Ultra Resources Assays 13.41 Grams Per Ton Gold and 32.15 Grams Per Ton Silver on Head Samples for Metallurgical Testwork From La Rioja Project, Argentina

Ultra Resources Assays 13.41 Grams Per Ton Gold and 32

VANCOUVER, British Columbia, July 21, 2020 (GLOBE NEWSWIRE) — Ultra Resources Inc. (TSX-V: ULT) (“Ultra Resources” or “the Company”) is pleased to announce that it has commenced metallurgical testwork on bulk samples from its Gold Project in La Rioja Province, Argentina. Initial head sample assay work indicates average 13.41 grams per ton (g/t) gold (Au), 32.15 g/t silver (Ag), 0.47 percent (%) copper (Cu), 2.78% lead (Pb), and 0.96% Zinc (Zn).
Highlights (see Tables 1 and 2 below for details)Sample # 101 from Callanas Mines shows 11.43 g/t gold, 25.10 g/t silver.Sample # 102 from El Espinillo Mines shows 15.38 g/t gold, 39.20 g/t silver.Deleterious elements such as arsenic (As) and stibium (Sb) are below the laboratory’s detection limits of 0.01%.Based on multi elemental and copper phase analysis, Au, Ag, Cu, Pb and Zn in bulk samples are recoverable elements although final product range will be determined based on further tests.As announced in the Company’s July 9, 2020 news release, two bulk samples with a total weight of 849 kilograms were collected from Ultra Resources’ Gold Projects in La Rioja Province, Argentina. These samples were shipped to Yantai Xinhai Mining Research & Design Co., Ltd., Shandong, China (“Xinhai”) to carry out metallurgical testwork. The bulk sample # 101 is from Callanas mining licenses and #102 is from El Espinillo mining licenses. To make it a representative sample of mineralization style on the Property, the samples were collected from multiple quartz veins (464 kg) and the historical dump material (385 kg) from each mine.The samples were analysed for multi elements as shown in Table 1 by method DZ/T 0130.2-2006 for sample preparation, and by Atomic Absorption Spectroscopy (AAS) using activated carbon (Method GB/T 20899.13-2017). Xinhai’s laboratories are accredited under “China National Accreditation Service” in accordance with ISO/IES 17025:2017 – General Requirements for the Competence of Testing and Calibration Laboratories (CNAS-CL01 Registration No. L9977). The results presented in the laboratory report are based on three parallel analyses and the weighted average value of the results of gravity concentration tests.Dr. Weiguo Lang, CEO of Ultra Resources, stated that, “The results of head sample show the merits of the La Rioja gold project as a good exploration target with over approximately 63,000 hectares of licensed areas including 13 mining licenses and 3 exploration licenses. We are looking forward to the detailed metallurgical testwork report which will not only include the process flowsheet but also plant design options for various levels of production of already-on-the ground high gold grade dump materials and potential underground mineralization reported in historical exploration information. The shareholders of Ultra Resources will benefit from near-term gold production by leveraging Xinhai’s rich experience in gold processing design and research.”About Yantai Xinhai Mining Group

About La Rioja Gold Project
The gold project in the south of the province of La Rioja Argentina, consists of three prospecting and exploration areas and 13 manifestations of discoveries. Also, in the area there are several historical gold mines and quartz veins in granodiorite rocks hosted by early Paleozoic shearing. Gold mineralization is typically associated with epithermal style shear hosted quartz veins. Initial evaluation of dump material available for historical mines on the Property indicates approximately 25,000-30,000 tons of dump material is available for gold and other metals processing.
