TSX-V: NDR

VANCOUVER, Oct. 5, 2018 /PRNewswire/ - New Dimension Resources Ltd. (TSXV: NDR) (the "Company" or "New Dimension") is pleased to report the results of an updated Mineral Resource Estimate ("MRE") for the Las Calandrias Gold-Silver Project in Santa Cruz Province, Argentina. The updated MRE has been prepared by independent mining consultants AGP Mining Consultants Inc. ("AGP Mining") in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). The updated MRE includes contributions from both the Calandria Sur and Calandria Norte deposits (Figures 1&2); a detailed evaluation of the mineral resource potential of the adjacent high-grade Morena vein/breccia system will continue over the coming months.

Highlights

• The updated Mineral Resource Estimate ("MRE") for Las Calandrias has been reported utilizing an optimized constraining shell, and is based on the concept of an open pit for the Calandria Sur deposit and an open pit and possible underground operations for the Calandria Norte Deposit.
  
  
• The updated MRE confirms the robust nature of the Las Calandrias gold-silver resource, and has increased global Indicated Category gold resources contained within constraining pit shells by 22% or 69,000 ounces. Significant potential also still exists for the discovery of new mineral resources at Las Calandrias, especially within the Morena and Despreciada vein/breccia systems, in addition to within new prospects (e.g. Bozal) in the broader Las Calandrias District.
  
  
• The updated MRE for Las Calandrias, as reported by sector:

Calandria Sur Deposit (Figures 3&4) – Mineral Resources within constraining Shell

Calandria Norte Deposit (Figure 5) – Mineral Resources within constraining Shell

Calandria Norte Deposit - Mineral Resources below constraining shell

• The previous MRE for the Las Calandrias Project was reported on an unconstrained basis. On a like-for-like basis (all mineral resources contained within constraining shell), increases in both average gold grade and total contained gold ounces are reported for Calandria Sur (+10% increase in Au grade and +21% increase in contained gold ounces in Indicated Category). At Calandria Norte, the 2018 MRE reports an increase of +13,000 oz in contained ounces (+27%) in Indicated Category.
  
  
• Mineral resources at the Calandria Sur deposit are bounded to the south by the Calandria I claim block boundary.

Eric Roth, New Dimension's CEO, commented today: "I am pleased to be able to report our updated Mineral Resource Estimate for the Las Calandrias Project, which has shown growth even with tighter technical constraints being placed on the outlining of mineral resource areas. And this resource growth occurred without any potential new contributions from the high-grade Morena vein/breccia system, for which we had insufficient time to evaluate in detail. Significant potential still exists at the Las Calandrias Project to expand the known mineralization at Morena (where only the southern end has seen any meaningful drilling), together with the nearby Despreciada-Nido vein system (untested in the 2018 drill program).

With the arrival of the Patagonian summer field season, our geological teams will now accelerate field activities and the process of evaluating and ranking vein targets at both Las Calandrias and elsewhere within our 860 square kilometre portfolio. This field work is expected to lead to the definition of new high-grade gold-silver targets for drill testing during 2019". 

Las Calandrias Mineral Resource Estimate Authorship, Parameters, and Methodology

The updated Mineral Resource Estimate for the Las Calandrias Project was prepared by Mr. Paul Daigle, associate resource geologist with AGP Mining Consultants Inc. and an Independent Qualified Person as defined by Canadian National Instrument NI-43-101 Standards of Disclosure for Mineral Projects. The Mineral Resource Estimate was completed using the following parameters:

• Mineral resources are estimated in accordance with the CIM Mineral Resource definitions referred to in NI 43-101. This mineral resource estimate has an effective date of 14 September, 2018 and was carried out by AGP Mining Consultants Inc. for the Las Calandrias Project, which includes the Las Calandrias Sur and Las Calandrias Norte Deposits.
  
  
• The estimate was completed based on the concept of an open pit for Las Calandrias Sur Deposit; and an open pit and possible underground operations for Las Calandrias Norte Deposit.
  
  
• For the 2009-2012 drill campaigns, the samples were assayed at ALS Laboratories in Mendoza, Argentina. Sample preparation included weighing, drying, crushing of the entire sample to greater than 70% -2mm, taking a split of 250g, and pulverizing the split to greater than 85% passing 75microns (ALS code: PREP-31, DRY-22). Analyses consisted of gold assays and multi-element Inductively Coupled Plasma (ICP) analysis. Gold analyses for all samples were by fire assay (FA) with an atomic absorption (AA) finish (ALS code: Au-AA24). Any results over 10g Au/t were checked using a gravimetric finish (ALS code: Au-GRA22). The 34-element ICP analyses (ALS code: ME ICP41 package) used aqua regia digestion. Silver grades exceeding 100 g Ag/t were checked by FA with a gravimetric finish (ALS code: Ag-GRA21). In 2012, some samples were analyzed for mercury using a cold-vapor AA method (ALS code: Hg-CV41)
  
  
• For the 2018 drill program, the samples were sent to Alex Stewart International S.A. (ASI) in San Julian, Argentina for sample preparation; and to ASI in Mendoza, Argentina for analysis. Sample preparation included weighing, drying, crushing of the entire sample to greater than 80% -2mm, taking a split of 250g, and pulverizing the split to greater than 95% passing 106 microns (ASI code: P-1). Analyses consisted of fire assay for gold and multi-element ICP analysis (ASI code: ICP-AR-39). The 39-element ICP analyses used an aqua regia digest and optical emission spectrometry (ICP-OES) finish. Gold analyses for all samples were by FA with an AA finish (ASI code: Au4-50). Any silver values over detection limit used FA with a gravimetric finish (ASI code: Ag4A-50).
  
