Goldplay Exploration Ltd. (TSXV: GPLY, OTCQB: GLYXF – the “Company” or “Goldplay”) is pleased to announce initial results from sampling of the first of 22 historical core drill holes completed in 2010, on the Company’s San Marcial Project in Mexico. These drill holes were not incorporated in the historical NI 43-101 resource completed in 2008 (“historical resource”) and thus represent an opportunity for resource expansion. The results to date have successfully demonstrated continuity of the silver, lead, zinc and gold mineralization down dip and revealed new geological features, supporting upside opportunity for the discovery of new mineralized zones at San Marcial. The core sampling program has successfully identified a high-grade mineralized zone hosted in hydrothermal breccias close to major geological structures cross cutting a highly altered volcanic sequence. Highlights of results for the sampling of drill hole SM10-22 include:

Goldplay President and CEO Marcio Fonseca commented, “Goldplay’s systematic sampling of 22 existing core drill holes (previously only partially sampled) is aimed at expanding resources and delineating mineralized zones to support a high-grade bulk mineable open pit target at the San Marcial Project. We also expect to complete a detailed 3D geological and silver mineralization model. The core reviewed to date reveals a structurally controlled mineralized system, with silver mineralization associated with significant concentrations of lead, zinc and gold, hosted by hydrothermal breccias and fault zones. There is evidence of more than one mineralized event and epithermal features, which are common in the historic Rosario Mining District. The wide hydrothermal breccias hosting the mineralization are closely associated with faults and suggest a large orebody geometry favorable for low strip ratio open pit exploration targets.
The location of drill holes completed prior to the historical resource and the location of sampled drill hole SM10-22 are illustrated as follows (Figure 1).

Drill hole SM10-22 intercepted a wide mineralized zone comprising hydrothermal breccias and fault zones, 100 meters down dip from the closest historical resource intersection at SM08-10 (Figure 2 – below).
The sampling of SM10-22 consisted of an extensive multi element dataset allowing Goldplay to enhance the understanding of the geological environment further and provide guidance for planned additional drilling and exploration activities in the San Marcial Project.
Results of sampling of SM10-22 have confirmed the continuity of high grade silver mineralization and anomalous values for lead, zinc and gold down dip outside of the historical resource. The high-grade interval from this hole represents the deepest intersection outside of the historical resource to date in the San Marcial Project. As a result of the success of sampling of SM10-22, Goldplay has commenced the sampling of the remaining 21 holes that were not included in the historical resource, and will complete a new detailed 3D model, in anticipation of a new resource estimate in the December quarter, 2018.
In addition to the successful sampling of historical drill core, the Company anticipates approval of new drilling permits for the San Marcial Project in Q3, 2018. Goldplay has also received “Ejido” (community) approvals to carry out its planned exploration activities in the San Marcial Project.
Geological Background San Marcial Project
The geological setting at the San Marcial Project, consists of a volcaniclastic package with intercalations of agglomerates, andesites, tuffs and rhyolites, deposited in an epiclastic environment and locally cut by diorite dykes. The silver mineralization is controlled by northwesterly trending faults dipping to the northeast, where hydrothermal breccias occur along the footwall. The highest silver values are related to these hydrothermal breccias and fault zones. The mineralization is also impacted in a number of locations by regional scale north-northwest trending faults.
The high-grade silver mineralized zones at San Marcial vary from a couple of meters up to tens of meters in width, outcropping at surface, as defined by mapping, trenching and sampling. The hydrothermal breccias indicate intense hydrofracturing, with transport and rounding of fragments, as well as cementing by a clay or silica matrix in multiphase mineralized events. The mineralization is largely oxidized, and geochemical distribution indicates that the metalliferous hydrothermal solutions carried high-grade silver and anomalous lead, zinc and gold. The localized gold values provide opportunities for new exploration discoveries at the San Marcial Project.
San Marcial Project Ongoing Exploration
In addition to the work completed to date reviewing the San Marcial historical resource, the existing large exploration data set (completed by previous operators) and ongoing reinterpretation of all data with 3D modelling, Goldplay is carrying out the following activities:
- Sampling and mapping of outcrops inside the historical resource area for better delineation of open pit targets on surface.
- Sampling and mapping of historical underground workings in the center of the area which provides upside potential for resource expansion.
- Surface exploration including channel sampling and mapping along the 3.5km mineralized trend, outside of the historical resource, to define new drilling targets.
- Upon receipt of drilling permits, initiate a drilling program to continue the expansion of the resource, not only along strike, but also down dip, in the historical resource area, based on continuity of high-grade silver mineralization demonstrated by results from the drill hole SM10-22.
QA/QC Protocols
Thorough QA/QC protocols are followed in all sampling programs and in assays completed by the Company. Goldplay’s management includes routine duplicates, blanks and standard samples in assay lots for all surface and drill hole samples. The samples are submitted directly to the SGS laboratory facilities in Durango, Mexico, for sample preparation and assaying. The assaying at SGS is by Fire Assay with AA finish, for Au (> 10 ppm gravimetric finish), Ag ICP-AES with 4 acid digestion (up to 100 ppm). For Ag results over 100 ppm an ICP-AES 4 acid digestion with detection limit from 100-1000 g/t is completed at SGS laboratories in Vancouver, Canada. For samples with over limits of Zn and Pb (>10,000 ppm), an ICP-AES with Sodium Peroxide Fusion is performed, to improve recovery.

