Banro (NYSE: BAA) jumped 13% yesterday after the company announced that it had finally completed its bankable feasibility study on its Twangiza project and proved up nearly 4 mln ounces of its 10 mln ounce resource. Thus, we can now calculate an NAV for BAA.

BAA has no debt. So, assuming $1,000 gold, 3.67 mln ounces of Proven & Probable reserves, an average cash cost of $429 per ounce over the life of the mine (which is based on the feasibility study), and the estimated $410 mln required for cap ex, we get an NAV of almost $15 a share (which gives zero value to the company's current cash balance of around $20 mln and its remaining 5.6 mln ounce resource at Twangiza, not to mention the resource estimates at its other properties).

Among companies reporting quarterly earnings on Thursday were Safeway Stores Inc. (NYSE: SWY), the largest food retailer in North America, and Newmont Mining Corp. (NYSE: NEM), one of the world's largest gold producers.

Despite ongoing efforts to upgrade the image of its stores, Safeway, which reported that fourth-quarter earnings in-line with the consensus estimates of analysts surveyed by Thomson Financial, also reported that same-store sales slowed.

The quarterly earnings came to $301.1 million, or 68 cents per share, for the period that ended December 29, down 2% from $307.9 million, or 69 cents per share, in the same quarter of 2006, when tax benefits lifted results. Excluding that gain, earnings per share would have climbed by more than 11%. Fourth-quarter revenue rose 7% to $13.36 billion, which beat the analysts' average estimates.

Despite signs of a slowdown, the fourth quarter capped Safeway's most profitable year since 2001. The company earned $888.4 million, or $1.99 per share, on sales of $42.3 billion, compared to earnings of $870.6 million, or $1.94 per share, on revenue of $40.2 billion in 2006. For 2008, Safeway forecast earnings of $2.25 to $2.35 per share, in-line with analysts' expectations.

Safeway shares fell more than $3 in morning trading, reaching a new 52-week low of $28.80.

Yesterday, gold was up over $23 in trading, hitting a seven month high. A CPI report of 2.7% helped send gold flying.

The concern is that with energy and home prices having declined since the spring of 2006, that the CPI would be close to zero or even negative by now. Yesterday's data show there is still plenty of liquidity in the economy to keep it going and rate decreases are going to be pushed out for a while. The possibility of an increase or two exists if growth ticks up a bit too much.

We blogged in October about the merits of investing in Newmont Mining (NYSE: NEM). Our rationale was the huge correction in its stock price and the discount it sold for relative to the value of its gold reserves. The value of its gold reserves are estimated to be 20% to 50% higher than its stock price.

Newmont reports earnings today, not that it really matters since it trades relative to the price of gold price. But it would be worth a listen.

There are a number of factors which favor the outlook for gold. Most countries have floating currencies or have their currencies backed by floating currencies. Central banking mistakes will lead to higher levels of inflation -- and we know that central banks will make mistakes.

Newmont is a good hedge in a world of floating currencies and awash with cash.
