VANCOUVER, Sept. 9 /CNW/ - Logan Resources Ltd. (TSXV:LGR) ("Logan" or
the "Company") is pleased to announce that it has received an initial
NI 43-101 compliant resource estimate and preliminary economic assessment for
its 100% owned Brynnor Iron Deposit on Vancouver Island. The report was
prepared by Peter George, B.Sc., P.Geo., of Geoex Limited. Mr. George (the
"Author") is a Qualified Person as defined in NI 43-101 and has over 40 years
experience in the mining industry, including extensive experience in
estimation of mineral resources and economic evaluations. Much of this news
release is taken directly from the report. Highlights of the report include:
- Measured plus indicated mineral resources of 7,070,000 tonnes grading
51.3% iron containing 5,750,000 tonnes of iron concentrate grading
- Inferred mineral resources of 18,620,000 tonnes grading 51.3% iron
containing 15,140,000 tonnes of iron concentrate grading 63.7%.
- The Author concludes that the property has economic potential,
subject to feasibility study capital and operating cost estimates
that confirm that the measured and indicated resources can be
categorized as proven and probable reserves.
- The Property is located 3 km south of the Alberni-Tofino Highway
(Highway 4) and is accessible by a well-maintained, all-season gravel
road that is used for logging and tourist access to Toquart Inlet.
The boat-loading site used by Noranda during mining operations in the
1960's is on Toquart Inlet, 12 road-kilometres south of the Deposit.
Power and water is readily available in the area.
- The Author concludes that the Brynnor deposit warrants additional
work that will bring it to the production decision stage. The Author
concludes that that the Preliminary Economic Assessment that has been
completed as part of the report indicates significant economic
potential for the Brynnor underground resource and recommends that a
feasibility-level estimate of capital and operating costs be prepared
as a basis for upgrading measured and indicated resources to proven
and probable reserves and for a more accurate financial evaluation.
- The Author recommends that a surface drilling program be undertaken
to upgrade a portion of the current inferred resources to indicated
resources. Twenty proposed holes totalling approximately 6,200 metres
would test the mineralization down dip from the bottom of the current
measured and indicated resource as well as along strike to the east
of the measured and indicated resource for a distance of 200 metres.
- The estimated cost of the proposed feasibility study and drilling is
The Brynnor Iron Deposit was discovered in 1960 and acquired in the
spring of 1960 by Noranda Mines ("Noranda"). Twenty thousand feet of surface
drilling (6,100 metres) were completed and indicated a near-surface magnetite
ore body containing approximately 5,000,000 short tons (4.54 million metric
tonnes) with an average grade of 51% iron. In January 1961 Noranda entered
into a contract with a consortium of Japanese steel mills to deliver
700,000 short tons (635,000 metric tonnes) per year of magnetite concentrates
for a seven-year term.
Development commenced in May 1961 and the first shipment of ore was made
on May 30, 1962. In a one-year period Noranda prepared an open pit for mining
and constructed a crushing, concentrating and boat loading facility capable of
producing 700,000 tonnes of magnetite concentrate per year. Total capital
costs were $11 million, excluding the subsequent underground development.
Based upon US Consumer Price Index inflation factors, the 1960 capital costs
would be equivalent to approximately $77 million 2008 dollars.
Ongoing surface drilling in 1961-62 to the east of the open pit indicated
a more steeply dipping, slightly deeper, fault offset extension of the open
pit mineralization. In 1964 Noranda completed a 3-compartment shaft to a depth
of 856 feet and established stations on the 400-, 600-, and 750-foot levels,
with a 200,000 gallon water sump and two 1000 gallon per hour pumps on the
750 foot level. A total of 6,450 feet of drifts and crosscuts and 1,002 feet
of raises were completed. Some stopes were developed, however other than
development muck, no mining of underground ore was completed (Hancock 1988).
A 7-month strike from July 1966 to March 1967 stopped production. After
the strike, open pit operations continued until the end of 1968 and
concentrator operations were shut down on completion of milling of stockpiled
Noranda removed all infrastructure and capped the shaft. The mining
claims and mining permit lapsed and the current claim 404313 that covers the
Deposit was staked by the Company in August 2004.
The Author relied upon data available in the B.C. Energy, Mines and
Petroleum Resources assessment and library files in Victoria, British
Columbia. The essential data relating to the history of the Deposit is based
upon work by Noranda Mines Limited in the 1960's. In the Author's opinion it
is appropriate to accept this work at face value as it was prepared by
experienced Canadian mining professionals that would certainly be considered
qualified persons pursuant to current NI-43-101 regulations. The historic
underground cross sections used for the mineral resource estimates in this
Report were for year-end 1967 and were signed and sealed by a Noranda
The Author has relied upon the capital and operating cost guidelines
published by the American Institute of Mining Engineers (O'Hare and Soboleski
1992). In the Author's opinion these estimation methods are suitable for
purposes of completing preliminary assessments of the economic potential of
mineral deposits. The Author has used these guidelines since they were
initially introduced by O'Hare in 1980 and has found them to provide cost
estimates that are similar to full feasibility study estimates where operating
and capital costs for such projects have been made public.
The Author did a mineral resource estimate for the open pit resource that
was mined in the 1960's in order to establish a methodology to estimate the
grade and tonnage of the mineral resources in the underground portion of the
Brynnor deposit. A reconciliation of the Author's open pit resource estimate
with the production records for the operational years of the 1960's verifies
that the methodology used in estimation of the underground resource are valid.
