32 m @ 1.3 g/t Au and 21 m @ 1.6 g/t Au, at
Dos Quebradas in Initial Drill Program
Vancouver, British Columbia--(Newsfile Corp. - April 21, 2026) -
Tiger Gold Corp.
(TSXV: TIGR) (FSE:
D150) (OTCQB: TGRGF) ("Tiger" or the "Company") is pleased to report assay results from two of three
holes drilled in its initial exploration program at Dos Quebradas. Drilling at Dos Quebradas forms part of
Tiger's broader 20,000-metre drill program at its Quinchía Gold Project in Colombia's prolific Mid-Cauca
gold belt. Three diamond drill rigs are currently active across the project, with assays pending from Dos
Quebradas, Tesorito, and Ceibal.
Highlights:
QDQDH-27 returned
282.45 m @ 0.6 g/t
Au
from 18 m downhole, including:
32 m @ 1.3 g/t Au,
and
21.23 m @ 1.6 g/t Au
.
QDQDH-25 returned multiple gold intervals across a 631.1 m hole.
QDQDH-26 intersected mineralized breccia on same section line as QDQDH-27.
Assays pending for QDQDH-26 and for additional holes at Tesorito and Ceibal.
Dos Quebradas has a historical Inferred Mineral Resource estimate of 459,000 oz Au (20.2 Mt at
0.71 g/t Au) reported under the 2012 JORC Code.
The Dos Quebradas estimate is historical, and a qualified person has not done sufficient work to
classify this estimate as current, and Tiger is not treating it as current. See "Dos Quebradas Historical
Mineral Resource" below.
Robert Vallis, President & CEO, commented, "QDQDH-27 is an encouraging result from our initial drill
program at Dos Quebradas - 282 metres of mineralization grading 0.6 g/t gold, including 1.3 g/t Au over
32 and 1.6 g/t Au over 21 m. While we wait for assays from QDQDH-26, which is on the same section
line as QDQDH-27, we are updating our model and planning the next phase of drilling at Dos Quebradas
with the goal of defining a current Mineral Resource, alongside our ongoing programs at Tesorito and
Ceibal."
The results reported in this release relate to drillholes QDQDH-25 and QDQDH-27, the locations of
which are shown in Figure 1, and are summarized in Tables 1 and 2. All intervals are reported as
downhole lengths and true widths have not been determined. Assays for drillhole QDQDH-26 are
pending.
QDQDH-27 Returns Broad Interval of 282 m @ 0.6 g/t Au and Remains Open to Depth
QDQDH-27 was drilled to 300.45 m and returned
282.45 m grading 0.6 g/t Au
from 18 m downhole
and ended in mineralization, including
1.3 g/t Au
over
32 m
and
1.6 g/t Au over 21.23 m
, as detailed in
Table 1.
As shown in Figure 2, the hole was collared into saprolite and passed through a tuff sequence before
entering an inter-mineral magmatic breccia and diorite complex beginning at approximately 113 m
downhole. The upper higher-grade interval of 32 m grading 1.3 g/t Au from 22 m is hosted within a
strongly oxidized tuff sequence with quartz-magnetite ("QM") type veins and abundant magnetite veins,
while the deeper interval of 21.23 m grading 1.6 g/t Au from 131.17 m coincides with inter-mineral
magmatic breccia and associated late and early diorite intrusions with A and B type veins. Below the
breccia-diorite complex, the hole transitions into early diorite and basalt, and terminated in
mineralization, indicating that the system remains open to depth.
Elevated copper and molybdenum values are present throughout the mineralized interval and increase
within the breccia-diorite complex (Table 1). The higher-grade interval from 131.17 m to 152.4 m
returned 0.14% Cu and 37 ppm Mo alongside 1.6 g/t Au over 21.23 m. The spatial correlation between
gold, copper, molybdenum, and alteration assemblages within the breccia host rock is consistent with
the porphyry Au-Cu-Mo signature and alteration framework described in the Mineralization and
Geological Setting section below.
