Large Low Grade Gold Deposits

Potentially highly leveraged to dramatic increases in Gold prices, though similarly leveraged to the downside.
Low grade deposits are expensive to mine as more tonnes of rock are processed to extract the gold driving high initial capital costs to build infrastructure to process large ore volumes and high energy costs for volume of mining and processing.

These deposits are potentially just  "geochemical anomalies", as Brent Cook might describe them, rather than economically mineable deposits.

A large number of these deposits, which may appear very very cheap on a $/oz basis, are also remote with enormous infrastructure requirements, beyond the immediate mine, to make them viable.
Further risk comes with jurisdiction; making enormous capital investments requires long minelife and stability of political regime, taxation etc.

If high gold prices come about due to currency devaluation, and if this similarly spikes high oil prices and cost push inflation or hyper-inflation, there is a risk that these deposits will remain uneconomic due to the amount of energy required to mine them. The Gold:Oil ratio would be a key indicator.
If however currencies and debt are to be devalued against gold whilst controlling energy costs to sustain economic growth and recovery then these will be incredibly rich deposits, at which point the key concern becomes jurisdiction, "windfall profits" and taxation.

Many of these deposits occur with base metals, in particular Copper, so both copper and gold prices will drive economic potential.
Newletter writer John Kaiser has taken an interest in a number of the low market cap deposits and there are public "trackers" on his site which give a lot more details to follow up to date.

The fact that so many of these projects, especially the lower cap companies, with potentially large projects, remain at low valuations implies a number of possibilites;
a) That the market does not believe continued high gold and especially copper prices will be sustained, perhaps seeing a hard landing in China.
b) Equally it alerts us to the difficulty of raising project finance which will see enormous dilution of current shareholders in raising funds to complete asset build-out.

Availability of funds & liquidity could change dramatically if QE / LTRO continues to expand Central Bank credit lines and takes hold through bank lending and monetary devaluation, with a possible "commodity wars - scramble for assets" described by Jesse.

The acquisition of Equinox by Barrick for $7.6bn seems to point to a different view of copper's future. Against Barrick's $50bn market cap this is a big non-gold bet.
"Dr Copper" itself has shown a strong price base at $3/lb during the October 2011 bottom.

There follows some brief review of the companies involved, a stock watchlist and maps etc.
Companies and their Projects
  • Osisko (OSK.TO) - Canada - in production (Acquired by Yamana & Agnico Eagle) 
  • Brett Resources - Acquired by Osisko - even lower grade.
  • Terrane Metals - Canada BC , Mr Milligan, Copper Gold project acquired by Thompson Creek Metals. (TCM.TO). Current build seeing cost over-runs, part of the fear around these deposits. Projected production early 2014, success here could prove economics for these large low grade deposits. See Progress presentation here.

  • Pretium Resources (PVG.TO) - Bob Quartermain - Realistically has become a high grade story at Brucejack/Valley of the Kings but also have Snowfield low grade. Strong stock through 2011 correction. Potentially in production on high grade with leverage and ability to progress low grade. Quartermain built silver Standard, may develop exploration and growth company. Would Snowfield and Seabridge's KSM deposit be developed together?

    • Presentation
    • The excitement is being cased by the high grade Brucejack / Valley of the Kings discovery : 
      • 5m oz indicated @ 17g/t. Inferred 10m oz @25g/t
    • There is Large low grade deposit at Snowfield. 35m oz M&I+inferred @ low grade.
    • Silver Standard (SSO.TO) own 22% - @ 20-4-11 - PVG $1.3bn mkt cap, SSO Mkt Cap $1.1bn

Major miners e.g. Xstrata and other majors operate in the Philippines, certain areas see political unrest. Recent announcement on progress to feasability and permitting has moved the shareprice
  • Crazy Horse (CZH.v) - Another Philippines Copper-Gold project. The "Gold Miner Pulse" site has a daily tracked "fair valuation" blog. Recent PEA study shows NPV $500m for an initial $500m capex, on $1000 gold / $3 copper. At $1400 gold and $4 copper NPV is $1.1-$1.7bn depending on scale. Chairman has moved onto be President of Sabina so credible people? ** Majority of production is from Copper.

  3. carpathian gold i think has the biggest bang for the buck.

  4. Gold in pyrite chalcopyrite and galena. Gold and silver floatation concentrate leaching
