Tiger Gold Corp. (TSX-V: TIGR) (FSE: D150) (OTCQB: TGRGF) is pleased to report assay results from its Ceibal target in Colombia’s prolific Mid-Cauca gold belt. Tiger’s initial 5,000-metre drill program at Ceibal forms part of Tiger’s ongoing 20,000-metre drill program at its Quinchía Gold Project.

Highlights:

• CEDDH-010 intersected predominantly porphyry-style mineralization over a 685.7 m near-surface interval, including two broad intervals separated by a 34.45 m dike:
  • 214 m at 0.7 g/t Au from 22 m downhole
    • including 23 m at 1.1 g/t Au
    • including 8 m at 1.0 g/t Au

• • 437.05 m at 0.5 g/t Au from 271 m downhole
    • including 9 m at 2.2 g/t Au
    • including 10 m at 1.4 g/t Au

• Hole ended in mineralization at 707.7 m downhole, approximately 600 m below surface, and remains open at depth
• Three drill rigs remain active across the project, with assays pending from Ceibal, Dos Quebradas, and Tesorito

“CEDDH-010 delivers another strong result for Ceibal and extends the scale of mineralization along our first section line,” commented Robert Vallis, President and CEO. “Drilled as a step-back of the CEDDH-001 discovery hole, CEDDH-010 intersected predominantly porphyry-style mineralization over a 686-metre interval beginning near surface, with the hole ending in mineralization. Ceibal remains open along its apparent strike and to depth, and the balance of our initial program is primarily focused on step-out drilling to the northwest and southeast. Drilling results to date at Ceibal are being used to inform the detailed planning of a follow-up drill program in support of a maiden Mineral Resource estimate.”

The results reported in this news release are summarized in Tables 1 and 2. Figures 1 and 2 show the drillhole collar and section locations. Figure 3 is a regional map of the Quinchía Gold Project.

Ceibal lies approximately 1 kilometre south of the Miraflores deposit and 1 kilometre southwest of the Tesorito deposit (Figure 3). The target area is coincident with a sub-circular combined Au-Mo surface geochemical anomaly that has an approximate 800-metre by 600-metre footprint (Figure 1). This surface anomaly defines the exploration area for Tiger’s initial 5,000-metre drill program.

Drilling at Ceibal has intersected a mineralized corridor with an apparent strike length of at least 300 metres and an apparent average width of approximately 300 metres. Mineralization has been traced over a vertical thickness of approximately 600 metres in CEDDH-010 and remains open to depth. The geometry, true thickness, extent, and continuity of mineralization have not been defined, and the corridor remains open to the northwest, southeast, and southwest.

The balance of Tiger’s initial 5,000-metre Ceibal drill program is planned to focus primarily on step-out drilling to test the corridor’s apparent strike extent to the northwest and southeast. Deeper holes are intended to gather data that may identify pathfinders to assist in locating the causative porphyry responsible for the system.

CEDDH-010 Returns 214 m Grading 0.7 g/t Au and 437 m Grading 0.5 g/t Au

CEDDH-010 was drilled as a step-back of CEDDH-001, with the collar set approximately 80 metres northeast of CEDDH-001 along the same section line (Figure 1). The hole was designed to test the long, near-surface gold mineralization intersected in CEDDH-001, CEDDH-005, and CEDDH-009 for depth continuity beneath those holes and for northeast extension along the section line. CEDDH-001, the Ceibal discovery hole drilled by a prior operator, returned 500 metres grading 0.5 g/t Au from surface.

CEDDH-010 was drilled to a final length of 707.7 metres and intersected dacite porphyry over most of its drilled length, with intervals of intrusive breccia and inter-mineral to late diorite porphyry.

From 22 metres downhole, CEDDH-010 returned 214.2 metres grading 0.7 g/t Au, hosted almost entirely in dacite porphyry, and including two higher-grade intervals of 23 metres grading 1.1 g/t Au from 55 metres downhole and 8 metres grading 1.0 g/t Au from 86 metres downhole. The composite is interrupted by a 34.45-metre barren late-diorite dike, as detailed further below and shown in Figure 2.

