Topley Richfield Project

Shamrock Enterprises Inc. has signed an Option Agreement to acquire from two private vendors, a 100% interest in the Topley-Richfield gold/copper/silver/lead/zinc project (The Project) located in the Bulkley Valley, 100 km southeast of Smithers, B.C. The Topely-Richfield Project consists of seven of contiguous mineral claims covering an area of 2,313 hectares. The Project hosts a number of old mine workings, shafts, trenches and drilling and has a reported “historic” reserves of 170,000 tonnes grading 3.5 g/t gold and 161 g/t silver (Ref B.C. AR# 17374, Esso Minerals of Canada, April 1988). The property is accessible year round via highways and Holmes Creek Forest Service Road which provides the best access for heavy equipment to the Property. The Bulkley Valley is a prolific mining district within the Skeena Arch. Past and present mining projects within 100 km. of the Project include the Bell, Granisle, Huckleberry, Endako, Dome and Equity Silver mines. Work programs can be carried out year round.

Exploration During 2006-2008

The exploration programs carried out during this time period was the most comprehensive and included more ‘modern’ techniques such as 3D modelling and GPS surveying. Soil geochemical sampling and IP survey was conducted over an area of roughly 2km wide x 3km long (Figure 1) thus surveying 1.5km from the main area of work (1975-1987) to the east and 1.5km north of the most northerly RC holes completed by Esso Minerals.

Results from the soil geochemical sampling show a number of significant copper and silver anomalies occurring in areas underlain by overburden at ~ 20 to 60m deep. During the 2017 GIS review a number of plan maps were generated plotting soil geochemical results with magnetic and IP (chargeability/resistivity) contours. The plotted results clearly show three significant soil Cu and Ag anomalies completely separate from and at variable distances from the main showing area. Also of note is a number of anomalous Cu and Ag values occur at edge of the sampling area suggesting these areas are open. A brief description of each anomaly follows with corresponding magnetic and resistivity map figures (Figure 2, 3 and 4) outlining copper anomalies (Ag are highly similar and not included) inserted below the descriptions;

Anomaly A: This occurs west and northwest of the main showing roughly 500 x 1000m in area with a northerly trend underlain by broad northwest trending resistivity lows with corresponding low to moderate chargeability. Magnetics at this location is somewhat complicated but is underlain mostly by magnetic high. However at the southwest edge of the anomaly is a well-defined circular mag low completely within a mag high. This would suggest a possible intrusion 350m across.

Anomaly B: Located at the western edge of the soil grid it is > 1km long trending north. Two things to note is that it is open to the west associated with a strong magnetic low similar to but much larger than that associated with the main showing and a 100m wide circular moderate mag high occurring in the middle of the anomaly. The anomaly may also be open to the west.

Anomaly C: On the eastern edge of the soil grid the soil anomaly is underlain by a north trending sinuous resistivity high with the north half associated with a magnetic high. The ‘East Vein’ occurs within this anomaly and suggests that this may represent a more quartz rich zone when compared with the main showing and the mag high reflecting sulphide mineralization not masked by carbonate alteration. Which seems to be the case at the main showing hosted within quartz-carbonate alteration.

As can be seen from the magnetic map overall the east of the grid is mostly underlain by a magnetic high and the west half is a magnetic low but interestingly the main showing in the southeast is hosted within an arcuate low splitting the magnetic high. The strongest part of the west half of the magnetic low may underlying Anomaly B is very similar to that of that main showing and may represent an extension of the alteration and/or structure hosting the known mineralization.
