CALGARY, ALBERTA–(Marketwired – April 11, 2017) – Canacol Energy Ltd. (“Canacol” or the “Corporation“) (TSX:CNE)(OTCQX:CNNEF)(BVC:CNEC) is pleased to report on the conventional natural gas prospective resources (resources other than reserves, ROTR) for its Esperanza, VIM-21, VIM-5, and VIM-19 exploration blocks in the Lower Magdalena valley basin of Colombia. Prospective resources are based on a new independent resources audit prepared by Gaffney, Cline & Associates (“GCA“), effective December 31, 2016 (the “GCA Report“).

Canacol Energy Ltd Gross Prospective Resources Summary

Charle Gamba, President and CEO of Canacol, commented “The Corporation has achieved significant conventional natural gas exploration and development drilling success across its substantial acreage position in the Lower Magdalena valley basin over the past 3 years. Mark Teare, Canacol’s Senior Vice President of Exploration will comment about our large inventory of conventional natural gas opportunities, and the Corporation’s recent engagement of GCA to prepare an independent audit of the prospective resources of the inventory plays, prospects and leads.”

Mr. Teare said “GCA’s independent prospective resources audit evaluated and estimated conventional natural gas prospective resources for 47 individual prospects and leads, which Canacol has aggregated to an unrisked mean of 2 trillion standard cubic feet or a risked mean of 482 billion standard cubic feet. The estimated prospective resources underline the significant potential of Canacol’s exploration blocks located in the Lower Magdalena valley basin of northern Colombia. Using state of the art 3D seismic acquisition and processing technology, our subsurface G&G technical team has developed techniques to high-grade prospects that may be gas charged in the Oligocene aged Cienaga de Oro Formation (“CDO”) thereby reducing the geological risk associated with drilling of the prospects.

In addition, recent exploration drilling success at the Nelson 6 exploration well has opened up a new shallow gas play in the Miocene aged Porquero Formation (“Porquero”), which our subsurface G&G team is currently investigating further across our blocks. With an established prospect and lead inventory that contains multiple exploration drilling targets in the CDO, and a new gas exploration fairway proven in the shallow Porquero sandstone reservoir, we anticipate being very busy exploring our blocks in the foreseeable future.”

Third Party Independent Audit for Conventional Natural Gas Prospective Resources (Resources Other Than Reserves, ROTR)

The following discussion is subject to a number of cautionary statements, assumptions and risks as set forth therein. See “Information Regarding Disclosure on Oil and Gas Resources and Operational Information” at the end of this release for additional cautionary language, explanations and discussion, and see “Forward-looking Statements” for a statement of principal assumptions and risks that may apply. See also “Definitions” in this press release. The discussion includes reference to prospective resources as per the GCA Report, which was prepared in accordance with the COGE Handbook.

GCA was commissioned to conduct an independent prospective resources audit of Canacol’s internal estimates of prospective resources for the Corporation’s 100% Working Interest position in the Esperanza, VIM-21, VIM-5, and VIM-19 exploration blocks in the Lower Magdalena valley basin (the “Audited Areas“) effective December 31, 2016. All references in the following discussion to prospective resources are in reference to conventional natural gas in the Audited Areas included in the GCA Report.

On an unrisked and risked basis, the following table represents an aggregation of gross prospective resources and associated after royalty before tax expected monetary value for identified plays, leads and prospects (1, 2, 3) on the four exploration blocks.

Cautionary Statement:

1. There is no certainty that any portion of the resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the resources.
2. An estimate of expected monetary value of future net revenue of prospective resources is preliminary in nature and is provided to assist the reader in reaching an opinion on the merit and likelihood of the Corporation proceeding with the required investment. It includes prospective resources that are considered too uncertain with respect to the chance of discovery and chance of development to be classified as reserves. There is uncertainty that the expected monetary value of future net revenue will be realized.

Table Notes

The representation of prospective resources in the GCA report reflects the resource potential of the Corporation’s 100% working interest land position (785,000 acres) in the Lower Magdalena valley basin. Of primary importance is the resource potential of the CDO comprised of up to 5000 feet of deltaic and marginal marine sandstones and shales. The CDO play is characterized by structural features such as faulted horst blocks and faulted three-way dip anticlinal closures. Specific prospects are identified and mapped using 3D seismic, and technical risk is further mitigated by the application of seismic attribute analysis to investigate the presence of gas-charged sandstones. The Corporation has enjoyed significant success in both its exploration and development drilling program with the CDO play, with 5 out of 6 exploration wells encountering gas (83% GCoS), and 4 out of 4 development wells encountering gas.

The Corporation is committed to investigate new plays in addition to the CDO play to mitigate exploration risk. Of particular interest are the turbiditic sandstone reservoirs of the shallow Porquero. The new Porquero play is typically characterized by faulted, three-way dip anticlinal closures, but may also have a stratigraphic component. Porquero exploration prospects are identified and mapped using 3D seismic, and technical risk is further mitigated by the application of seismic attribute analysis to investigate the presence of gas-charged sandstones. Recent exploration success at Nelson 6 has successfully demonstrated the effectiveness of the seismic attribute analysis and confirmed the commerciality of the shallow Porquero play. Work in progress on recently reprocessed 3D seismic data has identified additional potential for the Porquero play.

