Black Dragon Gold Corp. (ASX: BDG, TSX-V: BDG) ("Black Dragon" or the "Company") is pleased to announce the assay results of three more drill holes from the Company’s 2018 infill and definition drilling campaign at its wholly owned Salave Gold Project in the Asturias region in northern Spain ("Salave" or the "Project").

The results from drill holes BD18-01, 02 and 03 are significant because they have intersected high-grade mineralisation beyond the constraints of the current Mineral Resource model, at depth and down dip to the west and north-west. This confirms the potential for significant exploration upside to Salave’s existing measured and indicated resource of 6.52 million tonnes at 4.51 g/t Au, for 944,000 ounces of gold (see February 2, 2017 News Release).
These new drill results are some of the highest-grade intersections recorded to date at the Project and are expected to have an positive impact on the next Mineral Resource estimate, which is due for completion in late Q3/early Q4 2018.
The main objective of the 2018 drill program was to confirm the extent and continuity of high-grade gold mineralisation at Salave as the Company prepares to immediately undertake a Preliminary Economic Assessment ("PEA") focusing on an updated Mineral Resource estimate and a new underground mine plan.
CEO and Managing Director of Black Dragon, Paul Cronin, commented:
"The drill hole results announced today support our belief that the Salave deposit is open at depth and laterally.
"Additionally, the 2018 drill program has in-filled gaps and voids in the current resource block model and we are anxious to see what impact the rest of the 2018 drilling and possibly a revised interpretation of the deposit will have on an updated Mineral Resource estimate, which we plan to complete once we have received and compiled all results from the remaining two drill holes.
"The new management team at Black Dragon has been working diligently to review the extensive historical work undertaken at Salave, including the establishment of a new Geological Database of the deposit that is substantially more extensive than previously prepared.
"When we listed on the ASX in August, we promised shareholders positive news flow. These results are the start of what we hope will be a period of advancing and improving the value of this tremendous gold project."

The selected intervals included above were based on 2.5 g/t Au cut-off grade, 2 metres minimum interval length and maximum internal waste interval of 2 metres. Reported mineral widths may not represent true width. Collar locations were surveyed in UTM coordinates based on ERTS89 datum, Zone 29N – Please see Appendix 1.
The 2018 drill campaign consists of seven diamond holes (BD18-01-07) totalling 2,117 metres. To date, results have been received for holes BD18-01 to 05. Compilation and verification of results from holes BD18-06 and BD18-07 is pending and expected to be reported in the coming weeks. Hole BD18-05 did not reach its target at depth and was re drilled as Hole BD18-07.
The 2018 drill program targeted the north-west quadrant of the current resource model and was designed to confirm the presence of steep structures associated with high-grade gold mineralisation and to test for possible lateral extensions of flat to shallow west-dipping stacked lenses of mineralisation defined in the Company’s current Mineral Resource model. The Company will be utilising the new information from the 2018 drill holes to update the current Salave Mineral Resource estimate, which will be used as the basis for a PEA and ongoing feasibility study of an underground mine at Salave. Previously released drill results from holes BD18-04 and BD18-05 are summarised below (see 14 April 14 2018 news release for full details):

Reported mineral widths may not represent true width. Collar locations were surveyed in UTM coordinates based on ERTS89 datum, Zone 29N – Please see Appendix 1.
The Salave Deposit consists of a series of stacked horizontal to shallow west-dipping lenses of mineralisation associated with altered (advanced sercitisation and albitisation) fracture zones within the Salave granodiorite. The Salave Granodiorite is a large north-west trending, approximately 500m wide, steeply dipping sill-like intrusive body overlain by metasediments on the western flank of the deposit. The contact between the metasediments and the Salave granodiorite trends approximately north-east and dips gently to the north-west, approximately parallel to the dip of the regional thrust faulting and the Salave Deposit. The mineralised lenses that form the Salave Deposit pinch and swell and at time these lenses appear to coalesce or are connected by steeper structures, which may act as feeders to the mineralisation within the shallow dipping lenses. As the focus moves deeper through the deposit, the lenses appear to offset and step down to the west and collectively form a tabular zone immediately below and roughly parallel to the contact with the overlying metasediments. Not only have drill holes BD18-01 to 05 confirmed and infilled areas of gold mineralisation within the previous resource model, they have intersected high-grade intervals of gold mineralisation outside of the current resource model, at depth and down dip to the west. The 2018 drilling was logged using oriented drill core. This information will be used to complete a detailed structural study in Q4 2018 that will assist in the interpretation of the structural setting that is controlling the distribution of high-grade gold zones amenable to underground mining.

