Continental Gold Announces an Updated Mineral Resource Estimate for the Buritica Project, Colombia



TORONTO, ONTARIO--(Marketwired - June 24, 2015) - Continental Gold Inc. (TSX:CNL)(OTCQX:CGOOF) ("Continental" or the "Company") is pleased to announce an updated mineral resource estimate for the Yaragua and Veta Sur vein systems at its 100%-owned Buritica project in Antioquia, Colombia. Undertaken by independent consultants, Mining Associates Limited ("MA"), the mineral resource estimate is based on 271,003 metres of drill core sampling and 7,215 metres of underground sampling (as at May 11, 2015) and was prepared in accordance with National Instrument 43-101 ("NI 43-101").

Highlights
--  Combined mineral resources for the Yaragua and Veta Sur vein systems,
    above a 3 g/t gold cut-off grade, are newly estimated as:

--  The mineral resource estimate represents significant increases in
    Measured and Indicated ("M&I") resources and Inferred resources of gold,
    silver and zinc over those of the previous mineral resource estimate for
    the Buritica project announced by the Company on May 13, 2014 which was
    based on the Buritica database as at December 31, 2013 (the "2014
    Estimate"). The updated mineral resource estimate reflects higher
    estimated tonnages and higher grades. 
--  Gold equivalent mineral resources in the M&I category increased by 60%
    at higher grades (11.4 g/t AuEq) than the 2014 Estimate (11.0 g/t
    AuEq=Au+Ag/50), reflecting the Company's emphasis on infill drilling and
    sampling in 2014 and 2015. Inferred gold equivalent resources grew by
    approximately 9%, also at higher grades (9.0 g/t AuEq) than the 2014
    Estimate (8.2g/t AuEq=Au+Ag/50), reflecting growth in both deposits
    through step-out drilling. The 51% increase in the number of composites
    defining the vein domains increased confidence in mineral resource
    estimations and demonstrate the continuity of the vein domains. 
--  Tonnage-grade estimates were also made of 2-metre wide halos on both
    sides of vein domains. These estimates were utilized to dilute vein
    domains to 1-metre horizontal width and will be very important for
    evaluating potential mining dilution in future economic studies
    undertaken by the Company. 
--  Grade-Tonnage charts (Figure 4) demonstrate the high-grade nature of the
    Yaragua and Veta Sur mineral resources over a range of cut-off grades
    from 0 to 5 g/t gold. 
--  Estimates of tonnage-grade per vertical-metre (Figures 5 and 6) for the
    major vein domains demonstrate significant mineral resources over an
    elevation range of more than 1,000 metres, with less variation than the
    2014 Estimate due to the marked increase in infill drilling. 
--  80% of combined Yaragua and Veta Sur gold resources are situated above
    an elevation of 1,000 metres, including 97% of combined M&I gold
    resources. 
--  Potential remains for future mineral resource increases in the Yaragua
    and Veta Sur vein systems, as most of the vein domains modeled in each
    deposit are open at depth and to the west. The current mineral resource
    estimate also excludes a number of veins to the south and north for
    which there was limited drilling as of the database cut-off date. 

"This current mineral resource estimate significantly surpassed our internal growth expectations for both Measured and Indicated plus total ounces for these categories, and is a testament to the scale of the deposits at Buritica as well as our team's ability to find and delineate ounces at less than $15 per ounce," commented Ari Sussman, CEO. "With 4.71 million Measured and Indicated gold equivalent ounces, the Company plans to forgo the scheduled updated Preliminary Economic Assessment in H2 2015 and will instead initiate a Feasibility Study, the details of which will be released shortly once the relevant contractors are engaged and scheduling has been finalized."

Dr. Vic Wall, Special Advisor to Continental, oversaw the mineral resource modeling and noted: "The Mining Associates mineral resource model for the Yaragua and Veta Sur vein systems is the best done to date for the Buritica project, yet remains well-constrained geologically and conservative in its estimations. The Company is hopeful that the gold and silver resources in both systems continue to grow from future infill and step-out drilling, and that mineral resource confidence levels increase with further underground drilling. Exploration of other largely untested targets to date may contribute to realizing additional precious metal potential of Continental's flagship Buritica project."

