Lupaka Gold Corp. (TSXV: LPK) (FSE: LQP) is pleased to announce the results from a recent systematic underground sampling program on the newly developed 3430 production sublevel, located 30 metres up-dip of the 3400 Level, at the Company’s 100% owned Invicta Gold Development Project.

Sampling Program Highlights:

• Sample assay values from the Atenea vein on the 3430 sublevel averaged 9.22 grams per tonne (“g/t”) gold equivalent1 (“Au-Eq.”) over a strike length of 130 metres (“m”), with an average sample width of 4.2 m
• Average grade of 9.22 g/t Au-Eq. is higher than the estimated grade of 8.12 g/t Au-Eq. within the block model of the sampled area on the 3430 sublevel and appears consistent with the 9.86 g/t Au-Eq. sampled on the 3400 Level (see news release dated March 15, 2018)
• Geological mapping shows that the hanging wall split has merged with the footwall zone on the 3430 sublevel, which could potentially result in more efficient mining and lower dilution than the assumptions in the PEA
• Development on the 3430 sublevel, including the crosscuts, plus geological mapping and sample assay values demonstrate horizontal widths ranging from 4 m up to 12 m for the Atenea vein on the 3430 sublevel

Development Highlights:

• Approximately 235 m of horizontal development, including 5 cross-cuts, has been completed on the 3430 sublevel, ending in mineralization on the eastern face
• Vent raise from 3400 Level to 3430 sublevel has been completed ventilation circuit established

“Results from the underground sampling program on the newly constructed 3430 sublevel are very encouraging and demonstrates the continuity of the Atenea mineralization both up-dip from the 3400 Level and along strike. Having learned the hanging wall split merges with the footwall zone is an important geological discovery and provides an opportunity to improve on our conceptual mine development costs and dilution assumptions in the PEA. With sampled grades from the 3430 sublevel coming in higher than within our Mineral Resource block model from the same area, we remain well positioned for the commencement of mine production in the third quarter of this year.”

Will Ansley, President and CEO of Lupaka

Development of 3430 Sublevel & Sampling Program Results

Development on the newly constructed 3430 sublevel was initiated in preparation for the first block of mining production (located between the 3400 Level and the 3430 sublevel), scheduled to commence in the third quarter of 2018 (“Q3 2018”). Subsequent to cross-cutting the Atenea vein, lateral development preceded southeast and southwest over approximately 235 m, including the creation of four additional cross-cuts (see plan in Appendix A), ending in mineralization on the eastern face. The 3430 sublevel development also provided an opportunity to demonstrate the vertical and horizontal continuity of the Atenea vein and to compare the sampled grades with the current Mineral Resource block model, as well as the mineralization contained on the 3400 Level, located 30 metres below.

Consistent with the comprehensive sampling program undertaken on the 3400 Level (see plan shown in Appendix B), underground channel sampling was systematically performed on the 3430 sublevel over the width of the development (3.5 m wide by 3.0 metres wide) at intervals of approximately every 5 m (consistent with the size of the Mineral Resource block model), as well as over the five cross-cuts.

The polymetallic mineralization within the Atenea vein is hosted by structurally defined components which were mapped and sampled. Summarized assay sample results are tabulated and presented in Table 1, and a detailed sampling map is provided in Appendix A.

Overall, the sample results were found to be consistent with sample results from the 3400 Level located 30 m below, however, the average sampled grade of 9.22 g/t Au-Eq. is higher than the estimated grade of 8.12 g/t Au-Eq. contained within the Mineral Resource block model from the sampled area. Importantly, the geological mapping on the 3430 sublevel showed that the hanging wall split vein, as seen on the 3400 Level, has merged with the footwall zone. The continuation of the hanging wall split and the footwall zone through the 3430 sublevel was assumed in the Mineral Resource model and in the PEA conceptual mine plan. The merger of these zones could potentially result in more efficient mining and lower dilution upon extraction of the mineralized material (due to the absence of non-mineralized material in between the two zones).

Although the average sampled width of the Atenea vein on the 3430 sublevel was 4.2 m, compared to approximately 6.0 m on the 3400 Level, sampling on the 3430 sublevel was restricted by smaller development headings (3.5 m wide), as well as fewer cross-cuts (5) compared with the 3400 Level (7). Geological mapping and sampling over the 5 cross-cuts on the 3430 sublevel demonstrates an estimated horizontal width of the Atenea vein ranging from 4 m up to 12 m. It is anticipated that the average horizontal width on 3430 sublevel will be in-line, or possibly exceed, the average conceptual mining width of 8.0 m, as estimated in the PEA conceptual mine plan.

Summary results obtained from 205 samples taken in the drift and crosscuts, over spacing of approximately every 5 m, are tabulated in Table 2.

Project Background

Lupaka’s Invicta Gold Project is a polymetallic development project located approximately 120 kilometres north of Lima, Peru. On May 11, 2018 a PEA was completed on the project by SRK Consulting (Canada) Inc. which evaluated the economic potential of the underground extraction of the Indicated and Inferred Mineral Resources from the Atenea Vein close to the existing 3400 Level adit (up to 130 m above the 3400 Level) utilizing a sublevel long-hole, open stoping mining method supported by initial toll treatment processing options. Highlights of the PEA are summarized below:

• Mineral Resource Statement of 3.0 million tonnes of Indicated Mineral Resources at 5.78 g/t Au-Eq. using a 3.0 g/t Au-Eq. cut-off, and 0.6 million tonnes of Inferred Mineral Resources at 5.29 g/t Au-Eq.
• Initial 6-year mine plan (underground) designed on a portion of the Mineral Resource utilizing the existing infrastructure and minimizing capital start-up costs
• Sublevel open stope mining producing ~ 670,000 tonnes of mineralized material at 8.6 g/t Au-Eq.* with production of ~ 185,000 Au-Eq. oz (within initial 6-year mine plan)
• Average annual pre-tax cash flows of US$10.2 million, average annual after-tax cash flow of US$8.2 million
• Annual production of 33,700 Au-Eq. oz, during steady state
• Annual payable metal of 26,700 Au-Eq. oz, during steady state
• All-in Sustaining Costs of US$575 Au-Eq. oz over initial 6-year mine life, average annual pre-tax operating profit of US$12.3 million
• Pre-tax 5% NPV of US$53.6 million
• Low capital investment: US$4.3 million in pre-production capital with a payback of less than one year

The PEA considers only part of the reported Mineral Resource (the Atenea Vein close to existing infrastructure) with the objective of generating positive cash flow from a low-cost operation while simultaneously re-investing in and further evaluating the deposit to potentially expand production in the future.

Quality Control and Assurance

The analyses for this sampling campaign were carried out by ALS, an accredited laboratory, in Lima, Peru, exercising a thorough Quality Assurance and Control program (QA/QC). As part of QA/QC protocol, duplicates, standards and blanks were inserted into the sample processing stream. The sample locations were mapped, surveyed and photographed for reference. Individual sample channels vary between 0.2 to 2.5 metres wide. Samples were bagged, sealed and delivered to the ALS sample preparation facility in Lima, Peru. Gold was assayed by a 50-gram fire assay and re-assayed for the overlimits, with an AAS finish. All ALS labs are ISO 9000 registered.
