Vancouver, British Columbia (September 3, 2019) – PRIZE MINING CORPORATION (“Prize” or the “Company”) (TSXV:PRZ) (OTCQB:PRZFF) (MQSP:GR:FRANKFURT) is pleased to announce assay results from the Phase 2 surface sampling program on its Manto Negro Copper-Silver  Project  in Coahuila  State, Mexico. Mapping and sampling over the past several months has focused on extending the known areas of mineralization and identifying targets for the next phase of diamond drilling over a 20 plus kilometre mineralized horizon on surface. With channel sample grades as high as 3.86 percent copper and 44 grams per tonne silver over 1. 3 metres and chip samples as high as 29.3 percent copper and 958 grams per tonne silver, this work has confirmed the extent and potential of the property. Exploration has also continued to characterize Manto Negro as belonging to the category of ‘red-bed type’ copper deposits, similar in style to the world class deposits of the Central African Copper Belt and the Kupferschiefer in Poland.

“Our sampling continues to demonstrate consistent high copper and silver grades on surface over a multi- kilometre area ” stated Michael McPhie, President and CEO of Prize Mining. “These results are a follow up to our successful Phase 1 diamond drilling program completed earlier this year. Results of the current work have been as expected and continue to confirm the district-scale potential of the Manto Negro Project. The information gathered is to be used to define targets for a pending Phase 2 drilling program.” 

The main focus of sampling in the initial Phase 2 program was on the Apache, San Jose and La Curvas concessions owned by Prize where strong copper mineralization is exposed on surface. Mineralization is hosted in the San Marcos red-bed sandstone close to the contact with the overlying Cupido limestone. A total of 40 samples were submitted for analysis including 26 chip and channel samples collected across the widths of the exposed mineralized beds.

Highlights from this work include:

i.         Apache Concession

The Apache concession is the largest within the Manto Negro project area spanning approximately 16 kilometres on the eastern side of the property. A total of 25 samples were taken from 14 exposed workings and historic artisanal mining areas (Apache 1-14). Highlights include the following channel samples:

  • 3.86% Cu and 44 g/t Ag over 1.3 metres
  • 2.62% Cu and 58 g/t Ag over 1.2 metres
  • 2.31% Cu and 28 g/t AG over 1.8 metres

And chip samples along the Apache trend demonstrated consistent high grade results including:

  • 13.9% Cu and 605 g/t Ag at Apache 1
  • 29.33% Cu and 958 g/t Ag at Apache 6
  • 10.8% Cu and 583 g/t Ag at Apache 8
  • 14% Cu and 518 g/t Ag at Apache 9
  • 7.7% Cu and 190 g/t Ag at Apache 10
  • 15.1% Cu and 759 g/t Ag at Apache 14

ii.       San Jose Concession

7 samples were taken from mineralized beds and workings in this area. The best channel sample returned an assay of 2.3% Cu and 28 g/t Ag over 1.8 metres, with chip samples from old dumps and mine workings over a several hundred metre area returning:

  • 17.1% Cu and 1689 g/t Ag
  • 8.05% Cu and 425 g/t Ag
  • Several over limit samples grading above 30% Cu

iii.     Las Curvas Concession

8 samples were taken from mineralized beds and workings in this area. The best channel sample returned 2.5% Cu and 33 g/t Ag over 2 metres with chip samples at old dumps and mine workings over a several hundred metre area returning:

  • 9.65% Cu and 206 g/t Ag
  • 23% Cu and 710 g/t Ag
  • 19.3% Cu and 633 g/t Ag
  • 18.4% Cu and 574 g/t Ag

All samples are chip channel samples and the composites reported above are weighted averages.

Sampling QA/QC and Analysis

The Company follows a rigorous Quality Assurance/Quality Control program over the chain-of-custody of samples with the insertion of blanks and duplicates into the sample stream submitted to the laboratory for analysis. Sample preparation took place at the SGS facility in Durango, Mexico.

All samples were analyzed utilizing SGS’ 34 element four-acid digestion package (GE-ICP40). Samples with over detection silver were re-run by fire assay (GO_FAG313), with overrun copper reanalyzed using a sodium peroxide fusion (GO_ICP90Q).

Jarrod Brown, P.Geo., of TerraLogic, a Qualified Person under NI 43-101, is the Company’s nominated qualified person responsible for monitoring the supervision and quality control of the programs completed on the Company’s properties. Mr. Brown has approved and verified the scientific and technical information in this news release.