  
• AGP validated the assays in the database using the laboratory certificates and spreadsheets from ALS and from Alex Stewart. Approximately 20% of the database was reviewed against the certificates and no issues were encountered.
  
  
• The quality control and quality assurance program for the New Dimension drilling consisted of regular insertion of blanks, duplicates and certified reference materials obtained from Geostat Pty. Ltd., O'Connor (Perth), Australia.
  
  
• The Las Calandrias Sur Deposit was interpolated with 147 diamond drill holes completed by previous operator, Mariana Resources Ltd. ("Mariana") between 2009 and 2012, totalling 23,173 metres. The Las Calandrias Norte Deposit was interpolated with 51 diamond drill holes completed by Mariana and New Dimension between 2009-2012 and 2018, totalling 17,530 metres of drilling; and nine trenches completed by Mariana in 2009.
  
  
• Gold and silver mineralization mainly occurs within a rhyolite dome at the Calandria Sur and, within a breccia zone that cuts a rhyolite dome in Calandria Norte. A country rock wireframe was created surrounding both the Calandria Sur and Norte rhyolite dome wireframes. A higher-grade core at Calandria Sur was developed using an indicator model at a 1.0 gpt Au indicator. Mineralization at Calandria Norte is mainly confined within the breccia zone, striking roughly 055°Az and dipping approximately -60° to the northwest, and varies in true thickness from 2 m to 15 m. This breccia zone was created in Leapfrog and manually adjusted to capture the logged breccia zone. Occurrences of gold mineralization occur sporadically in the hanging wall and footwall of this zone, within the rhyolite dome.
  
  
• Mariana sampled most of the Calandria Sur and Calandria Norte drill core nominally between 0.5 and 2 m intervals. New Dimension sampled the drill core nominally at 1 m intervals. Composite intervals were created at an average composite length of 2.0 m.
  
  
• For the treatment of outliers in the Calandria Sur Deposit, raw assays were capped at 28.60 gpt Au and 12.05 gpt Au; and 602.00 gpt Ag and 208.00 gpt Ag; within the core and dome domains, respectively. In the Calandria Norte Deposit, raw assays were capped at 64.00 gpt Au and 93.60 gpt Ag in the breccia zone domain; and at 9.78 gpt Au and 47.50 gpt Ag in the rhyolite dome and country rock domain.
  
  
• Specific Gravity (SG) in the resource models was derived from a dataset of 451 measurements. The specific gravity measurements were carried out by Mariana using the wet/dry method. For Calandria Sur, 410 SG values were interpolated using inverse distance squared method, from the well-distributed measurements in the deposit. Any block not interpolated were assigned the average SG value of 2.21. For Calandria Norte, the dataset was made up of 41 selected measurements. Due to the low population of density data the block model was assigned the average SG value of 2.41.
  
  
• A (3D) geological and block model was generated using Geovia GEMS™ 6.8.1 software. Calandria Sur block model matrix size of 6 m x 6m x 5 m (width x length x height) and was selected based on the size deemed suitable for an open pit mining scenario. Calandria Norte block model matrix size of 5 m x 3 m x 5 m (width x length x height), rotated 35°counter-clockwise, and was selected based on the size deemed suitable for both an open pit and possible underground mining scenario.
  
  
• Spatial analysis did not produce any decent variograms due to the high variability of the gold and silver grades in both deposits. The grade models were interpolated using inverse distance cubed, and validated using inverse distance squared and nearest neighbour models.
  
  
• The interpolation was carried out in two passes with increasing search ellipsoid dimensions. For both zones, the classification was based nominally on the number composites used to estimate a block and the distance to the nearest composite. Isolated Inferred blocks within core areas of Indicated resource blocks were captured within a wireframe and upgraded to the Indicated Category.
  
  
• In 2012, preliminary metallurgical testwork was completed on material from the oxide, transition and primary zones of the Calandria Sur Deposit. Testwork was carried out by ALS in Sydney, Australia (formerly Metcon Laboratories Pty. Ltd.). The testwork involved a Leachwell^® test to determine how amenable the material was to a leaching process.
  
  
• Under CIM definitions, Mineral Resources should have a reasonable prospect of eventual economic extraction. An optimized constraining shell has been applied to capture reported Mineral Resources. A gold price of US$ 1400/oz Au and US$ 18.50/oz Ag were used for the cut-off calculation which corresponded to three year rolling average seller's price as of September 14, 2018. The cut-off calculation included metallurgical recoveries based on metallurgical testwork to date by oxide zone. In order to assess the Mineral Resources at Calandria Sur, an in situ resource cut-off grade between 0.3 gpt Au and 0.8 gpt Au (varies by oxide zone) has been applied for potential material amendable to open pit extraction. For the Mineral Resources at Calandria Norte, an in situ resource cut-off grade between 0.8 gpt Au has been applied for potential material amendable to open pit extraction and a cut-off grade of 1.5 gpt Au for material below the constraining shell.
  
  
• The quantity and grade of reported Inferred resources in this estimation are conceptual in nature, and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured resource. It is uncertain if further exploration will result in upgrading them to an Indicated or Measured resource category.
  
  
• Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
  
  
• Rounding of tonnes as required by reporting guidelines may result in apparent differences between tonnes, grade, and contained metal content.