The Author used industry standard resource estimation methods in the
preparation of the resource estimate. North-south drill sections were created
on 30.48-metre (100-feet) centres for the open pit mineralization and on
15.24-metre (50-feet) centres for the underground mineralization.
Interpretation of the hole-to-hole correlation of mineralization was
completed, polygons were established around drill hole intercepts, areas
(m(2)) were established for each polygon, and volumes (m(3)) were determined
based on the distance between the sections. Polygon tonnages were calculated
by applying a specific gravity factor based on the ratio of magnetite to host
rock in the polygon. Polygon grades were calculated based on the ratio of
magnetite to host rock in the polygon.
The following table summarizes the Geoex resource estimates:
Resource Category Resource Grade Concentrate Grade
Tonnes % Iron tonnes % Iron
Measured 4,990,000 52.5% 4,110,000 63.7%
Indicated 2,090,000 48.5% 1,640,000 63.7%
Measured plus Indicated 7,070,000 51.3% 5,750,000 63.7%
Inferred 18,620,000 51.3% 15,140,000 63.7%
Resource criteria used are as follows:
Measured Resources In areas that have been drilled and where underground
workings have delineated continuity of the mineralization as interpreted on
drill sections, the Author is of the opinion that all resources can be
categorized as Measured Resources. The maximum spacing between drill sections
is 30.48 metres (100 feet) so the maximum lateral (east-west) area of
influence is 15.48 metres from the plane of the section.
Indicated Resources have been estimated based upon extending measured
resource blocks down dip for the same vertical distance or horizontal distance
as the vertical height of the immediately adjacent measured resource block, or
half way to an adjacent hole that does not contain mineralization, whichever
is the lesser distance.
Inferred Resources down dip have been estimated based upon the tonnes per
vertical metre of measured plus indicated resources being projected vertically
for a distance equivalent to the average vertical height of the measured plus
indicated resource. Similarly lateral (east-west) inferred resources have been
estimated based upon the tonnes per lateral metre of measured plus indicated
resources being projected laterally for a distance equal to the lateral
dimensions of the measured plus indicated resource.
The Brynnor mineralization consists of massive magnetite hosted in
metasomatic skarn alteration zones within limestones and calcareous tuffs of
the Late Triassic Quatsino Formation in areas where the sedimentary rocks are
in the contact zone of Middle Jurassic granodiorite and diorite batholithic
intrusions. The measured and indicated resource has a strike length of
240 metres, a down-dip extent of 200 metres, an average true width of
approximately 35 metres, and an average specific gravity of 4.0. The resource
is open along strike to the east and west and down-dip.
Based on a Preliminary Economic Assessment with a ten-year mine life, the
Author concludes that the Property has economic potential, subject to
feasibility study capital and operating cost estimates that confirm that the
measured and indicated resources can be categorized as proven and probable
The Preliminary Economic Assessment is preliminary in nature as the
operating costs and capital costs are based upon generalized estimates. The
first eight years of production are based upon Measured and Indicated
Resources however, the last two years are based upon Inferred Resources that
are considered too speculative geologically to have economic considerations
applied to them that would allow them to be categorized as mineral reserves
and thus there is no certainty that the preliminary assessment will be fully
No dilution was applied to the resources and it is assumed that mining
recovery of the resource is 90% and plant recovery of the magnetite is 95%.
The cashflow projections are based upon constant 2008 dollars and no
discounting was used in determining payback.
Total life-of-mine capital costs are estimated to be approximately
$100 million excluding working capital. Operating costs are estimated to be
$43.15 per tonne of iron concentrate or $24.45 per tonne of ore mined.
A base case iron price of US$ 131.65 per tonne is assumed based upon
published international 2008 seaborne iron concentrate prices (Rio Tinto
$2.067 per mtu or $131.65 for 63.7% iron concentrate). Recent opinions by
knowledgeable analysts suggest that future iron concentrate prices should
continue to increase, particularly for high grade, high quality magnetite
concentrate of the type that the Deposit historically produced.
At $131.65 per tonne of iron concentrate grading 63.7% iron, payback will
be achieved in 2 years from start of production or 4 years from start of the
underground development program. Operational breakeven iron concentrate price
is $45 per tonne and breakeven iron concentrate price for recovery of capital
is $75 per tonne. The after tax internal rate of return is 35% and net present
value at 5% and 10% discount rates is $136 million and $86 million
respectively. Total tax burden was assumed to be 35% per year. Total earnings
before income tax, depletion and amortization are $347 million ($40 million
If operating costs are increased by 25% to $30.45 per ton of ore mined,
payback will be achieved in 2.5 years from start of production or 4.5 years
from start of the underground development program. Operational breakeven iron
concentrate price is $55 per tonne and breakeven iron concentrate price for
recovery of capital is $65 per tonne.
If life-of-mine capital costs are increased by 25% to approximately
$125 million, payback will be achieved in 2.5 years from start of production
or 4.5 years from start of the underground development program. Operational
breakeven iron concentrate price is $55 per tonne and breakeven iron
concentrate price for recovery of capital is $70 per tonne.
If both capital costs and operating costs are increased by 25%, payback
will be achieved in 3 years from start of production or 5 years from start of
the underground development program. Operational breakeven iron concentrate
price is $55 per tonne and breakeven iron concentrate price for recovery of
capital is $80 per tonne.
A minimum 8-year mine life is projected based on measured and indicated
resources. Conversion of the inferred resources to measured and indicated
resources would provide an additional 20 years of mine life.