From 270.65 metres downhole to the end of the hole at 707.7 metres, CEDDH-010 returned a second composite interval of 437.05 metres grading 0.5 g/t Au, including two higher-grade intervals of 9 metres grading 2.2 g/t Au and 114 ppm Mo from 613 metres and 10 metres grading 1.4 g/t Au from 656 metres. The interval is predominantly dacite porphyry with moderate potassic alteration and chlorite-sericite overprinting. Several narrow intrusive breccia intervals were logged throughout and returned grades broadly consistent with the surrounding dacite. The basalt intersected at end of hole (from 695.24 m downhole) was mineralized within the composite at average grades above the 0.2 g/t Au reporting cut-off grade. The hole ended in mineralization and remains open at depth.

CEDDH-010 shows a vertically continuous potassic alteration domain developed in dacite porphyry, with moderate chlorite-sericite alteration overprinting from 140 metres downhole. Sustained chalcopyrite at approximately 0.2 to 0.4%, recurrent traces of bornite and covellite, abundant magnetite (up to 1.5%), and persistent QM-, B-, and M-type vein networks that intensify with depth were observed. These features are consistent with porphyry-style gold mineralization.

With CEDDH-009 and CEDDH-010 now reported, and CEDDH-012 recently completed with assays pending, drilling along this section line (Figure 2) spans the central portion of the Au-Mo surface geochemical anomaly shown in Figure 1.

Drillhole CEDDH-012 is a further step-back of CEDDH-001 collared approximately 150 metres northeast of CEDDH-001 and 70 metres northeast of CEDDH-010. Logging shows broadly comparable proportions of dacite porphyry, inter-mineral to late diorite porphyry, and intrusive breccia. Basalt was also logged near surface and at depth. Assays are pending, and the relationship of these logged units to mineralization has not yet been determined.

As shown in Figure 2, the section is interpreted to include several sub-vertical to steeply dipping dikes that cut the dacite porphyry host rock along the drill line. In CEDDH-010, the central dike, logged as inter-mineral to late-mineral porphyry from 236.2 metres to 270.65 metres downhole, is barren and corresponds with the 34.45-metre interval that separates the hole’s two composite intervals. Farther downhole, the second composite intersects a narrower western dike from approximately 396 metres to 415 metres downhole, associated with intrusive breccia that returned grades consistent with the surrounding dacite porphyry host rock.

The section also includes an interpreted eastern dike logged only in CEDDH-012. As assays for CEDDH-012 are pending, the relationship of the eastern dike to mineralization has not yet been determined.

Overall, logging of drillholes along the section line in Figure 2 shows a dacite porphyry package as the predominant host, cut by sub-vertical to steeply dipping dikes of inter-mineral to late-mineral porphyry and intrusive breccia. Basalt is also logged in several holes with QM- and B-type veining. The interpreted western and central dikes are intersected in multiple holes along the section line, with the eastern dike only encountered in a single hole.

These consistent host-rock and dike relationships are supportive of a broader mineralized porphyry-style system extending between drillholes along the section. Additional drilling along this line and adjacent to it will be used to evaluate the mineralized system’s geometry, true thickness, and continuity. Drilling results to date at Ceibal are being used to inform the detailed planning of a follow-up drill program in support of a maiden Mineral Resource estimate.

Sampling, Quality Assurance and Quality Control

All drilling was completed using HQ- and NQ-diameter diamond core. Drill core is logged by a Company geologist, photographed, cut in half, and sampled at the Company’s core facility in Quinchía, Colombia under the supervision of a geologist. One half of the core is bagged and sent to ALS’ laboratory in Medellín for sample preparation and with sub-samples sent to ALS’ laboratories in Lima, Perú for analysis. The remaining half-core (or quarter-core if a core duplicate sample was taken) is retained onsite as a witness sample. ALS’ Medellín and Lima laboratories are ISO/IEC 17025 accredited and are independent of the Company. All samples are analyzed for gold using 50 g fire assay with AAS finish (Au-AA26). Samples are also analyzed for a 48-element suite by ICP-AES and ICP-MS following a four-acid digestion (ME-MS61L). Where applicable, high-grade and overlimit assays are re-analyzed using an appropriate technique. In addition to the laboratory’s QA/QC practices, certified reference materials, coarse blanks, and quarter-core duplicates are inserted into the sample stream to monitor analytical performance. Other than as reported, no unreported significant core recovery or drilling issues were encountered during the program. Collar coordinates are preliminary and were recorded in the field using handheld GPS with elevation derived from a 2012 airborne LiDAR survey. Drill core was orientated, and downhole orientation surveys were collected at regular intervals.