Details

Continental's 100%-owned, 59,283-hectare project, Buritica, contains several known areas of high-grade gold and silver mineralization, of base metal carbonate-style ("Stage I") variably overprinted by texturally and chemically distinctive high-grade ("Stage II") mineralization. The two most extensively explored of these areas (the Yaragua and Veta Sur systems) are central to this land package. The Yaragua system has been drill-outlined along 1,100 metres of strike and 1,700 vertical metres and partially sampled in underground developments. The Veta Sur system has been drill-outlined along 1,000+ metres of strike and 1,800 vertical metres and has been partially sampled in underground developments. Both systems are characterized by multiple, steeply-dipping veins and broader, more disseminated mineralization and both remain open at depth and along strike, at high grades. This press release outlines updated mineral resource estimates for the Yaragua and Veta Sur systems, superseding the 2014 Estimate.

MA was commissioned to undertake mineral resource estimations for Yaragua and Veta Sur. Andrew J. Vigar (B.Sc., FAusIMM, MAIG, MSEG and MA Director) has been responsible for estimations, which will be detailed in a Technical Report prepared in accordance with NI 43-101 to be filed on SEDAR within 45 days of this press release. There was close collaboration between MA and the Buritica site geologists and consultants undertaken during site visits and at MA's Brisbane offices, in particular on the selection and tagging of the vein domains in the context of available underground and surface geology.

Resource modeling was based on Continental's Buritica database as at May 11, 2015 and audited by Resource and Exploration Mapping Ltd. Database statistics are summarized below:

In view of their geology, grade distributions and potential mining methods, Yaragua and Veta Sur were modeled as sets of sub-parallel, steeply-dipping vein domains (Figure 1) interpreted from geological mapping and sampling of underground developments and drilling in the upper part of the system and extended to greater depth and along strike from drill intercepts.

The mineral resource estimate is constrained by domains consisting of 3D geological models. The drill-hole data (and underground channel samples where available) were displayed in section and elevation slices showing assays and geology. Intercepts were selected and coded for each vein domain based on the following selection criteria, in decreasing hierarchy:
a.  Gold grades generally greater than 2 g/t Au and/or 100 g/t Ag; 
b.  No assays received, but a "vein" lithology code in the expected
    location; or 
c.  Sub-grade areas where the interpreted vein domain passed through the
    drill-hole but was not already coded (i.e. "brought through"). 

Vein domains were modeled by MA running on the industry leading software Geovia Surpac. For Veta Sur (38 vein domains) and for Yaragua (51 vein domains), assay intercepts were tagged by vein domain name and numerous iterations of 3D sections, plans and visualizations were done to ensure geometrically-consistent vein domains. Other mineralization is present outside of these domains and was partly included in halos around vein domains.

Informing samples consisted of vein composites within domains and one composite sample across each vein intercept. The estimation grid size was 8 metres in X and Y with vein thicknesses (horizontal widths) and gold, silver and zinc grades estimated in 2D unfolded space using Ordinary Krige ("OK") estimation of their width. The informing sample grades were capped on a vein domain or sub-domain basis as determined by geostatistical analysis. However, where blocks are within 25 metres of a capped value, a hybrid estimate was used - being a combination of the capped and uncapped estimate weighted by a binary indicator. A maximum of eight informing samples are used to estimate a block. Within the tightly-constrained vein domains, high-grade and low-grade sub-domains were outlined, using a 2-metre(i)grams gold boundary with at least three samples within that boundary. Results of the Krige estimation were validated against raw data statistics. Trend analysis was made against the informing samples and check estimates done using Inverse Distance Squared (IDS) and Nearest Neighbour (NN) (Polygonal) estimation techniques. The results (Figure 2) are generally in good agreement with the Krige estimates and grade patterns, highlighting the importance of the sub-domaining in minimizing grade "smearing" where data density was low. As expected, IDS estimates slightly higher grades and lower tonnes than OK, whereas NN estimates higher grades and lower tonnes.

