Sample Preparation Analyses and Security
Sampling conducted in 2009 and 2010 was at a reconnaissance level constituting grab and composite chip samples of outcrop. Standard geo-referencing was employed by hand held GPS recording of UTM co-ordinates. Field sample sites were identified by normal procedures involving tagging the sites with respective sample number codification. All sites were highlighted with flagging tape, both at the ground outcrop level and at eye-level. The composite chip samples were typically centimetre-size shards, while grab samples were centimetre-decimeter chunks of rusty and/or sheared rock or individual quartz veins. All samples were bagged, identified by inserted assay ticket numbers and tape sealed. Samples were transported from the field site by the authorized field geologist and delivered in person to AGAT Laboratories, 2054 Kingsway Road, Sudbury, Ontario. During the period, a total of 103-samples were submitted for analysis.
All of the samples were submitted to AGAT Laboratories for analysis. Their data quality assurance and control protocol is documented below. This information is available on the company website.

Documented Procedures – All aspects of the Quality Assurance System are documented. This includes analytical methodologies, safety, environmental and management systems. This documentation is critical to the training of personnel and for demonstrating the Quality Assurance System to clients and accrediting bodies. By completing the work according to the best practices, the precision, accuracy and reliability of all services are enhanced.”
All of the samples were analysed for gold employing fire assay preparation and ICP-OES determination for gold content. A metals package provided AGAT Laboratories for 44-elements using an Agua-Regia digestion and elemental determination by ICP-OES was also performed on each sample.
The following is a verbatim description of the sample preparation and approach as supplied by AGAT labs for the samples submitted in 2009 and 2010.
Screening and Drying: “Samples are dried at 60o C followed by screening passing 80-mesh. The minus fraction is used for analysis and the pulp fraction is stored as reject material.
“Fire Assay-ICP-OES Finish: “The pulverized sample is weighed and mixed with a fluxing agent. The flux assists in melting and helps fuse the sample at a reasonable temperature and promotes separation of the gangue (waste) material from the precious metals. Every assay fusion should show two products, a lead button and, above it, a glassy slag. The lead button should be bright. Soft and malleable and should separate from the slag.
Cupels with the lead buttons are placed in a cupellation furnace and heated leaving only a silver dore bead that represents the entire precious metal content of the original sample. This bead was then analyzed using a PerkinElmer 7300DV-ICPOES (Inductively Coupled Plasma-Optical Emission Spectroscopy). A reference blank is fused every 40 samples (or once per fire assay batch), a standard reference material is weighed at least every 20 samples or once per fire assay set and replicates are fused 12 samples or once per fire assay set. This sample is chosen at random and weighed and fused in replicate (replicate meaning a second subsample taken from the pulp envelope).
“Aqua Regia Digest-ICP-OES Finish: “Aqua Regia is commonly used in the digestion of certain geological samples and is effective for most base metal sulphates, sulphides, oxides and carbonates. It is noted that aqua regia only provides a partial digestion for most rock forming elements and elements of a refractory nature. Aqua Regia is a digestion using 3:1 hot mixture of hydrochloric and nitric acid for a predetermined time. The resultant product is diluted with deionized water. An aliquot is measured using a using a PerkinElmer 7300DV-ICPOES (Inductively Coupled Plasma-Optical Emission Spectroscopy) for 44 elements. A reference blank is fused every 40 samples (or once per fire assay batch), a standard reference material is weighed at least every 20 samples or once per fire assay set and replicates are fused 12 samples or once per fire assay set. This sample is chosen at random and weighed and fused in replicate (replicate meaning a second subsample taken from the pulp envelope).”
The MMI soil survey was performed by Dan Patrie Explorations Inc. and overall supervised by Don Hawke, P.Geo, of Precambrian Ventures Ltd. A standard sample collection protocol as defined by All applicable safety, environmental and legal regulations and guidelines;
SGS Labs was followed. Each sample site was geo-referenced by GPS to UTM co-ordinate system. All samples were collected from 15-25 cm below the Ao horizon at intervals of 30-meters on lines spaced 100-meters oriented in a general northeast – southwest direction, effectively perpendicular to the regional geologic trend, and duplicates were taken at intervals of 25-samples. 24-traverse lines were run that averaged 1,600-meters in length. Five partial lines, 650-meters long resulted in a gap of no sampling 890-meters long by 440-meters wide located immediately southwest of Kitz Lake. The reason for this sample gap was extremely wet ground conditions encountered in the late fall season of 2011.
After the samples were bagged in the field and delivered to the office of Dan Patrie Explorations Inc., located in Massey, Ontario, Don Hawke, P.Geo, tagged the samples and employed a local trucking firm to deliver the samples to SGS Labs in Toronto, Ontario. Arrival of the samples at the lab was confirmed to Don Hawke by both the trucking firm and the lab.
The nature of grab samples and to a certain extent composite chip samples, do not lend themselves for field duplication of the sampled material. The inherent bias of such samples usually toward “visually promising” material means that field duplication is difficult to achieve unless the mineralized body is homogenously mineralized throughout. Grab samples are collected to obtain generalized information usually of mineralized material.
Nevertheless, data verification is accomplished by AGAT Laboratories themselves. The lab scrutinizes its analytical procedures with a system of internal blind and double blind samples that conform to the International Organization for Standardization’s ISO/IEC 17025, "General Requirements for the Competence of Testing and Calibration Laboratories' and the ISO 9000 series of Quality Management standards.
Prior to undertaking of the MMI soil survey a one-line orientation survey was conducted along a line that incorporated a fence of diamond drilling that included M139, M152 and M165 located within the Feather River zone. This line was chosen because M152 and M162 intersected >1.0 gpt au values at shallow depths. AuRR and AsRR values from this survey correlate with the zone as defined by these drill holes successfully validating the relevance of the MMI technique as an exploration methodology applicable to the Feather River-BayView property.
Besides the field personnel including duplicates every 25th-sample into the sample stream, SGS Labs employs its own in-house quality control/quality assurance protocols routinely to all of their sampling methodologies. SGS Minerals Services is an accredited (Standards Council of Canada and Conforms with requirements of CAN-P-1579, CAN-P-4E (ISO/IEC 17025:2005)) full service laboratory located in Canada at Toronto and Vancouver and is licensed by Wamtech PTY, Australia to exclusively perform Wamtech’s MMI process.
No issues or discrepancies have been reported by the SGS lab regarding the results, nor have the authors of this report been altered by the supervisory personnel that oversaw the MMI survey of any concerns regarding the collection of the samples or the data generated by the survey.
