Preliminary Leach Tests Indicate 92% Gold Recoveries for Calandria Norte and Morena Vein/Breccia Zones

TSX-V: NDR

VANCOUVER, June 18, 2019 /PRNewswire/ - New Dimension Resources Ltd. (TSXV: NDR) (the "Company", or "New Dimension") is pleased to report that 92% gold recoveries have been returned from preliminary bottle roll leach tests performed on two high-grade, composite drill core samples from the Calandria Norte and Morena vein/breccia zones at the Las Calandrias Project (Figures 1 and 2).

The leach tests were performed in Parksville, British Columbia by Blue Coast Research ("Blue Coast"), with the main objectives of i) confirming the high gold recoveries returned from earlier LeachWELL tests performed on Calandria Norte mineralization and ii) providing high-level metallurgical data on the potential compatibility of the high-grade Calandria Norte and Morena gold mineralization with the processing circuits utilized in industry-standard gold-silver leach circuits.

Highlights

• Gold recoveries of 92.2% and 92.7% were obtained from bottle roll leach tests performed on two composite samples from the Calandria Norte and Morena vein/breccia zones, respectively. Silver recoveries of 69.8% and 70.8%, respectively, were also reported.
• Measured head grades for the Calandria Norte and Morena samples were 15.0 g/t Au + 61.6 g/t Ag, and 15.2 g/t Au + 28.2 g/t Ag, respectively. The two test samples were composites of quartered drill core intervals as indicated in Table 1.
• These gold-silver recoveries were returned from 48-hour bottle roll leaches at relatively fine grinds (P₈₀=90-100μm).
• Results from the current test work program are broadly in-line with the preliminary results obtained from previous LeachWELL analyses of Calandria Norte.

Eric Roth, New Dimension's CEO, commented today: "I am very pleased to be reporting excellent gold recoveries from the preliminary leach test work undertaken on composite samples from the Calandria Norte and Morena vein/breccia systems. Our view has always been that the higher-grade Calandria Norte and Morena vein systems should be the Company's primary focus at Las Calandrias, and these results further support our strategy. Calandria Norte was one of the components of our updated Mineral Resources Estimate for Las Calandrias released in October, 2018, contributing approximately 61,000 ounces of gold and 159,000 ounces of silver in Indicated Category Resources (see detail in Appendix 1). In contrast, significant strike extent of the Morena system remains to be drill tested and the potential for resource growth remains high. There is no doubt that future work at Las Calandrias will continue to focus on the high-grade Calandria Norte and Morena vein systems."

Leach Test Methodology

The two composite samples used in the leach test work were prepared from quartered drill core samples from the Calandria Norte and Morena vein/breccia zones (Table 1; Figures 3 and 4). The samples were individually crushed and blended at Blue Coast's Parksville facility prior to grinding to approximately 80% passing 100μm and bottle roll leaching. 48-hour bottle roll tests were completed on 500g charges of composite sample and included solution sampling points at 2, 6, 24, and 48 hours for determination of leach kinetics (Figure 5). Both NaCN concentrations and pH were monitored and maintained during the tests, with the resulting test solutions/residues being assayed for gold and silver (and recoveries calculated).

Consumption of NaCN and CaO were estimated at 2.63 kg/t and 1.72 kg/t, respectively, for Calandria Norte and 2.43 kg/t and 1.47 kg/t, respectively, for composite Morena.

Quality Assurance / Quality Control (QA/QC)

New Dimension applies industry-standard sampling methodologies and techniques. All drill core samples utilized in this leach test work program were collected under the supervision of the Company's geologists and in accordance with best industry practices, with quartered HQ-sized core being utilized in this study. All original core intervals from drilling at Las Calandrias were photographed, logged, cut in half with a core saw, and then sent to Alex Stewart's sample preparation facility in Puerto San Julian. Pulps for initial geochemical assaying were then sent to the Alex Stewart's accredited analytical lab in Mendoza, Argentina. All geochemical assays reported herein have been subjected to quality assurance / quality control programs using a combination of internationally-recognized standards, duplicates, and blanks, as provided by Alex Stewart, Blue Coast, and the Company.