The halo zone on each side of the vein for up to 2 metres in distance was also estimated along with the vein in 2D unfolded space. Informing samples were selected separately for the hanging wall and footwall for each vein. Estimation parameters were the same as for that vein. For the dilution to a minimum width of 1 metre, the halo material was selected from the better grade side. The remainder of the halo was unfolded and included in the 3D model to allow for estimation of mining design and dilution.

Results of the 2D estimation for each vein domain were combined to a normal 3D block model with sub-block size of 1 metre (E) by 0.3 metres (N) by 1 metre (RL). The model was then screened for topography and existing workings. The number of informing samples, presence of underground development or mining, clustering of data, distance to nearest informing sample and Conditional Bias Slope from the OK estimate were used by the Qualified Person to digitize contiguous areas defining mineral resource categories in long-section using the following guidelines:
--  Measured 
    --  A contiguous zone with at least 8 informing vein composites 
    --  Maximum of 8 informing vein composites used for each block estimate 
    --  Distance to the nearest informing sample is generally less than 10
        metres but not more than 15 metres internally 
    --  Conditional Bias Slope is generally greater than 0.8 but not less
        than 0.6 
--  Indicated 
    --  A contiguous zone with at least 4 informing vein composites 
    --  Between 4 and 8 informing vein composites used for each block
        estimate 
    --  Distance to the nearest informing sample is generally less than 25
        metres but not more than 40 metres internally 
    --  Conditional Bias Slope generally greater than 0.5 
--  Inferred 
    --  A contiguous zone with at least 3 informing vein composites 
    --  Generally between 3 and 8 informing vein composites used for each
        block estimate 
    --  Distance to the nearest informing sample is generally less than 100
        metres 
    --  Some minor additional areas with at least one informing sample
        within 150 metres are included at depth where geological continuity
        is good but drilling is sparse. 

Figure 3 shows an example of a vein domain for which mineral resources have been estimated by OK of sub-domains.

To view Figure 3, please visit the following link: http://media3.marketwire.com/docs/cnl0624fig3.pdf.

Areas within a vein domain already taken by development and/or historical mining have been removed and also screened for topography. Volumetric estimates were converted to tonnage estimates utilizing an average specific gravity of 3.1 for veins and 2.84 for halo dilution, based on core measurements and computed from multi-element assay data.

Grade-Tonnage charts for 0 to 5 g/t gold cut-off grades are presented below (Figure 4) by mineral resource category for both the Yaragua and Veta Sur vein systems. These are the capped OK estimates for vein domains, diluted to one-metre minimum horizontal widths.

These results demonstrate the high-grade nature of the Yaragua and Veta Sur vein systems over a broad range of gold cut-off grades. The mineral resource tonnes tabled in Figure 4 are only within the tightly-constrained vein domains and thus do not reflect large quantities of undefined lower-grade (less than 3 g/t Au) material outside the currently-defined vein domains.

The results presented below (Tables 1, 2 and 3) are capped Krige estimates at 3 g/t gold cut-off grade and for one-metre minimum horizontal vein thicknesses. This gold cut-off grade reflects conceptual costs for underground development, mining and treatment.

These mineral resource estimates for the Veta Sur vein system are contained in 38 vein domains with average strike extents of 575 metres and average depths extents of 990 metres (Figure 1) within more extensive vein envelopes, up to 1,140-metre strike length and 1,600-metre vertical extents. As well as significant vein extensions to the southwest and to depth, additional vein domains were outlined to the north of the 2014 mineral resource envelope. Most of the modeled veins are open at depth and along strike to the southwest. Vein domains average 1.1 metres (diluted) horizontal width.

The current mineral resource estimates for Veta Sur represents a significant increase in both tonnage and grades compared to the 2014 Estimate. M&I increased by 65% and M&I grades are higher than the 2014 Estimate (12.6 g/t gold and 13.3 g/t AuEq versus 10.9 g/t gold and 11.6 g/t AuEq=Au+Ag/50), largely reflecting successful infill drilling. The tonnage of Measured resources is slightly higher but the Measured grades and contained ounces are lower in the current estimate relative to the 2014 Estimate, largely due to depletion at very high grades of material mined in Veta Sur development.