Criteria JORC Code explanation Commentary Sampling techniquesBlack Dragon Gold’s (BDG or "the Company") 2018 drilling programme comprised 7 diamond core drill holes totalling 2,217m of PQ and HQ size drill core. Hole BD18-XX failed to reach its target depth due to issues with drilling fluid, but recovered core was sampled and is to be reported.
The 2018 drilling was initiated with PQ size core to variable depths to approximately the fresh rock interface (16-61m) and then HQ size core in fresh rock till the end of the hole.
Samples consisted of quarter core over predominantly 1 to 2 m lengths (average sample length of 1.33m).
All core was cut along oriented core markings (producing one half and two quarter core lengths) with a diamond saw into various lengths depending on lithology and alteration contacts determined by the drill site geologist. All drill core was sampled and the average sample length for the 2018 drilling was 1.33 m.
Core drilling was used to obtain PQ or HQ size drill core which was subsequently cut lengthwise using a diamond saw to obtain quarter core samples, which were crushed in a jaw crusher before being pulverised in a ring mill to produce a 50 g charge for fire assay and a 25 g charge for near total four acid digest for S, As and Sb analyses. Sample interval breaks were determined by changes in alteration types. There is a strong correlation between gold grades and alteration type and intensity.
Drilling techniquesNo special measures were needed to maximise recovery, with standard drilling practice providing high recoveries.
Also density measures were taken.
Drill core is stored at Black Dragon’s warehouse and logging facility.
The level of detail captured in the logging data is believed to be of an appropriate level to support resource estimation.
For the 2018 drill campaign, all core was cut in half and quartered, and quarter core was assayed.
For the 2018 drill campaign, individual drill core samples were crushed by jaw crusher to 70% <2mm, split sample d using a Boyd rotary splitter, then 1000 gm pulverized to 85% <75um. The Boyd rotary splitter is a demonstrated method of accurately splitting the primary sample and is verified by duplicate analyses of the 2018 drilling. Sample preparation was conducted by ALS Laboratories in Spain.
For the 2018 drill campaign, a second quarter core sample was collected for duplicate analyses and inserted into the sample stream at a rate of one in every thirty samples. All duplicate analyses were reviewed and show acceptable precision and variability.
For the 2018 drill campaign, BDG used ALS Laboratory Group. SL ("ALS") in, Spain and Ireland. ALS, is an ISO 17025-2005 accredited and internationally recognized analytical services provider. ALS utilized the following methods which were deemed to be appropriate for the style of mineralisation:
Sample analyses are considered a partial digestion when using an aqua regia digest and total when using fire assay.
AGQ Laboratories in Seville, Spain was used as an umpire lab for approximately 100 samples, and results have conformed to the initial assay results to an acceptable level of accuracy.
All QA/QC data was reviewed and yielded acceptable levels of precisions and accuracy. No batches failed QA/QC analyses.
Verification of sampling and assaying
Douglas Turnbull, P.Geo. a Qualified Person as defined by National Instrument 43-101, a Competent Person as defined by JORC and consultant to Black Dragon visited the property and core logging facilities in May 2018 and has reviewed and approved of the data reported herein.
CSA Global visited the property in February 2018 and inspected the current drilling and some of the historical collars.
Core is boxed at the drill site and trucked to the company’s core storage facility for logging and storage.
The grid system used is UTM-29, ETRS89 datum.
The data spacing and distribution is sufficient and appropriate for a mineral resource estimate.
The drillers put the core in core-boxes. A Company geologist transported the core to the core logging and storage facility.
At the core logging facility, samples are marked by a project geologist at intervals according to changes in lithology or alteration.
The samples are numbered sequentially including the control samples. The same person always takes the samples with the supervision of the BDG project manager.
There is always oversight of the person controlling the accuracy of the saw cuts.
Each sample is bagged in two bags for transport with bar codes on both sides of the bag and another label inside the bag and closed with a cable tie.
Each hole is sent as one shipment to avoid confusion or mixing of samples from different drillholes.
All core and samples are stored at the core logging and storage facility. The facility is protected by an alarm system and BDG minimizes the number of staff involved with handling the core and having access to the facility.
Audits or reviewsCSA Global has conducted audits of the current sampling techniques and data.
