Full Description of Material Change
 
 
5.1  Full Description of Material Change
 
Pretivm reported the remaining assay results from underground exploration drilling in the Valley of the Kings.  These results include 8 intersections grading greater than 1,000 grams per tonne gold uncut from 6,164 meters of drilling in 46 holes. (See Table 1 below for assays.)
 
Selected drill highlights include:
 
•Hole VU-365 intersected 328.91 grams of gold per tonne uncut over 20.50 meters, including 13,400 grams of gold per tonne uncut over 0.50 meters;
•Hole VU-369 intersected 96.71 grams of gold per tonne uncut over 44.95 meters, including 7,700 grams of gold per tonne uncut over 0.50 meters;
•Hole VU-384 intersected 331.99 grams of gold per tonne uncut over 8.00 meters, including 5,210 grams of gold per tonne uncut over 0.50 meters;
•Hole VU-390 intersected 179.14 grams of gold per tonne uncut over 13.50 meters, including 4,780 grams of gold per tonne uncut over 0.50 meters;
•Hole VU-397 intersected 175.44 grams of gold per tonne uncut over 10.78 meters, including 3,770 grams of gold per tonne uncut over 0.50 meters;
•Hole VU-385 intersected 1,200 grams of gold per tonne uncut over 0.50 meters;
•Hole VU-383 intersected 1,095 grams of gold per tonne uncut over 0.50 meters;
•Hole VU-391 intersected 1,040 grams of gold per tonne uncut over 0.50 meters.

  The bonanza-grade gold intercepts noted above were encountered in drilling to the east and west, as well as above and below the area of the Valley of the Kings Bulk Sample Program (the “Program”).
 
Underground exploration drilling has expanded the defined Valley of the Kings high-grade gold mineralization to the east, and mineralization remains open in all directions.
 
For plan views of the reported drilling please see attached Schedule A.
 
In 2013 a total of 38,830 meters of underground drilling was completed in the Valley of the Kings, comprising 16,789 meters of Program drilling and 22,041 meters of exploration drilling.  Assay results from 2013 drilling include a total of 69 intercepts grading over 1,000 grams per tonne gold uncut (of which 15 were in the Cleopatra Vein).
 
For a summary table of Valley of the Kings assay results by grade interval please see attached Schedule A.
 
Processing of the approximately 1,500 wet tonnes of bulk sample material remaining from the Program is expected to be completed during the first week of December, with final results reported after the completion of assaying.
 
The results both from the 38,830 meters of underground drilling and from milling will be incorporated into

(1)
True thickness to be determined.
 
(2)
Unless otherwise indicated as uncut, all gold assays over 430 g/t were cut to 430 g/t.
 
(3)
All samples were submitted for preparation and analysis by ALS Chemex at its facilities in Terrace, B.C. All samples were analyzed using multi-digestion with ICP finish and fire assay with AA finish for gold. Samples over 100 ppm silver were reanalyzed using four acid digestion with an ore grade AA finish. Samples over 1,500 ppm silver were fire assayed with a gravimetric finish. Samples with over 10 ppm gold were fire assayed with a gravimetric finish. One in 20 samples was blank, one in 20 was a standard sample, and differing one in 20 samples was a field duplicate one-quarter split core assayed at ALS Chemex in Vancouver, B.C.
 
(4)
Hole ended in mineralization.