Inferred Resources in Veta Sur are up 96% and Inferred grades are higher than the 2014 Estimate (8.9 g/t gold and 9.4 g/t AuEq versus 6.6 g/t gold and 7.1 g/t AuEq=Au+Ag/50), reflecting successful step-out drilling. Even though the Veta Sur vein system has significantly grown in all mineral resource categories, there are areas where sparse drilling did not satisfy the minimum criteria for Inferred Resources, leaving potential upside growth in the future.

Mineral resource growth and the increased proportion of higher confidence (M&I) resources reflect a 73% increase in the number of composites defining the vein domains in Veta Sur, primarily resulting from 2014-2015 drilling.

A chart of tonnage and gold grade (calculated at 50 vertical-metre intervals) versus elevation (1,500-metre range) for the bulk of the Veta Sur mineral resource (above 3 g/t gold cut-off) is presented below (Figure 5). The highest grade resources are currently between elevations of 1,600 to 1,800 metres. Otherwise, the Veta Sur system demonstrates remarkably consistent gold grades over more than 1,000 metres of vertical extent. Tonnages for level slices decrease at higher elevations, due to the intersection of certain veins with the topographic surface and also limited by drilling at shallow depths. Lower tonnages at lower elevations are a reflection of limited deep-drilling conducted to date by the Company. However, gold grades continue to be high (averaging 9 g/t gold) in these areas and may suggest the potential of depth at Veta Sur.

76% of Veta Sur gold resources, including 98% M&I mineral resources, are located above elevation of 1,000-metres, yet there may be scope for increasing the confidence levels of resources at all elevations drilled to date.

These mineral resource estimates for the Yaragua vein system are contained in 51 vein domains containing mineral resources above 3 g/t gold cut-off grade with average strike extents of 470 metres and average depth extents of 910 metres (Figure 1) within more extensive vein envelopes, up to 1,125 metres strike length and 1,540 metre vertical extents. As well as vein extensions, additional vein domains were outlined to the north and south of the 2014 Estimate and additional veins were added in central and eastern Yaragua. Most of the modeled veins are open to depth and along strike to the west. Vein domains average 1.1 metres (diluted) horizontal width.

M&I increased by 57% and M&I grades are comparable with the 2014 Estimate (9.8 g/t gold and 10.3 g/t AuEq versus 10.0 g/t gold and 10.6 g/t AuEq=Au+Ag/50), largely reflecting successful infill drilling. Gold and gold equivalent grades of Measured resources are slightly higher but tonnages were down in this category due largely to current and historical mining depletion in 2015 relative to 2014 estimates.

Although Inferred Resources in Yaragua decreased by 18% versus the 2014 Estimate, the grades are higher (9.1 g/t gold and 9.6 g/t AuEq versus 6.6 g/t gold and 7.1 g/t AuEq=Au+Ag/50). The decline in Inferred resources reflected successful conversion to Indicated resources, largely from infill drilling results. Step-out drilling results were largely responsible for the increased grades of Inferred mineral resources in the current estimate. Although the Yaragua system was extended in 2014-2015, some areas of sparse drilling did not satisfy the criteria for inclusion to Inferred resources, leaving potential growth upside for future drill testing.

Mineral resource growth and the increased proportion of higher confidence (M&I) resources reflect a 44% increase in the number of composites defining the vein domains in Yaragua, primarily resulting from 2014-2015 drilling and channel sampling.

A chart of tonnage and gold grade (calculated at 50-metre vertical intervals) versus elevation (1,500-metre range) for the Yaragua mineral resource (above 3 g/t gold cut-off) is presented below (Figure 6), and illustrates the character of the mineral resources at Yaragua over a 1,000-metre vertical range.

Level slice tonnages decrease above elevations of 1,300 metres due to a lack of shallow drilling and due to various veins intersecting with the topographic surface. Tonnages decreased below elevations of 1,200 metres due to sparser drilling-data, resulting in limited modeling of the vein domains at depth. Gold grades otherwise show limited variation over a 1200-metre elevation range, but are highest at the lowest elevations drilled to date.