QDQDH-25 Returns Multiple Gold Intervals Across 631 m
As shown in Figure 3, QDQDH-25 was drilled to 631.1 m and returned several gold intervals distributed
across much of its length, as detailed in Table 1. The strongest interval was 60 m grading 0.3 g/t Au from
28 m, hosted within tuffs and inter-mineral magmatic breccia.
The hole also returned 46 m grading 0.3 g/t Au from 109 m within the broader breccia complex.
Geological logging records a long section of inter-mineral magmatic breccia from approximately 99 m to
303 m, with additional intervals of 20.8 m grading 0.2 g/t Au from 284 m and 20.42 m grading 0.3 g/t Au
from 315 m intersected within and below this zone. In the deeper part of the hole, 52 m grading 0.2 g/t Au
from 388 m was intersected, with late diorite and additional breccia phases encountered at depth.
While individual interval grades in QDQDH-25 are modest, the hole suggests that gold mineralization is
present across a significant vertical and lateral extent within this portion of the Dos Quebradas system.
Copper and molybdenum values are low in the shallow intervals but increase with depth: the 52 m
interval from 388 m to 440 m returned 48 ppm Mo, and 0.2 g/t Au, and a 10 m interval from 366 m
returned 128 ppm Mo and 0.2 g/t Au. This vertical zonation pattern, with copper and molybdenum
strengthening at depth relative to gold, is consistent with zonation observed in porphyry systems.
The wide distribution of gold is associated with QM veinlets in wall rock, including basalts and magmatic
breccia. The extent of this mineralized envelope, even in lower-grade sections, is consistent with a broad
hydrothermal system.
QDQDH-26 Intersected Mineralized Breccia on Same Section as QDQDH-27 — Assays Pending
QDQDH-26 was drilled to 343.1 m on the same section line as QDQDH-27. As shown in Figure 3, the
hole intersected inter-mineral magmatic breccia near surface, followed by basalt with intervals of early
diorite, intra-mineral diorite, and additional breccia phases at depth. Assays are pending and will be
reported in a subsequent news release.
Geological Setting, Mineralization, and Exploration Program Framework
Dos Quebradas is located within the Quinchía Gold district in the prolific Mid-Cauca belt of Colombia,
part of a cluster of deposits exhibiting multiple styles of mineralization including porphyry, epithermal
vein, and hydrothermal breccia (Figure 4). Mineralization is primarily hosted within a porphyry-related
intrusive and breccia complex emplaced at the contact between tuff of the Combia Formation and
basalts of the Cretaceous basement, with surrounding volcanic and volcaniclastic country rocks. Tiger's
and prior operator drilling has defined a mineralized footprint of approximately 400 m by 350 m that
remains open for expansion.
At Dos Quebradas, gold mineralization is primarily hosted within a multi-phase complex of inter-mineral
magmatic breccias and diorite intrusions emplaced along the diorite-basalt contact zone. Gold and
copper are associated mainly with B- and QM-type veinlets and in less proportion with A-type veins.
Sulfide mineralogy includes pyrite, chalcopyrite, bornite, and minor molybdenite, with sulphide content
increasing in later intrusive phases.
Prior to drilling, Tiger undertook a comprehensive geological review of the Dos Quebradas prospect,
including re-logging of drill core, geological mapping, surface rock sampling, and a reassessment of the
surface channel sampling results from 2022.
On November 8, 2022, LCL Resources Limited reported results of
146.6 m grading 1.82 g/t Au
,
including
34 m grading 4.22 g/t Au
and
40 m grading 2.16 g/t Au
. These results are from continuous 2
m channel samples taken within the saprolite profile above the Dos Quebradas mineralized zone as
shown in Figure 3. Shallow auger sampling confirmed the presence of near surface gold mineralization,
supporting the interpretation that mineralization extends below the weathered surface. Channel and
auger samples were collected within deeply weathered saprolite of diorite and intrusive breccia. Near-
surface grades may reflect supergene enrichment processes and are not necessarily representative of
primary mineralization at depth.