Section 2: Reporting of Exploration Results(Criteria listed in the preceding section also apply to this section)
Criteria JORC Code explanation Commentary Mineral tenement and land tenure statusBDG owns 100% of the Salave gold deposit through its wholly owned Spanish subsidiary Exploraciones Mineras del Cantabrico SL (EMC). The BDG tenure includes five mining concessions and associated extensions covering 662 Ha and an investigation permit covering another 2,765 Ha.
BDG currently has five Mining Concessions and an Investigation Permit detailed in the January 2017 "Amended Technical Report on the Salave Gold Project" by MDA on the Company’s website.
A Mining Concession entitles the holder to develop resources located within the concession area, except those already reserved by the State. An Investigation permit gives the holder the right to carry out, within the indicated perimeter and for a specific term (a maximum of three years), studies and work aimed at demonstrating and defining resources and the right, once defined, to be granted for mining those resources. The term of an Investigation permit may be renewed by the Regional Ministry of Economy and Employment for three years and, exceptionally, for successive periods. The BDG Investigation permit expired in February of 2017 and is currently under application for extension and is pending a response from the respective authority.
The Salave gold deposit and mineral resources as currently defined is situated completely within the confines of the Company’s Mining concessions and is therefore not impacted by a renewal of the Investigation permit.
The Mining Concessions and Investigation permit are subject to restrictions defined by the Plan de Ordenacion del Litoral de Asturias (POLA) which does not allow any surface activity within 500 metres of the coast line of the Bay of Biscay.
The Salave Project is subject to a royalty agreement with SPG Royalties Inc. described in the January 2017 Amended Technical Report on the Salave Gold Project by MDA on the Company’s website.
The Mining Concessions are believed to be in good standing with the governing authority and there is no known impediment to the Concessions remaining in force until expiry dates (2037 to 2045 for the main concessions covering the project).
Exploration done by other partiesExploration activities commenced in 1967 with several periods of exploration and mining studies prior to BDG (originally named Dagilev Capital Corp., renamed Astur Gold Corporation in 2010, renamed Black Dragon Gold Corp. in 2016) taking ownership of the project in 2010. A significant amount of drilling has been undertaken on or immediately adjacent to the current property boundary during this period totalling 484 drill holes for 69,585m completed. The first drilling commenced with Northgate/IMBESA in 1970 and continued with various owners until 2005.
BDG commenced the 2018 drill program in January 2018, the first to be undertaken since 2013.
Geology
Most of the gold mineralisation has been delineated within an area of approximately 500m wide, 780 m long and test to a depth of 420 m. Gold mineralisation occurs in a series of stacked irregular lenses related to faults and fracture zones collectively forming a broad northwest dipping tabular zone parallel to the contact between the Salave granodiorite and overlying metasedimentary rocks. The faults and fracture zones appear to be related to one or more steeply dipping structures, some of which contain high grade gold. These structures may play a role as conduits and opening shallow dipping structures (lenses) for hydrothermal solutions.
Gold mineralisation at Salave is related to hydrothermal alteration of the host granodiorite. The highest grades are associated with intense albite-sericite alteration with fine grained arsenopyrite and stibnite. Destruction of the original textures is a major feature of the most intensively altered and mineralised granodiorite. Quartz veins and quartz carbonate molybdenite bearing veins are present are present in the deposit do not contain gold and represent a separate mineralising event.
Drillhole informationSignificant mineralized intervals from the 2018 drill program were selected based on a 2.5 g/t Au cut off, a minimum interval length of 2m and a maximum allowable, continuous interval of waste of 2m. Assay averages were weighted by individual sample length and no top cutting was applied. Where appropriate, select samples or internal intervals of higher grade gold mineralisation was broken out as an included interval to illustrate how it influenced the overall average of the larger mineralised intervals.
Where encountered included shorter intervals of higher grade results have consistently been broken out as included intervals in the accompanying news release.
There are no metal equivalents reported.
Relationship between mineralisation widths and intercept lengthsReaders are cautioned that information regarding the precise geometry and orientation of the mineralized zones is insufficient in some cases and the reported intervals may not be true widths.
DiagramsCriteria for the selection of mineralised intervals is clearly defined in the accompanying news release and the 2018 drilling was entirely sampled.
All intervals not reported failed to meet the criteria as a result of having little or no gold mineralisation.
Other substantive exploration data
In 2013 Astur Gold engaged a Structural Geological consultant to complete a structural analyses based on observations and measurement of oriented core data from 6 historical drill holes. Details of this work are summarized in the 2017 MDA technical report on the Company’s website.
