Gold mineralization in the Dolphin/Cleary area is hosted within a broad structural corridor of gold mineralization that is hosted in Dolphin stock, a multiphase intrusive complex, and metasedimentary rocks comprised of various schists. Drilling and historic shallow underground mining has intersected this gold mineralization that extends from surface to depths of over 1,000 m from the Dolphin stock in the west to the Cleary Hill mine workings in the east, a distance of over 1.5km. Gold mineralization is hosted within high-grade quartz veins and silicified zones that occur within a broader lower-grade envelope of quartz stockwork mineralization.
The primary goal of these programs is to increase the grade and size of the current resource and to define the limits of the mineralized corridor through systematic drilling. Four drill rigs have been operating since mid-February, and approximately 11,000 meters have been completed to date.

The width refers to drill hole intercepts; true width cannot be determined due to the uncertain geometry of mineralization.
A brief description of the results of the some of the holes follows:
GS2147
Collared in the immediate footwall of the Dolphin intrusive and remained predominantly in schist until the end of the hole at 593.4. The hole is located approximately 100 metres south of GSDL2003, and again notably intersected higher-grade mineralization from 377 to 544.7m and averaged 2.49 g/t Au over 167.7m within a broader intercept of 2.02 g/t over 216.4 m from 377 to 593.4m. This intercept again demonstrates higher grade mineralization over broad intervals near the footwall contact of the intrusive.
GS2151
Collared in the immediate footwall of Dolphin intrusive the hole returned a broad zone of 617.8 m grading 0.94 gt Au from near-surface. Of particular significance are several zones of higher-grade mineralization including 48.8 m of 2.49 g/t Au from 57 to 105.8m and 42.7 m grading 3.76 g/t Au from 447.1 to 489.8m.
GS2143
Collared 175 metres south of GS2145 and within the Dolphin intrusive, the hole was primarily within schist for the first 200 metres before intersecting intrusive at 204.4 m and remained in intrusive for the next 200 metres before re-entering the schist until the end of the hole. Notable intercepts include 70.1 m grading 1.23 g/t from 343.5 to 413.5m, an over 50% increase over the existing global resource grade of 0.69 g/t Au.
The following holes were drilled to the north to establish the mineralized boundary and to test depths to the north beyond the previous drilling. Holes GS2116, GS2153, GS2148, and GS2135 were drilled near the surface projection of the Colorado Vein and 100 metres downdip of the historic
Results of these holes all of which are approximately 100 metres below the previous mine workings on Cleary Hill and in combination with previously reported drilling down-dip all indicate that the mineralization is continuing to broaden at depth with increasing cohesive grade. (GS2021 - 270.2 – 437 m 166.8 m at 1.55 g/t, and GS2017 which intersected 98.2m of 3.07 g/t from 300.5 to 398.7 g/t – 11.72 g/t uncut) . These holes were approximately 180 metres downdip of the intercept in GS2135.
GS2153
Intersected 0.95 g/t Au over 16.3 metres which is the downdip projection of the Cleary Vein Swarm, approximately 100 metres below the old workings.
GS2148,
Again, intersects the downdip projection of the Cleary Vein Swarm and returned 25.2 m grading 1.7 g/t Au, approximately 100 metres below the old workings.
GS2116
Collared 125 m to the north of GS2137 and designed to infill and determine the depth extent of the mineralization within Cleary Hill area.. Hole GS2116 successfully intersected the near surface projection of the
GS2137
Drilled in a previously undrilled area, and 110 m to the south of GS2116. Highlights include 0.7m of 11.5 g/t Au from 35.7m to 36.4 m typical of the Cleary Vein system. A more cohesive zone was intersected at 386.2 to 410.6 returning 24.4 m of 1.03 g/t. Further demonstrating the broadening and plunging of the mineralization to the south.

Some statements in this news release contain forward-looking information, including without limitation statements as to planned expenditures and exploration programs. These statements address future events and conditions and, as such, involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the statements. Such factors include without limitation the completion of planned expenditures, the ability to complete exploration programs on schedule and the success of exploration programs. The term "Mineral Resource" used above is defined per NI 43-101. Though Indicated Resources have been estimated for the Project, this PEA includes Inferred Mineral Resources that are too speculative for use in defining Reserves. Standalone economics have not been undertaken for the measured and indicated resources and as such no reserves have been estimated for the Project. Please note that the PEA is preliminary in nature, that it includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would allow them to be categorized as mineral reserves. There is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Without limitation, statements regarding potential mineralization and resources, exploration results, and future plans and objectives of the Company are forward looking statements that involve various risks. Actual results could differ materially from those projected as a result of the following factors, among others: changes in the price of mineral market conditions, risks inherent in mineral exploration, risks associated with development, construction and mining operations, the uncertainty of future profitability and uncertainty of access to additional capital.