About Goldplay Exploration Ltd.
Goldplay owns a >250 sq. km exploration portfolio in the historical Rosario Mining District, Sinaloa, Mexico. Goldplay’s current exploration focus includes surface exploration and drilling, with a resource update to follow at the advanced-stage San Marcial Project and follow up exploration program at the El Habal Project.
The San Marcial land package consists of 1,250 ha, located south of the La Rastra and Plomosas historical mines and 20 km from the Company’s 100% owned El Habal Project in the Rosario Mining District, Sinaloa, Mexico. San Marcial is an attractive, near-surface high-grade silver, lead, and zinc project for which a historical resource estimate has been previously disclosed. A National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) report is the source of this “historical estimate”.
Historical Estimate | Grade | Contained Metal | |||||
Category | Tonnes | Ag (g/t) | Zn (%) | Pb (%) | Ag M(oz) | Zn M(lbs.) | Pb M(lbs.) |

The historical NI 43-101 resource estimate is based on a cutoff grade of 30 g/t Ag for open pit and 80 g/t Ag for underground resource classification completed by Micon International Ltd. for Silvermex Resources Ltd (“Silvermex”) on November 5, 2008. The historical resource is based on 4,884 meters of drilling in 30 core drill holes completed by Silvermex and previous operators over a strike length of 600 meters and vertical extent of 250 meters. A qualified person has not done sufficient work to verify and to classify the historical estimate as current mineral resources and the Company is not treating the historical estimate as current mineral resources. Further work must be carried out to verify all historic information before a resource estimate is possible, and there can be no assurance that when established, that any such resource would be economically recoverable. The NI 43-101 was filed on SEDAR on November 21, 2008 under the name of Silver Ore Mining Corporation the predecessor of Silvermex. Ag equivalent ounces (AgEq oz) is calculated from gpt data. AgEq g/t = Ag g/t + (Pb grade x ((Pb price per lb./Ag price per oz) x 0.0685714 lbs. per Troy Ounce x 10000 g per %)) +(Zn grade x ((Zn price per lb./Ag price per oz) x 0.0685714 lbs. per Troy Ounce x 10000 g per %)). Ag price per oz (US$16.50), Pb price per lb. (US$0.95) and Zn price per lb. (US$1.15)and 100% Metallurgical recoveries.
San Marcial exhibits significant exploration upside supported by regional exploration programs completed by previous operators who identified 14 exploration targets similar to San Marcial within its 100% Goldplay-owned concessions. Some of these exploration targets consist of old shallow pits, caved shafts and historical underground workings in areas with extensive hydrothermal alteration, hosted by major regional structures
The El Habal Project is a drilling stage project with an ongoing drill program. The oxidized gold mineralized zone outcrops along a series of rolling hills with evidence of historical shallow underground mining along a 6 km long prospective corridor. The El Habal Project is located near the historical gold-silver Rosario Mine which reportedly operated for over 250 years. Goldplay’s team has over 30 years of experience with senior roles in exploration, financing, and development in the mining industry, including over ten years of extensive exploration experience in the Rosario Mining District, leading to previous successful discoveries. A current NI 43-101 report on the El Habal Project is filed on SEDAR.
