INTRODUCTION
a)
History of Property
The area now covered by the Alco claims was originally
staked as the Bear-Doe group of claims.
In 1975, during construction of the Burrell Creek logging
road, a weakly mineralized stockwork of copper and molybendite was
explored in the Nelson granodiorite over an intermittent northsouth strike length of 700 metres.
The area was staked by J. Nedokus,
who subsequently optioned these claims to Rio Tinto Canadian Explorations Ltd.
This company ran geological, geochemical and geophysical
surveys over the area in 1976 and their option has since been cancelled.
The Alco claim was retained by J. Nedokus and P. Koochin and was sub-
sequently optioned to Brenda Mines Ltd. in the spring of 1980. Alco 4
and Alco 5 claims were staked in May, 1980.
b)
Vegetation and Topography
The topography of the claim area between Burrell and Nicoll
Creeks consists of steep sided, mound shaped hills.
The land rises
steeply, west and east of these two creeks.
Vegetation at lower elevations is variable, consisting €or
the most part of grassy hills with sparse vegetation.
Some hillsides
are covered by dense growths of jackpine.. Steep slopes to the east
of Nicoll Creek are covered by dense growths of cedar and jackpine
windfalls.
West of Burrell Creek, vegetation is sparse on steep slopes.

PROPERTY DESCRIPTION
a)
Location and Access
The Alco mineral property is situated approximately 50
kilometers north of Grand Forks, B.C., immediately south of the
junction of Burrell Creek and Franklin Creek.
Access is via a paved road following the Granby River
northwards from Grand Forks, and then onto the gravel topped
Burrell Creek logging road.
The property straddles this road
between the 18 km and 20 km logging signs.

REGIONAL SETTING
Structurally, the area of the Alco claims is part of the
Cariboo geanticline, a stable massif
adjoining the Quesnel trough
to the west.
The area has been mapped by the G.S.C.
by Drysdale (1915).

DIAMOND DRILLING
a)
Introduction
Maitland Explorations Ltd. was contracted to drill
approximately 305 metres (1,000 feet) of BQ core (35 mm) during
June, 1981.
Four holes were drilled (a total of 313 metres) to test
the extent of surface mineralization.
All holes were drilled to
the west of Nicoll Creek, between lines 15+00 N and 22+00 N.
b)
Lithologies
1) Granodiorite
Granodiorite was the dominant rock type in all four drill
holes.
This unit is a mottled gray to grayish-green, medium grained
rock composed of quartz, feldspar, biotite and hornblende in a hypidiomorphic texture.
The dominant alteration type is phyllic (quartz, sericite
and pyrite) , although prophylitic alteration (chlorite and epidote)
is also widespread.
Phyllic alteration is often accompanied by
chlorite, which may represent a transitional phyllic/prophylitic
alteration type.
2)
Granite Porphyry
This rock was encountered in two of the drill holes.
It
ranges from gray to reddish-gray and is commonly fine grained.
In
some instances grain size becomes so fine the rock is best described
as a rhyolite.
This is particularly apparent near the margins of
- 6 -
the dike where a chill zone has formed.
Phenocrysts are composed of hornblende and pottasium
feldspar.
3)
Andesite and Andesite Porphyry
Found in two holes, this rock is a dark grayish-green,
massive dike which locally may contain granite fragments, imparting
a brecciated texture.
When a porphyritic texture is present, pheno-
crysts are composed of hornblende.
4)
Serpentine
This unit was found in only one drill hole.

c)

It is off
3 cm fragments of quartz.
Mineralization
Mineralization, with the exception of pyrite, is exclus-
ively fracture controlled.
Molybdenite and chalcopyrite occur along
fractures and slips of several different orientations.
Bornite has
been found, but is uncommon.

Diamond Drill Hole Descriptions
1) D.D.H. No. A-81-1
Location: 21+75 N, 3+60 W
Azimuth: 45O
Dip: -45O
Total Depth: 96 metres (315 feet)
Hole A-81-1 was drilled approximately 125 metres west of
the Burrell Creek logging road and contained the strongest mineralization.
- 7 -
Granodiorite was the dominant rock type and was locally strongly
altered.
Where phyllic alteration was found, it was commonly
accompanied by epidote and/or chlorite.
Two dikes, a granite
porphyry and an andesite porphyry occurred in the second half of
the hole, where mineralization had decreased considerably.
2)
D.D.H. No. A-81-2
Azimuth: 45O
Dip: -45O
Total Depth: 59 metres (194 feet)
The second hole was drilled to the east of the Burrell
Creek road.
Granodiorite was the only rock type and both mineral-
ization and alteration (dominantly phyllic) were weak.
3)
D.D.H. No. A-81-3
Azimuth: 45O
Dip: -45O
Total Depth: 93 metres ( 3 0 5 feet)
Granodiorite and granite porphyry were the predominate
lithology.
Alteration was both phyllic and prophylitic, ranging
from weak to moderate.

Granodiorite and andesite were the only lithologies.
Although alteration was locally strong (phyllic), mineralization
was very poor.
V
CONCLUSIONS
Based on diamond drill results, mineralization on the Alco
property has little continuity and occurs only within sporatic
fracture sets.
Only drill hole No. 1 produced encouraging, but
low grade results; the remainder of the holes drilled were largely
barren.
No further work on this property is recommended.
