June 30, 2021 - TheNewswire - Vancouver, British Columbia - Gold Basin Resources Corporation (the "Company" or "Gold Basin") (CNSX:GXX.CN) (OTC:GXXFF) is pleased to announce that it has completed a diamond drilling program at the Cyclopic and Stealth deposits located within its 100%-owned Gold Basin oxide gold project, located in north-western Arizona (the "Gold Basin Project" or the "Project").  The drill holes were planned and drilled to provide fresh core for a metallurgical testwork program to be undertaken by metallurgical consultants Kappes Cassiday & Associates ("KCA"), based in Reno, Nevada.  KCA are a highly experienced company with particular expertise with the metallurgy of heap leach operations.

METALLURGICAL TESTWORK PROGRAM

1. Diamond Drilling 

In April and May 2021, a total of six (6) diamond core holes were drilled at the Gold Basin Project, and the primary purpose of these drill holes was to obtain fresh and representative core samples of the mineralised oxide ore.

Four (4) holes were drilled along a 900m strike length of the mineralised Cyclopic structure zone, with each PQ sized core hole sited approximate to a reverse circulation ("RC") hole that possessed consistent mineralised intercepts through the Cyclopic detachment and the underlying 40m detachment.  This approach was targeted to provide representative samples of both the higher-grade oxide ore (typically encountered along both detachment faults) as well as the low-grade zones that occur around and between these fairly flat lying shears.  The remaining two (2) diamond drill holes were drilled at the Stealth deposit approximately 900m west of the Cyclopic structure.

Logging of the diamond drill core and sample selection for the metallurgical testwork program is currently being undertaken by the Company in conjunction with KCA.  It is expected that sample selection will be completed by July 5, 2021.

1. Gold Recovery Testwork 

The Company has agreed to a Scope of Work with KCA for a testwork program that is designed to determine the head and leach characteristics for gold recovery from the Gold Basin Project oxide ore.  Fine gold is known to exist in the ore matrix and the PQ core samples will be split into two parallel streams:

1. conventional crushing; and 

2. high pressure Grinding Rolls (HPGR) crushing 

The crushed material (consisting of 80% passing 6.3mm from both crushing methods) will then be separately subject to the gold recovery testwork.  This methodology will provide data for a comparative analysis of both crushing methods on the gold recovery: KCA utilises the PILOTWAL unit (0.5m diameter x 0.3m wide) for its HPGR work and a copy of the operational data from the PILOTWAL is submitted to ThyssenKrupp Industrial Solutions for industrial design.

The crushed material will also undergo a series of tests that includes:

• - direct cyanidation - coarse bottle roll test;

  - preliminary agglomeration;

  - compacted permeability tests; and

  - column leach tests.

The initial column leach period will be sixty (60) days with additional time if deemed necessary.  It is expected that the total timeframe for the metallurgical testwork program from commencement to the final report will be approximately 4-6 months.

HISTORICAL METALLURGICAL STUDIES

Metallurgical testing on material from the Gold Basin Project is presently limited to two separate studies carried out by KCA in the 1990s on behalf of previous operators of the Project.  During the period 1995-97 KCA received crushed sample material from both the Stealth and Cyclopic mine areas.  The bottle roll and column test work data on these samples indicate that the Gold Basin Project gold mineralisation is amenable to direct cyanidation and consistently showed increasing extractions with decreasing particle size for the samples tested.  The "as-received" samples tested in 1995 yielded a cumulative gold extraction of 96% for the minus 48 mesh particle size and 74.0% for the minus 1/4in (6.3mm) material.

Unfortunately, neither the type or style of the mineralisation nor the representativeness of the material submitted is reported and consequently limits the usefulness of this historical study data.  Further details on these studies are contained in the Company’s National Instrument 43-101 Standards of Disclosure for Mineral Projects technical report dated February 25, 2021 and dated effective February 5, 2021, titled "National Instrument 43-101 Technical Report: Geology and Exploration at the Gold Basin Project Mohave County, Arizona USA", prepared by Hard Rock Consulting, LLC and available on the Company's SEDAR profile at www.SEDAR.com.

PEAK INVESTOR MARKETING

In addition, the Company is pleased to announce that it has entered into an agreement with Peak Investor Marketing Corp. ("Peak") a full-service marketing and consulting services firm focused on the junior mining sector (the "Peak Agreement").  Peak is an independent arms-length entity and will assist Gold Basin with marketing strategy and planning, corporate communications and public relations, with the goal of increasing market awareness of the Company.  Under the terms of the Peak Agreement, the Company will pay a cash fee to Peak of $12,000 per month for an initial 3-month term, and has granted Peak 300,000 stock options.  The stock options will vest immediately and each be exercisable to purchase one common share in the capital of the Company for a period of 12 months from the date of grant at a price of $0.38 per share.

The stock options are non-transferable and any common shares issued upon the exercise thereof will be subject to a four-month hold period from the date of grant pursuant to the policies of the Canadian Securities Exchange.

QUALITY CONTROL AND QUALITY ASSURANCE

The Company initiated diamond drilling on the Gold Basin Project in April 2021 and drilled six (6) holes, with hole depths ranging from 51 to 91m.  All holes drilled at the Cyclopic deposit were vertical and were PQ in diameter.  Core has been transported to a secure facility in Nevada where it will be logged and split using a diamond core saw.
