Drilling
Since no diamond core drilling has been done since 1992 on the Mount Washington Property,
relevant details of all drilling have been included in the History section of this report. No
attempt has been made by the author to tabulate or verify total numbers of holes or total
metres drilled, particularly since details of most of the pre-production definition percussion and
diamond drilling by Mt. Washington Copper during the early 1960’s is not available. All other
operators used exclusively diamond drilling, and since the early 1980’s all operators used
primarily NQ size drill core, but earlier operators generally used smaller diameter drill core.
Generally, drilling of the flat-lying tabular zones and veins at the Mount Washington Copper
North and South Pits and at the Lakeview-Domineer Zone was done using vertical or steeply
inclined drill holes, and core angles of mineralized structures were generally recorded in the
drill logs. Therefore, drill intercepts for these zones and veins are generally close to true
thicknesses, confirmed in the underground adits and in the exposures in the open pits. In the
sulphidic breccia zones in the Oyster Breccia and Murex Breccia areas, these mineralized zones
have not been sufficiently drilled to establish their shapes and orientations, and therefore the
relationships between drill intercepts and true thickness for these zones are unknown.
Sample Preparation, Analyses and Security
During the time period that extensive exploration work was conducted on the Mount
Washington Property, it appears that industry standard methods were used for sample quality
control, preparation, analyses and security by the operators undertaking the work. All field
work was supervised by qualified and experienced professional geoscientists, who would have
been able to identify unexpected discrepancies between sampled media and analytical results
obtained from them. Although the use of blind analytical blanks and standards may have been
employed on a few programs, it was neither a common practice nor routine procedure at the
time the exploration work was done. In most cases, independent commercial analytical
laboratories were used by the operators to prepare and analyses samples, and some
certificates of analyses from those laboratories are available in ARIS reports for some the
exploration programs. However, the larger integrated exploration and mining companies such
as Cominco and Noranda operated and utilized in-house analytical laboratories to process
samples from at least some of their exploration programs. Although the author cannot certify

any of the historical work, there is no reason to doubt the adequacy of sample preparation,
security and analytical procedures related to sampling on the Mount Washington Property
during its exploration history.
The most recent work conducted by the author utilized commercial laboratories for all
geochemical analyses and was conducted using industry-standard chain of custody procedures
with all samples. Due to the preliminary nature of the field geochemistry programs, no blind
analytical blanks and standards were utilized by the author; and only the internal procedures
employed by the commercial laboratories were utilized for QA/QC protocols.
Data Verification
At the time that exploration work was conducted in the Mount Washington Property area, it
appears that industry standard methods were used for quality control and data verification.
Although the author cannot verify any of the historical work, there is no reason to doubt the
adequacy of quality control measures and data verification procedures related to sampling
during the exploration history of the area, and the Property.
In addition to the work completed in 2013, 2016, 2018 and 2019 and described in the
Exploration section, the author visited some of the mineralized exposures on the Mt.
Washington property on four occasions between 2000 and 2005 as per the Introduction section
of this report, with highlights summarized as follows:
September 14, 2000
The author visited the Mount Washington Property area as Regional Geologist for the B.C.
Ministry of Energy and Mines, accompanied by District Manager Greg Carriere, P.Eng., and Cliff
Rennie, P.Eng., President of Better Resources Ltd. Visits were made to the Lakeview-Domineer
adit portal, the Domineer adits, and the Mt. Washington Copper North and South pits. The
author took six selected grab samples, from which reference pieces were cut by the author and
microscopically analyzed, and the remaining samples sent by the author to Acme Analytical
Laboratories where they were crushed, pulverized and analyzed for multi-elements using
induced coupled plasma (ICP) methods. The descriptions and analytical results were reported
