Oil Shale Mining

Utah, Wyoming, Saskatchewan

The announcement of a strategic environmental assessment in Quebec led Questerre to pursue unconventional oil opportunities. In the fall of 2011, the Company assembled a portfolio of oil shale mining opportunities including prospective acreage and licensing rights to a proprietary technology to produce oil from shale.

The EcoShale process is designed to extract high quality light oil from mined oil shale in an environmentally sustainable manner. The process involves the mining of shale that is placed in a large clay lined and covered capsule. Expendable heat pipe loops are strategically placed in the capsule with the oil shale. External blowers are used to force the hot flue gas from natural gas burners through the pipe loops to heat the oil shale. Collection pipes are located at the top and bottom of the capsule to recover the natural gas and oil respectively. Produced natural gas from heating the oil shale fuels the burners used to heat other capsules. Upon completion, the pipes in the capsule are sealed and the surface of the capsule is covered with top soil and seeded with native vegetation.

To capture additional resources, Questerre also executed a ten year non-exclusive option agreement to license Red Leaf's EcoShale processes and technology for any project identified by Questerre. Subject to the project meeting the criteria for commerciality, Questerre will pay Red Leaf a fee of US$2 million for each licence issued. Red Leaf will receive a gross overriding royalty on the project on mutually acceptable terms.

To assess its own acreage prospective for oil shale in the Pasquia Hills area of east central Saskatchewan, Questerre conducted a 16 well core-hole program during the year. Approximately 30m to 45m of good quality shale was encountered in all the wells drilled with grades of 10 g/t to 20 g/t and select intervals of up to 16 g/t to 20 g/t within a 20m to 30m section. Based on the core data,the original 100,000 acres has been high-graded to approximately 39,000 net acres.

For 2013, Questerre plans to complete analysis of the core data in advance of developing an independent resource assessment.

EcoShale™ In-Capsule Technology

[ http://www.redleafinc.com/index.php?opt ... 6&Itemid=4 ]

Red Leaf Resources, Inc. has developed the EcoShale™ In-Capsule Technology to economically and environmentally produce high quality liquid transportation fuels from oil shale, oil sands, coal, lignite and bio-mass.

The EcoShale™ In-Capsule Technology involves heating mined shale in a closed surface impoundment, or capsule. The process relies on conventional mining and construction methods and produces a bottomless oil product that requires no coking. The process produces a shale oil with a much higher concentration of middle distillate than West Texas intermediate crude. Two synthetic shale oil products are produced: (1) prompt oil of approximately 29 API gravity; (2) condensate oil of approximately 39 API gravity. The oil and condensate produced with this process have no fines and have very low acid numbers.

The technology requires no process water, protects groundwater and vegetation, uses low temperatures for heating and allows for rapid site reclamation.

The resultant product is a high quality feedstock with an average 34 API and no fines. The process also results in synthetic natural gas production allowing for energy self-sufficiency.

Questerre Testing Oil Shale in Saskatchewan

Wed, 9 May, 2012

Questerre Energy Corporation ("Questerre" or the "Company") reported today that it has recently completed the first phase of a core hole program to assess its oil shale licenses in Saskatchewan.

The winter program was designed to evaluate the western block, known as the Arborfield block, covering 58,112 net acres. During the first quarter of 2012, over 700m of continuous core was obtained from 10 new wells. The wells were drilled to an average depth of 100m with wireline logs acquired from surface to depth. Good core was recovered throughout the Second White Specks shale, the primary formation of interest. Approximately 30m of the target oil shale formation was encountered in all the wells drilled.

Approximately 400 core samples from these wells are currently being analyzed for geochemical properties. Testing will also include modified Fisher assay analysis to evaluate the potential oil yield and an assessment of the prospective oil shale resource. Questerre is currently permitting a summer program of up to 10 additional wells. These wells will gather core data to evaluate the eastern block, known as the Wildcat Hills block, covering an additional 42,572 net acres.

The Company's 100,684 net acres in east central Saskatchewan overlies a well documented oil shale deposit. The Company is primarily targeting the Second White Specks formation on this acreage. The coring program is designed to assess prospective oil shale resource and potential for the application of oil shale mining technology.

Questerre Energy Corporation is an independent energy company focused on non-conventional oil and gas resources. The Company is currently developing a portfolio of oil shale assets in North America. It is also securing a social license to commercialize its Utica natural gas discovery in Quebec. The Company is underpinned by light oil assets and a strong balance sheet. Questerre is committed to the economic development of its resources in an environmentally conscious and socially responsible manner.

Core program indicates Saskatchewan oil shale potential

[ http://www.ogj.com/articles/2013/11/cor ... ntial.html ]

HOUSTON, Nov. 19 11/19/2013 By OGJ editors

Questerre Energy Corp., Calgary, said results from the second core hole program on its oil shale acreage at Pasquia Hills in east-central Saskatchewan exceeded expectations.

The results confirm that the acreage overlies a well-established oil shale deposit, and the company said it plans to commission an independent resource assessment early next year. Questerre said it will use Red Leaf’s EcoShale process to convert the resources into reserves.

Red Leaf is securing final permits and should begin work in the field for the first commercial scale capsule this December, Questerre added.

The six-well core program was completed in fall 2012 on the eastern block of Questerre’s acreage. Questerre recovered 653 m of good quality core and ran a full suite of logs over the target Second White Specs shale.

All the wells drilled encountered the target formation with a minimum thickness of 26 m and a maximum of 59 m. The first 10 wells on the western block recovered a combined total of more than 30 m of core.

Preliminary results of modified Fischer assay conducted by an independent laboratory on 180 m of core samples indicates grades of 10-17 gal/ton with select intervals from some wells averaging 15-18 gal/ton in an interval of up to 10 m and individual samples of over 26 gal/ton. Another independent laboratory will verify the results.