Tiger's fieldwork and data review contributed to an updated interpretation of the mineralized system,
including the role of diorite intrusions, and characterized the alteration and veining framework, resulting
in the construction of a new lithological model. Notably, gold mineralization at Dos Quebradas is
associated with B- and QM-type vein systems, with A-type veins present but minor and related to early
intrusive phases. The dominant mineralization host appears to be inter-mineral magmatic breccia, rather
than the diorite intrusions emphasized in prior operator interpretations.
Tiger's drilling intersected porphyry-style gold mineralization hosted within a multi-phase sequence of
magmatic breccias and diorite intrusions. Mineralization strengthens where drillholes intersect zones of
higher vein density, and stronger alteration. Alteration is dominated by earlier potassic zones marked by
biotite and magnetite, locally overprinted by chlorite-sericite assemblages.
Tiger's initial three-hole exploration program was designed to evaluate the geometry and grade
distribution of the mineralized system based upon Tiger's Dos Quebradas geological model. These
results are still being assessed and integrated into the model to inform the next phase of drilling.
Additional drilling is warranted to further evaluate the continuity and extent of mineralization. The updated
interpretation described in this news release differs from the geological model underlying the historical
Inferred Mineral Resource estimate, and this drill program is not intended to verify that estimate.
Dos Quebradas Historical Inferred Mineral Resource
The most recent historical Mineral Resource estimate for the Dos Quebradas deposit was prepared by
Resource Development Associates Inc. with an effective date of February 25, 2020, and reported by
LCL Resources Limited in accordance with the JORC Code (2012). The historical estimate consisted of
an Inferred Mineral Resource of 20.2 Mt at 0.71 g/t Au (for 459,000 oz of gold) using a 0.5 g/t Au cut-off.
The historical estimate was based upon 19 diamond drillholes (8,824 m) drilled on 25 m section
spacing, defining mineralization over an approximate 400 m by 300 m area from surface to a depth of
approximately 550 m.
This estimate is considered historical and has not been verified by Tiger. A qualified person has not
done sufficient work to classify this estimate as current, and Tiger is not treating it as current.
Recommended work programs include assaying of core drilled by prior operators to confirm grades,
database validation and verification to ensure data integrity, and updated geological modelling to align
with current CIM
Definition Standards for Mineral Resources and Mineral Reserves
. Tiger considers
Dos Quebradas an exploration prospect within the Quinchía Gold Project, with potential requiring further
drilling and evaluation.
Mineral Resources and Technical Report
A report titled
Quinchía Gold Project NI 43-101 Technical Report & Preliminary Economic
Assessment, Department of Risaralda, Colombia
(effective September 18, 2025) (the "Technical
Report") was filed on SEDAR+ on December 10, 2025. The Technical Report also supports the
disclosure of Mineral Resource estimates for the Miraflores and Tesorito deposits with an effective date
of July 31, 2025. Mineral Resources that are not Mineral Reserves do not have demonstrated economic
viability.
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, and cut in half at the Company's core facility in Quinchía, Colombia. Core is
sampled at predominantly 2 m nominal intervals within mineralized and prospective zones, with 4 m
nominal intervals used in expected waste zones. 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 or North Vancouver, British Columbia for analysis. The remaining half-core, or quarter-core if a
duplicate sample was taken, is retained onsite as a witness sample. ALS' Medellín, Lima, and North
Vancouver 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. No unreported
significant core recovery or drilling issues were encountered during the program. Collar coordinates
reported in this release are approximate and were recorded in the field using handheld GPS with
elevation derived from a 2012 LiDAR survey. Drill core was orientated, and downhole orientation
surveys were collected at regular intervals. Only results that meet Tiger's QA/QC protocols are reported.