For both the CDO and the Porquero plays, and based upon the representation of prospective resources in the GCA Report, management expects that significant additional resources will be developed in the future with continued drilling success on currently undeveloped blocks. The significant factors that may change the prospective resources estimates include the outcome of further exploration and delineation drilling, which may change the estimates either positively or negatively, future technology improvements, which would positively affect the estimates, additional processing capacity that could positively affect the volumes recovered e.g. additional compression, and the requirement to meet regulatory contractual commitments to acquire seismic and drill exploratory wells to retain acreage.

In accordance to the six considerations for Commerciality outlined in COGE Handbook Volume 2 Section 2.4.4, GCA represents risked prospective resources as a function of the Chance of Development (CoD) of any future discovery. Estimating CoD requires that the related development project be commercial such that the commerciality conditions of regulatory approval for facilities, flow lines and access to markets are met. All prospects and leads fall within 50 km of the Corporation’s central processing facility at Jobo that may be easily expanded as required. The Corporation has successfully secured sales contracts for its existing production, and is confident of its ability to secure future contracts in an expanding market both along the Caribbean coast and inland Colombia. To achieve its current production levels for natural gas in northern Colombia, the Corporation has demonstrated its ability to manage other contingencies such as legal, regulatory, political, social license, internal and external approvals and access to project finance to ensure the timely execution of its exploration and field development plans in the future. Appropriate levels of capital investment are anticipated to ensure future full field development including drilling, tie-in, infrastructure buildout for facilities and flowlines, and abandonment and reclamation. The Corporation has prepared a realistic schedule for the execution of its proposed exploration drilling campaign over the next three years along with additional time scheduled for follow-up development drilling, installation of flow-lines, and plant expansion as required. Future field development will be for conventional natural gas. There is no expectation of HPHT (High Pressure High Temperature) reservoirs in the Lower Magdalena valley basin. Any discovery will be developed using existing industry technology with standard gas completions in the well-bores, and standard surface treatment and compression facilities in a same manner as the seven operated fields presently under production (Nelson, Palmer, Clarinete, Oboe, Ariana, Canaflecha, and Katana).

Definitions

Resource definitions, including those set out below, are as specified by NI 51-101, including by reference to CSA Staff Notice 51-324 – Glossary to NI 51-101 Standards of Disclosure for Oil and Gas Activities and the COGE Handbook.

“Resources” are quantities of petroleum that are estimated to exist originally in naturally occurring accumulations, including the quantity of petroleum that is estimated, as of a given date, to be contained in known accumulations, prior to production, plus those estimated quantities in accumulations yet to be discovered.

“Prospective Resources” are defined as those quantities of petroleum estimated, on a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. Contingencies may include factors such as economic, legal, environmental, political and regulatory matters or a lack of markets.

As used in this press release, “BCF” means billion standard cubic feet.

The above prospective resources volumes under the heading “un-risked” have not been adjusted for the Chance of Discovery and the Chance of Development, while the prospective resources volumes under the heading “risked” have been risk discounted for the GCA’s estimates of Chance of Discovery (Geological Chance of Success (GCoS)) and Chance of Development (CoD) which involves assessing various risks based upon a number of assumptions and other factors. The Chance of Development is the probability that a resource, once it has been discovered, will ultimately be commercially developed. While the Corporation believes that such estimates and underlying assumptions are reasonable, many of these assumptions are beyond the Corporation’s control, are subject to change and may not, over time, prove to be accurate. As a result, the actual level of various risks (including those currently identified and that may be identified in the future) could prove to be greater and the Chance of Development lower than currently estimated. Such differences could be material.

The estimates of prospective resources provided in this press release are estimates only and there is no guarantee that the estimated prospective resources will be recovered. Actual prospective resources may be greater than or less than the estimates provided in this press release and the differences may be material. There is no certainty that any portion of the prospective resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the prospective resources.

Estimates of prospective resources are by their nature more speculative than estimates of proved reserves and would require substantial capital spending over a significant number of years to implement recovery. Actual locations drilled and quantities that may be ultimately recovered from our properties will differ substantially. In addition, we have made no commitment to drill, and likely will not drill, all of the drilling locations that have been attributable to these quantities.

The following classification of prospective resources represented probabilistically as used in this press release:

• Low Estimate means there is at least a 90 percent probability (P90) that the quantities actually recovered will equal or exceed the low estimate.
• Best Estimate means there is at least a 50 percent probability (P50) that the quantities actually recovered will equal or exceed the best estimate.
• High Estimate means there is at least a 10 percent probability (P10) that the quantities actually recovered will equal or exceed the high estimate.
• Mean Estimate represents the arithmetic average of the expected recoverable volume. It is the most accurate single point representation of the volume distribution.
