Gold Bull encounters coarse gold in samples at Sandman, improved laboratory assay analysis underway – higher grades expected

VANCOUVER, British Columbia, June 01, 2021 (GLOBE NEWSWIRE) — Gold Bull Sources Corp. (TSX-V: GBRC) (“Gold Bull” or the “Firm”) is happy to report re-assay outcomes of RC drill samples from the high-grade gold intersections at North Hill and Abel Knoll utilizing the metallic display screen fireplace assay technique (with ICP or gravimetric end as applicable). This variation, brought on by the presence of coarse gold, highlights the necessity for a change within the Firm’s assay protocols to make sure that samples more likely to include coarse gold will return repeatable assay outcomes appropriate for inclusion in a mineral useful resource estimate and, that every one mineralization with gold above the cut-off grade is recognized.

HIGHLIGHTS & UPDATE:

• Intersection in SA-0004 with assays decided by metallic display screen fireplace averages 19.76 g/t Au from 41.1 m to 54.9 m, versus 10.95 g/t Au beforehand reported from typical 30 g fireplace assay
• Substantial variation in gold values between metallic display screen fireplace and standard fireplace assay noticed in different samples from excessive grade zone in SA-0001 raises sturdy chance of under-reporting gold values
• Modifications to pattern preparation and assay technique protocols at the moment being carried out, together with re-assaying to establish zones the place gold grade could also be under-estimated and under-reported

Gold Bull CEO, Cherie Leeden commented:

After observing seen gold in RC chips, and reviewing the repeatability of some subject duplicate samples, it grew to become obvious that the Firm wanted to analyze our laboratory approach. By enhancing the standard of our laboratory approach to swimsuit our coarse gold geology at Sandman, we’ve a chance to incorporate mineralization within the mineral useful resource estimate that may in any other case have be excluded, whereas additionally enhancing the accuracy of information used within the mineral useful resource estimate.
The re-analysis with this totally different lab approach is indicating a major enhance in gold values in most samples which leads me to imagine, a number of the coarse-grained gold might have been getting missed in our unique laboratory approach. Extra re-assaying is at the moment underway to rectify this, and we’ll report the brand new outcomes to the market as we obtain them.

Background

Drilling performed since February 2021 at Sandman has returned a number of high-grade gold intercepts which were reported in earlier press releases. Gap SA-0001 at Abel Knoll intersected high-grade gold mineralization from 143.25 m to 149.35 m down-hole (consult with press launch dated March 21, 2021). The common grade of this interval, primarily based on typical fireplace assay (30 g cost), with ICP-OES and gravimetric end as applicable, was reported as 10.75 g/t Au, utilizing a 5 g/t cut-off.

Excessive grade gold mineralization was additionally drilled at North Hill, together with an interval from 41.1 m to 54.9 m with common grade 10.95 g/t Au, primarily based on typical 30 g fireplace assay and 5 g/t cut-off grade (consult with press launch dated March 29, 2021).

Subsequent evaluation of QAQC knowledge (subject duplicate samples) from a variety of holes and the current remark of seen gold in RC chips drilled at North Hill (consult with press launch dated Could 3, 2021) aroused concern that the traditional fireplace assay analytical approach might not produce repeatable assay outcomes for samples at Sandman, the place coarse gold is ceaselessly current within the mineralization. Subsequently, coarse rejects from preliminary crushing of chosen samples from SA-0001 and SA-0004 have been re-assayed utilizing the metallic display screen fireplace assay technique, with ICP-OES or gravimetric end as applicable. Display fireplace assaying addresses the coarse gold subject by sieving out the coarse fraction and assaying it individually and includes assaying a bigger mass (1 kg) of fabric, with a higher likelihood of being consultant of the drill pattern.

The outcomes of re-assaying the SA-0001 and SA-0004 samples utilizing typical fireplace assay (30 g cost) versus metallic display screen fireplace assay are in contrast in graphical type (Determine 1) and tabulated (Desk 1 and Desk 2) under. Outcomes from some samples are elevated and others decreased. This can be a consequence of the traditional fireplace assay dedication being made on a small pattern randomly chosen from materials the place coarse grains of gold are distributed all through, not essentially uniformly. Efforts to completely homogenize coarse gold all through samples by pulverization aren’t totally efficient. Metallic display screen fireplace assay makes use of a 1 kg pulp that’s extra consultant of the drill pattern.

The interval in SA-0004 from 41.1 m to 54.9 m returned a median grade of 19.76 g/t Au utilizing metallic display screen fireplace assay, versus 10.88 g/t Au utilizing typical fireplace assay with 30 g cost. The substantial enhance in common grade on this interval is especially as a result of pattern taken at 42.7 m to 44.2 m down-hole, the place the metallic display screen fireplace assay returned 116.738 g/t Au.   It isn’t attainable to recalculate the common grade of the 143.25 m to 149.35 m interval in SA-0001 as a result of inadequate coarse reject materials remained from the pattern from 146.3 m to 147.8 m to conduct a metallic display screen fireplace assay. Nevertheless, substantial variation in grade between the 2 assay strategies could be seen within the tabulated outcomes (Desk 1).

In future, Gold Bull will likely be submitting all samples inside geologically recognized mineralized zones that return higher than 0.1 g/t Au in typical 30 g fireplace assay for re-assay utilizing metallic display screen fireplace assay, the place ample pattern materials has been collected.

Subsequent steps:

• Submit coarse reject samples from the current drilling program, together with these just lately reported as containing seen gold (consult with press launch dated Could 3, 2021), for metallic display screen fireplace assay
• Modify pattern preparation and evaluation approach shifting ahead
• Proceed drilling program to check exploration targets and lengthen recognized sources at North Hill, Silica Ridge, SE Pediment and Abel Knoll, commencing first week in June

High quality Assurance – High quality Management

Drilling was accomplished utilizing Reverse Circulation (RC) drilling using double wall drill pipe, interchange hammer and 4¾ inch hammer bits to drill and pattern the rock formation. Samples have been taken over 5 foot intervals (1.52m) and have been collected after separation of the pattern utilizing a rotary splitter located on the base of the cyclone. A small portion of the rock chips for every 5 foot interval was positioned into chip trays for document preserving and geological logging. The samples bagged on the rig have been taken to American Assay Laboratories in Sparks NV by a Firm worker. The Firm inserts high quality management (QC) samples at common intervals within the pattern stream, together with blanks and reference supplies with all pattern shipments to watch laboratory efficiency. The QAQC program is overseen by the Firm’s Certified Individual, Cherie Leeden, Chief Govt Officer.

Samples are submitted to American Assay Laboratories’ analytical facility in Sparks, Nevada for preparation and evaluation. The AAL facility is ISO-17025 accredited by IAS. The place samples are re-submitted for metallic display screen fireplace assay, the coarse reject materials remaining from preliminary crushing is pulverized in order that 85% of fabric passes -150 mesh. Three separate 50 g fireplace assays are accomplished on totally different fractions—one on the +150 mesh and two on the -150 mesh with a ensuing calculated grade accomplished utilizing the weights of the corresponding fractions and fireplace assay outcomes. Evaluation for gold is by 50 g fireplace assay lead assortment with Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) end with a decrease restrict of 0.003 ppm. Samples with gold assays above 10 ppm are re-analyzed utilizing a 50 g fireplace assay fusion with gravimetric end, which has a decrease detection restrict of 0.1029 ppm. A normal fireplace assay with 50 g cost can also be accomplished to be used by the lab to find out the kind of end (ICP or gravimetric) that will likely be required for the display screen fireplace assays.
