I've been having a BRUTAL time logging into Agoracom for the last two days. This morning I was on long enough to get this post written then Agoracom pooched the post. About two hrs of work and notes poof - gone. (luckily I save a copy before hitting send). Anyone else having trouble?

Regarding the new RE document:

RE on Sedar: http://sedar.com/CheckCode.do;jsessionid=0000LY0tS9seZ87YlkAV6YDxVZP:-1

I don't pretend to understand a lot of it but there are a few tidbits that stood out to me. My bold and underlines.

DDH 422 was stopped due to an avalanche. So drilling was stopped artificially (by natural causes lol). That means that it might be possible that 2012 drilling was able to continue that core from where it left off (unless the hole was damaged or blocked). If we can continue the hole, we could be seeing deeper results sooner than if we'd started from the surface

Pg 83: Hole 2011CF422 was drilled approximately 1,500 m northwest of the Paramount Zone, and tested a geophysical anomaly from the Quantec 2011 Titan 24 IP and MT survey. Although this hole was not completed to the target depth due to avalanching, it did return an intercept of 0.146% copper, 0.06 g/t gold, 0.01% molybdenum and 1.0 g/t silver over a core interval of 235 m from 83 to 318 m. This hole represents the discovery of a new zone of mineralization at Schaft Creek and lends support to the interpretation that the other untested chargeability anomalies could represent additional zones of mineralization (press release April 20, 2012).

  • On page 85 there is a discussion of core recovery and assay results. It seems that the grades of our more rubbly cores are typically understated by about 14 to 18%. 25% of our cores could be affected. This was identified last year but I am not clear as to whether this info was incorporated into the RE. If it isn't factored in, the realized grades are going to be materially impacted to the positive imho.

Drill core recovery data from portions of the legacy drill campaigns are available. For the Hecla and Teck drill campaigns staff measured core lengths and calculated RQD at site. For the Copper Fox drill campaigns, Copper Fox staff have recorded core lengths and calculated core recoveries and RQD at the sites of the drill holes. Core recoveries have generally averaged more than 90%.

AMEC reviewed the core recovery data and found a trend of decreasing grade with decreasing core recovery. A similar trend is present when separating the core recovery data out by program by previous project operators.

There is a risk of approximately 25% of the assays having negatively-biased copper, gold and molybdenum grades due to low core recoveries.

These observations made by Kulla et al. (2011) are displayed in Table 10.11.

Table 10.11 Core Recovery Statistics

Element 90-100% Recovery <90% Recovery Difference

Count Mean Count Mean (%)

Cu (%) 17,148 0.223 5,718 0.190 -14.5%

Au (g/t) 11,145 0.181 3,407 0.150 -17.2%

Mo (%) 17,088 0.013 5,750 0.011 -17.7.%

  • On page 189 is the list of recommendations. This is somewhat similar to the exploration NR we got earlier this spring: Titan , drill Mike/ES/GK anomallies, and..

..."Continue drilling into the Discovery Zone, situated approximately 1,200 m northwest of the deposit, as a follow-up to mineralization encountered in drillhole 2011CF422. While a considerable amount of drilling is required to delineate and determine the significance of this discovery, the continuity of the mineralization and its location on the western edge of a large strong chargeability anomaly suggests this zone could host significant mineralization."

But a couple ofadditional recommendations stick out: infill drilling of Paramount to move resources from the Inferred to the Indicated, more drilling around 2011DDH's 423 & 424 near DDHAS-16, and more drilling on the west side of the West Breccia Zone (Paramount).

Phase 2 of the exploration programme ($1.4M estimated cost) suggests 10 drills. They seem to be still interested in that area around DDHAS 16.

Section 9.4.3 on page 52 says that there is as many as 31 targets to explore (Low, medium, and high priority).

Page 54 shows the little bit of the missing Titan survey of the GK zone.
