil interval
apart. This results in tlic possibility that an apparently wide
conductor may actually consist of two or more narrow conductorso
Depth of Pcnotration; Tiie maximum depth of ])cnotration for detection of
a stoc]>ly-dip])ing conductor in a gco-el ectrlcally neutral background
is about 0,7 times the coil interval. Uvor }iori/;ontal or flatly-
di])jiing condvictors, ])cnetrotion of up to 1,5) times tlie coil interval

Notice of Intent
for Technical Reports
1984 04 27
2.6153/57-83
An examination of your survey report indicates that the requirements of The Ontario Mining Act tiave not been fully met to warrant maximum assessment work credits. This notice is merely a warning that you will not be allowed the number of assessment work days credits that you expected and also that in approximately 15 days from the above date, the mining recorder will be authori?ed to change the entries on his record sheets to agree with the enclosed statement. Please note that until such time as the recorder actually changes the entry on the record stieet, the status of the claim remains unchanged.
If you are of the opinion that these changes by the mining recorder will jeopardize your claims, you may during the next fifteen days apply to the Mining and Lands Commissioner for an extension of time. Abstracts should be sent with your application.
If ttie reduced rate of credits does not jeopardize the status of the claims then you need not seek relief from the Mining and Lands Commissioner and this Notice of Intent may be disregarded.
If your survey was submitted and assessed under the "Special Provision-Performance and Coverage" method and you are of the opinion that a re-appraisal under the "Man-days" method would result in the approval of a greater number of days credit per claim, you may, within the said fifteen day period, submit assessment work breakdowns listing the employees names, addresses and the dates and hours they worked. The new work breakdowns should be submitted direct to the Lands Management Branch, Toronto. The report will be re assessed and a new statement of credits based on actual days worked will be issued.
