The most recent work undertaken on the Feather River-BayView property was by Precambrian Ventures in 2009, 2010 and Kitrinor in 2011. The work involved reconnaissance level prospecting sampling and GPS geo-referencing items such as historical sample sites, showings and diamond drill collars and an MMI soil survey.
In the period from 2009 to 2010, 103-grab and composite chip samples were collected and submitted to AGAT Laboratories for gold and multi-element analysis. Grab and chip samples collected from the Feather River zone, 30-meters southeast of DDH M160, returned anomalous values ranging from 126 ppb to 569 ppb, (see Table 9).

The Mile Out showing was initially identified as a result of a soil survey from which a gold value of 2,870 ppb Au, (Bergman 1985) was obtained. The results of the survey ultimately outlined an area 500-meters long and 150-meters wide. From this area, a grab sample, (260108A) returned a value of 1,200 ppb (Precambrian Ventures, 2011) Au from a sheared mafic volcanic. This area is interpreted to lie within the Mishibishu Deformation Zone.
Six of the seven historic drill hole collars, established in the diamond drill campaign conducted by Granges Exploration in 1987, in the Feather River zone, were located. From this information and historical plans, an accurate geo-referenced drill lay-out of the drill collars was able to be constructed.
Structural data recordings revealed a significant change in the foliation direction of the altered schist in the Mishibishu Deformation Zone in the vicinity of the Feather River zone. A noticeable change in strike of 0700 west of Schist Creek, to 1200-1300 between Schist Creek and Feather River and then to a strike of 1500-1700 east of Feather River indicate a possible fold with a northeast axis. Dip directions are all steep to the north and minor folds plunge moderately to steeply to the east. The best gold mineralization encountered in the drilling appears to have occurred in proximity to this flexure.
Since March 2011, Kitrinor has incurred geoscience expenditures of $150,133 on the Feather River-BayView property within the Feather River portion. $105,133 of these expenditures are directly allocated to having completed a Mobile Metal Ion soil survey. A total of 1,279 soil samples were collected 15-20cm below the Ao horizon at 30-meter spacing along 100-meter spaced traverse lines.
The Mobile Metal ion geochemical technique extracts the loosely bound metal ions on soil particles that are released from mineralized sources. The advantages of this technique as claimed by SGS are:
A. few false anomalies
B. focused, sharp anomalies
C. excellent repeatability
D. definition of metal zones and associations
E. detection of deeply buried mineralization
F. low noise
G. low limit of detection.

Analysis of the sample material included a seven element profile consisting of Au, Ag, As, Cu, Pb, Zn and Co. From the assay data response ratios were calculated by dividing the absolute value of the sample by the calculated background for each element. Response ratios of 2X to 10X background were considered to be somewhat significant based on their correlation with other data/features. Response rations of greater than 10X background were considered to be very significant. Histograms of Bin maxima were generated for each element response ratio and the colour coded bin ranges were plotted on the sample location points. The points were contoured based on their colour index for interpretation.
MMI Survey Results
This anomalous area consists of three Au cluster zones with a weak Ag association that correlates with the Schist Creek and Feather River showings.
This anomalous area is located proximal, within 200-meters southwest, to the Mile Out showing. AuRR, (gold response ratio), AgRR (silver response ratio), AsRR (arsenic response ratio) and CoRR (cobalt response ratio) correlate with each other over an area measuring 350-meters long in a NW-SE direction (i.e. parallel to regional geological trends) by 80-meter wide.
This anomaly occurs 550-meters east-northeast of the Mile Out showing. Two AuRR clusters form a zone in area 265-meters long (NW-SE) by 255-meters wide that one of which is open to the southeast. AgRR clustering is associated with this anomaly.
