NexGold Mining Corp. (TSX-V: NEXG) (OTCQX: NXGCF) is pleased to provide additional results from the most recent diamond drilling at the Goliath Gold Complex where the Company has conducted 21,000 metres of a 25,000-metre drill program. The most recent drilling included 6,355 metres of diamond drilling in 30 holes and was focused on drilling parts of the Goliath Deposit, the Eastern Alteration Corridor prospect and at Goldlund Southwest (Figure 1).

Drilling at the Goliath Deposit was conducted to infill specific shallow zones of mineralization within the Mineral Resource¹ that were considered by the Company to be under-drilled. Drilling at the Goliath Deposit included 1,749 metres in 14 drill holes (TL25697 to TL25710) targeting shallow portions of the planned open pit that included intersections of the C, D and E zones located in the footwall to the Main zone, and provide greater certainty on the location of this mineralization (Figure 1; Table 2). Additionally, the Company conducted additional drilling totalling 993 metres in four drill holes (TL25711 to TL25714) at the EAC prospect which is located approximately 1.0 kilometres northeast along strike from the Goliath Deposit and sits outside, but near, the planned infrastructure for the Goliath Gold Complex. Drilling at both the Goliath Deposit and the EAC prospect intersected gold mineralization, as listed below and further detailed in Table 1.

Selected drill intercepts for drilling at the Goliath Deposit and the EAC prospect are provided in Table 1 and include:

• 1.05 g/t gold over 21.20 metres (from 22.80 to 44.00 metres), including 16.20 g/t gold over 0.70 metres, 5.01 g/t gold over 0.50 metres, and 4.67 g/t gold over 0.50 metres in drill hole TL25710;

• 13.67 g/t gold over 1.75 metres (from 107.25 to 109.00 metres), including 34.20 g/t gold over 0.68 metres in hole TL25698;
• 1.45 g/t gold over 7.67 metres (from 93.36 to 101.03 metres), including 2.75 g/t gold over 0.98 metres, 4.40 g/t gold over 0.87 metres, and 3.00 g/t gold over 1.03 metres in drill hole TL25701;
• 0.53 g/t gold over 8.35 metres (from 20.15 to 28.50 metres) including 1.06 g/t gold over 1.00 metre in drill hole TL25714.

Kevin Bullock, President and CEO of NexGold, commented: “We are pleased to provide the most recent drill results from the Goliath Gold Complex. The infill drilling at the deposit provides a greater level of certainty in shallow areas of the planned open pit. We are also excited by the results from the EAC prospect immediately adjacent to the Goliath Deposit, which has demonstrated that additional gold mineralization may be available for further Mineral Resource expansion immediately adjacent to the planned mine and mill infrastructure. Further drilling at the EAC prospect will be required to determine the extent of gold mineralization and to determine if this area could be included in any future development. While these drill results do not inform the ongoing Feasibility Study, they are helpful in post-feasibility development plans and may provide additional Mineral Resources in the future.”

Goldlund Southwest

The Company conducted an initial diamond drilling campaign over an area 2.0 kilometres along strike from the Goldlund Deposit referred to as Goldlund Southwest (Figure 2). 3,613 metres of diamond drilling in 12 diamond drill holes (GSW-25-01 to 12) tested the area for potential along strike extensions of the granodiorite sills hosting the Goldlund Deposit. Dilling intersected several quartz veins and porphyries with local alteration which contained zones of gold mineralization over short distances including:

• 4.97 g/t gold over 0.80 metres (from 250.13 to 250.76 metres) in drill hole GSW-25-04;

• 0.69 g/t gold over 1.73 metres (from 289.27 to 291.00 metres) including 1.30 g/t gold over 0.73 metres; and 0.21 g/t gold over 7.00 metres (from 337.00 to 344.00 metres) in drill hole GSW-25-12.

QA / QC

The Company has implemented a quality assurance and quality control program to ensure sampling and analysis of all exploration work is conducted in accordance with the CIM Exploration Best Practices Guidelines. The drill core is sawn in half with one-half of the core sample dispatched to Activation Laboratories Ltd. facility located in Dryden, Ontario. The other half of the core is retained for future assay verification and/or metallurgical testing. Other QA/QC procedures include the insertion of blanks and Canadian Reference Standards for every tenth sample in the sample stream. A quarter core duplicate is assayed every 20^th sample. The laboratory has its own QA/QC protocols running standards and blanks with duplicate samples in each batch stream. Additional checks are routinely run on anomalous values including gravimetric analysis and pulp metallic screen fire assays. Gold analysis is conducted by lead collection, fire assay with atomic absorption and/or gravimetric finish on a 50-gram sample. Check assays are conducted at a secondary ISO certified laboratory (in this case AGAT Laboratories located in Mississauga, Ontario) following the completion of a program.
