THUNDER BAY, ONTARIO–(Marketwired – May 26, 2015) – Source Exploration Corp. (the "Company" or "Source") (TSX VENTURE:SOP)(4QW.F) is pleased to announce additional step-out drilling results from the El Dorado / Juan Bran zone at its Las Minas property. These results continue to expand the down-dip and strike extensions with strong grades and widths within the zone. Additionally, infill drilling at the Santa Cruz target returned a 90.1 metre interval of gold, silver and copper mineralization grading 1.73 g/t Au Eq(1) and containing high-grade intercepts, including3.57 g/t Au Eq over 20 metres and 2.46 g/t Au Eq over 30 metres.

Highlights from El Dorado/ Juan Bran & Santa Cruz Drilling:

LM-15-ED-23

• 2.63 g/t Au Eq across 10.0 metres, within
• 1.83 g/t Au Eq over 17.0 metres

LM- 15-ED-24

• 4.74 g/t Au Eq across 19.7 metres, within
• 3.59 g/t Au Eq over 27.7 metres

LM-15-JB-09

• 2.24 g/t Au Eq across 6.0 metres

LM-15-SC-17

• 3.57 g/t Au Eq across 20.0 metres, and separately
• 2.46 g/t Au Eq across 30.0 metres, within
• 1.73 g/t Au Eq over 90.1 metres.

Composite Assays for these holes are included in Table 1 below.

Brian Robertson, President & CEO, commented: "The recent drilling continues to expand the mineralized zones at the El Dorado/ Juan Bran and Santa Cruz targets. The widely spaced step-out holes were drilled with no misses, with the drilling widths and grades continuing to surprise to the upside. The width of the zones and the number of high-grade intercepts are indicative of a potentially large and well mineralized system."

El Dorado/ Juan Bran Drilling

Drilling at the El Dorado/Juan Bran target has outlined a mineralized footprint measuring from 170 metres to 420 metres wide, with drill intercepts varying from 6.0 to 82.0 metres in thickness. The zone has been drill outlined 650 metres down-dip and remains open both to depth and on-strike.

Hole LM-15-ED-24 was drilled as a step-out hole located 80 metres south of previously reported hole LM-15-ED-21, which assayed 4.01 g/t Au Eq over 14.0 metres – see Press release dated May 7, 2015. The hole intersected 19.7 metres of mineralization assaying 4.74 g/t Au Eq. The high-grade interval was contained within 27.7 metres grading 3.59 g/t Au Eq.

Hole LM-15-ED-23 was located 120 metres further to the south of hole LM-15-ED-24. Gold, silver and copper mineralization grading 1.83 g/t Au EQ was intersected from 90.6 to 107.7, totaling 17.0 metres. The intercept contained a higher grade interval of 10.0 metres assaying 2.63 g/t Au Eq.

Hole LM-15-JB-09 was collared 140 metres to the west of hole LM-15-ED-24 to test the width of the southern extension of the zone. The hole cut 6.0 metres of exoskarn and retrograde endoskarnassaying 2.24 g/t Au Eq, contained within 8.0 metres grading 1.73 g/t Au Eq. The mineralized zone was cut off by a late feldspar porphyry dyke.

Santa Cruz Drilling Results

Diamond drill hole LM- 15-SC-17 was drilled as an infill hole to confirm the thickness and orientation of the high-grade Santa Cruz 1-3 zone. It intersected 90.1 metres of mineralization extending from near surface and assaying 1.73 g/t Au Eq. The wider intercept contained a high-grade 30.0 metre interval from 22.2 to 52.2 metres grading 2.46 g/t Au Eq as well as a 20 metre intercept from 74.2 to 94.2 metres assaying 3.57 g/t Au Eq.

A total of 16 diamond drill holes were drilled in the 2015 drill program to drill test the Eldorado/ Juan Bran ( 6 holes), Santa Cruz (7 holes) and Nopaltepec (3 holes) targets. Assay results are pending for an additional five holes and will be reported when received from the laboratory. Please refer to the Company's press releases dated March 17, 2015, April 29, 2015 and May 7, 2015 for previously-reported results of the 2015 drill program.

All reported intervals referred to in this news release are core lengths and additional information is required to determine true widths. Assays are uncut, length – weighted average values.

Samples containing free metallic gold mineralization were assayed by SGS Mineral Services at Durango, Mexico, an accredited and independent laboratory, using the FAS30K-Au metallic screen fire assay method.

About Las Minas

The Las Minas Project hosts near-surface gold – silver and copper skarn mineralization and high-grade gold – silver epithermal vein deposits. The project is comprised of six mineral concessions covering approximately 1,616 hectares (3,995 acres), with several small scale, past-producing mines and a number of untested targets.

The district is host to one of the largest under explored gold – silver copper skarn systems known in Mexico, and has a production history that extends back to the Aztec era. The Las Minas granodiorite intrusive measures approximately 10 kilometres in diameter and underlies the Las Minas concessions. The mineralization controls and association with magnetite appear to be similar to the Guerrero Gold belt, which is the site of the Los Filos and Morelos gold deposits.

Las Minas is an early-stage exploration project and does not contain any mineral resource estimates as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). The potential quantities and grades disclosed herein are conceptual in nature, and there has been insufficient exploration to define a mineral resource for the targets discussed herein. It is uncertain if further exploration will result in these targets being delineated as a mineral resource.

Quality Assurance/Quality Control

The technical information in this news release has been reviewed and approved by Sonny Bernales, P. Geo., a registered Professional Geoscientist in the Province of British Columbia and a qualified person as defined by NI 43-101. Mr. Bernales is responsible for logistics and supervision of all exploration activity conducted by Source on the property.

The Company has implemented and adheres to a strict Quality Assurance/Quality Control program which includes inserting mineralized standards and blanks into the sample stream, about 1 for every 10 samples. The standards and blanks were obtained from CDN Resource Laboratories Ltd. of Langley, BC, Canada. Each sample bag is properly sealed and kept in a secured, restricted storage place prior to shipping to the lab. Samples are shipped directly by Source or picked-up by the lab vehicle with chain of custody/sample submittal signed and dated. The Company sends it samples to SGS Mineral Services (ISO/IEC 17025) at Durango, Mexico, an accredited and independent laboratory. Check samples are also sent to ALS-Chemex Laboratories in North Vancouver, Canada.
