lithium price has doubled in 2015, so number in this articleshould be 2x value: from stockwatch tonite Marcy Kiesman's Durango Resources Inc. (DGO), up one-half cent to four cents on 1.39 million shares, has received an "unsolicited joint venture proposal" for its NMX East lithium project in northern Quebec. (The name and directional qualifier come from a nearby advanced lithium project, Whabouchi, being worked by Guy Bourassa's Nemaska Lithium Inc. (NMX: $0.40).) Durango apparently staked the first claims that make up the NMX East project either late in 2014 or early in 2015. Ms. Kiesman was surprisingly mum about the matter until last fall, when she not so quietly began adding additional blocks of ground to the northwest and west of Nemaska's project. Durango now holds 1,200 hectares of claims bordering Whabouchi. At last report Whabouchi held 28 million tonnes measured and indicated at 1.57 per cent lithium oxide and another 4.7 million inferred at 1.51 per cent. A 2014 feasibility study credited a 26-year mine with a discounted net present value of $581-million after taxes, but the capital cost was a hefty $522-million 384543. Raising that sum will be a daunting challenge for Mr. Bourassa.