83% of Yaragua gold resources, including 97% of M&I resources, are above elevation of 1,000 metres, yet there may be scope for increasing the confidence levels of mineral resources over all elevations drilled to date.

The 2015 mineral resource estimate represents significant increases in M&I resources and Inferred resources of gold, silver and zinc compared to the 2014 Estimate, reflecting higher estimated tonnages and increased grades (Figure 6).

Figure 7 illustrates the substantial growth in Buritica gold resources from 2011 (the first mineral resource estimate) to the current estimate. This growth has been coupled with significant increases in M&I (essentially Indicated) resources and also increased proportions of this higher confidence mineral resource category. Despite the successful conversion of large tonnages of previously Inferred gold resources to the Indicated category, the precious metal grades in the latter category have increased in the 2015 estimate relative to the 2014 Estimate. Inferred gold resources in the updated estimate also exhibit increased grade over the two previous estimates.

To view Figure 7, please visit the following link: http://media3.marketwire.com/docs/cnl0624fig7.pdf.

Gold and gold equivalent resources in the M&I category increased by 60%, at higher grades (11.4 g/t AuEq) than the 2014 Estimate (11.0 g/t AuEq=Au+Ag/50), reflecting the Company's emphasis on infill drilling and sampling in 2014-2015. Measured resources decreased slightly, largely due to current and historical mining depletion. Inferred gold resources grew by approximately 9%, also at higher grades than the 2014 Estimate, reflecting successful step-out drilling. The resulting 51% increase in the number of composites defining the vein domains increased confidence in mineral resource estimations and demonstrate the continuity of the vein domains.

Tonnage-grade estimates were also made of 2-metre wide halos on both sides of vein domains, but are not reported as mineral resources. These estimates were utilized to dilute vein domains to 1-metre horizontal width and will be instrumental in defining potential mining dilution in future economic studies.

Grade-Tonnage charts (Figure 4) demonstrate the high-grade nature of the Yaragua and Veta Sur mineral resources over a range of cut-off grades from 0 to 5 g/t gold.

Estimates of tonnage-grade per vertical-metre for the major vein domains (Figures 5 and 6) demonstrate significant mineral resources over an elevation range of more than 1,000 metres and less variation than the 2014 Estimate.

Precious metal resource growth over the 2011-2015 period has been achieved at all-up exploration costs of less than $15/resource ounce of gold. This figure includes the high proportion of infill drilling in recent years, largely responsible for the increases in higher confidence resources.

80% of the combined Yaragua and Veta Sur gold resources are situated above an elevation of 1,000 metres, including 97% of combined M&I mineral resources.

Potential remains for future mineral resource increases in the Yaragua and Veta Sur vein systems, as most of the vein domains modeled in both Yaragua and Veta Sur are open at depth and to the west. The current mineral resource estimate also excludes a number of vein domains to the south and north for which there was limited drilling as of May 2015.

Differences in Reporting of Resource Estimates

This news release was prepared in accordance with Canadian standards, which differ in some respects from United States standards. In particular, and without limiting the generality of the foregoing, the terms "inferred mineral resources," "indicated mineral resources," "measured mineral resources" and "mineral resources" used or referenced in this press release are Canadian mining terms as defined in accordance with NI 43-101 under the guidelines set out in the CIM Standards on Mineral Resources and Mineral Reserves (the "CIM Standards"). The CIM Standards differ significantly from standards in the United States. While the terms "mineral resource," "measured mineral resources," "indicated mineral resources," and "inferred mineral resources" are recognized and required by Canadian regulations, they are not defined terms under standards in the United States. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian securities laws, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies. Readers are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into reserves. Readers are also cautioned not to assume that all or any part of an inferred mineral resource exists, or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, United States companies are only permitted to report mineralization that does not constitute "reserves" by standards in the United States as in place tonnage and grade without reference to unit measures. Accordingly, information regarding resources contained or referenced in this press release containing descriptions of our mineral deposits may not be comparable to similar information made public by United States companies.
