Cleantech Transit Inc. (CLNO)

Cleantech Transit Inc. was founded to capitalize on technology advances and manufacturing opportunities in the growing clean energy public transportation sector. The Company has expanded its focus to invest directly in specific green projects that could maximize shareholder value. Recognizing the many economic and operational advances of converting wood waste into renewable sources of energy, Cleantech Transit Inc. has selected to invest in Phoenix Energy (www.phoenixenergy.net).

In the developed world biomass is becoming more important for dual applications such as heat and power generation. Biomass is a clean renewable energy resource derived from the waste of various human and natural activities. It excludes organic material which has been transformed by geological processes into substances such as coal or petroleum.

The energy of biomass is extracted from three distinct sources:
o Wood is the largest energy source of biomass: contributors include the timber industry, agricultural crops and raw materials from the forest.
o Waste energy is the second largest source of biomass energy. The main contributors are: municipal solid waste and manufacturing waste.
o Alcohol fuels is the third largest contributor and is derived mainly from corn.

Using biomass power replaces the need to burn use coal to generate electricity. Additionally, the use of biomass power also reduces the need for oil to mine and deliver coal to far off power stations, thereby significantly reducing greenhouse gas emissions. Most surprisingly, using wood waste as fuel is actually more beneficial to the environment than allowing it to decompose naturally, because of the elimination of methane during combustion.

Cleantech Transit, Inc.(CLNO) is pleased to announce it has met its funding requirement to secure the Company's ability to earn in 25% of the 500KW Merced Project.

The Company is in the final stages of closing its initial interest in the Merced Project and is currently working on completing the necessary documentation and expects closing the transaction approximately June 30th. As previously announced Cleantech has the option to earn up to 40% of the Merced Project and the Company plans to continue to work towards increasing its interest in the Merced Project as they move ahead.

Orofino Gold Corp. (ORFG)

Orofino Gold Corp. (ORFG) is a Colombia based gold producer founded as a private company in 2009 by former executives with over 50 cumulative years in mining exploration, finance, and development expertise.

Orofino Gold Corp. (ORFG) objective is to continue to build shareholder value through the exploration and development of Senderos de Oro and additional accretive acquisitions, capitalizing on the extensive experience and relationships that management has developed over the past 25 years.

However you look at it, gold is a valuable thing. The ancient Egyptians revered it and used it well, fashioning countless antiques, decorations, and masks from gold in order to celebrate their royalty and religion. Gold is used to commemorate weddings, used as a sign of ultimate affection for young men who want to win the hearts of their potential wives.

With gold so valuable, some people tend to wonder - well, if it's so valuable, why do we use it in our teeth? As it turns out, one of the reasons gold is so valuable in the first place is because of its durability and flexibility as a metal - it has a wide array of uses, and one of them happens to be dentistry.

Gold is more useful than other metals which were mined from Earth. Its significance is derived from a diversity of special properties. Gold conducts electricity, does not tarnish, is very easy to work, can be drawn into wire, can be hammered into thin sheets, alloys with many other metals, can be melted and cast into highly detailed shapes, has a wonderful color and a brilliant luster. Gold is a memorable metal that occupies a special place in the human mind.

One of gold's significant properties is psychological. Most people readily associate gold's distinctive color with wealth, and many even consider the color beautiful - possibly because it is so closely associated with money. This gives it an immeasurable advantage over other tangible and portable stores of wealth.

The jewelry trade is a permanent and global marketing initiative for bullion, and has for thousands of years gone hand in hand with un-worked metal in promoting gold as a store of material value. It creates a significant barrier to entry for any rival material and contributes to the security of gold, in bullion form, as a form of money.

Orofino Gold Corp. recently announced that it has requested Sepro Systems Corp. to assist in the design criteria to improve environmental sensitivity and maximize yield production and recoveries as it begins development at its Culo Alzado mine site in Sur de Bolivar, Colombia.

Canadian-based Sepro Systems Corp. is a leading supplier of state-of-the-art, environmentally sensitive mineral processing equipment for projects worldwide.

Recent permitting issues for Colombian based Gold projects due to environmental concerns from the Colombian government have made sustainable and environmentally conscious mining programs a top priority for many of the region's mining companies. Orofino's directors and management feel taking steps to ensure sustainability from the beginning of its exploration process is part of the company's responsibility to the local population and government. These steps will also better position the company for long-term development of its concessions thanks to a decreased environmental impact.

In addition to positioning Orofino for environmentally sustainable growth, installing Sepro equipment at its Culo Alzado mine site will also dramatically improve recoveries of minerals from current workings. Orofino intends to install new, state-of-the-art crushing, milling, and recovery systems in order to begin a regular sampling program as laid-out by the company's Qualified Person as described in the National Instrument 43-101. This equipment will enable Orofino to generate regular, up-to-date metallurgical and geological reports, improving knowledge of the composition of the producing concessions and increasing investor confidence.
