Ernest C. Schlotter, a senior analyst with Zurich, Switzerland-based SISM Research and a four star analyst according to StarMine, has issued an update on TAMM Oil and Gas Inc. (OTCBB: TAMO) in a four-page report dated December 24, 2012, which includes an overview and asset valuation on its ownership it holds through the Joint Venture agreement with CEC North Star Ltd based in Calgary, Canada. During 2012 Tamm Oil and Gas signed a binding agreement to become a JV-partner of CEC North Star Energy Ltd.; shareholder voting is scheduled for the next AGM in 2013. Tamm Oil agreed to vend into CEC its substantial Oilsands leases adjacent to North Star’s major core leases. CEC North Star Energy holds a portfolio of assets of one hundred percent working interest containing conventional light sweet oil developments, and unconventional long-term heavy oil assets with blue-sky potential of several billions of barrels exploration and developments. Its unconventional carbonate assets hold great promises for the future. After examining the Tamm Oil and Gas development Ernst Schlotter of SISM Research concluded that: “[SISM] view(s) this JV-agreement as very positive for Tamm Oil shareholders, as through this transaction the Company receives a 25%+ ownership in three distinct projects with three different models for development and to take advantage of changes in current technology and economic sensitivities. In addition Tamm Oil benefits from a highly experienced management thus reducing the development’s operating costs significantly. At current market capitalization, Tamm Oil is valued at only $0.014/barrel significantly below our calculated prospective average price of $0.1583/barrel and therefore the company is significantly undervalued.” When asked about Tamm’s growth in value to shareholders Mr.Schlotter stated, “We have conclusively calculated a fair market price of $1.35 for Tamm shares bearing in mind the stock price has the potential to double to $2.70 in 2013 when the planned exploration work is successfully executed.”Source: A complimentary copy of the report, which includes important disclosures, disclaimers and analyst’s qualifications, is available for download via the SISM Website at: http://sism.com/Tamm%20Oil%20Research%20December%2024,%202012%20Final.pdf The full report includes all important disclosures, disclaimer, and analyst information.
