Pretium update: disappointing grades

(*Disclosure:  Pretium is by far my largest short position so I am biased.  Take what I say with a grain of salt and do your own homework.)

The production figures reported in Pretium’s MD&A filed on August 10, 2017 fall far short of the projections from Pretium’s latest published feasibility study.

According to the feasibility study filed on June 30 2014 (effective date June 19, 2014), year 1 production from Pretium’s flagship project would have a head grade of 15.4 g/t gold with a recovery of 96.8%.  The effective grade after recovery losses would be 14.9072 g/t gold.

Figures are from Table 17.2 of the technical report.

Compare this with the data from page 2 of the MD&A:

  • For June, 8510 ounces of gold were produced and 70805 tonnes of ore were processed.  8510 / 70805 X 28.3495 gram/ounce = 3.407 g/t for June
  • For July, 16882 ounces of gold were produced and 83667 tones of ore were processed.  16882 / 83667 X 28.3495 gram/ounce = 5.720 g/t for July
  • An average of 4.660 g/t for June and July

The 3.407 g/t and 5.720 g/t fall far short of hitting the 14.907 g/t mark projected from Pretium’s feasibility study three years ago.

While grades so far have been low relative to the estimates from the feasibility study, Pretium does expect grades to ramp up [page 4; emphasis mine]:

Working Capital

As the Brucejack Mine continues to ramp-up grade, we expect the increased production and concomitant proceeds from the sale of doré and flotation concentrate will enable us to overcome our short-term working capital deficit. We expect as gold production ramps up this deficit will reverse (refer to the “Liquidity and Capital Resources” section below). In addition, we are evaluating other opportunities to bolster our short-term working capital.
