Riverside and Questcorp Prepare for Inaugural Drill Program at Union Project in Sonora
Riverside Resources (OTCQB: RVSDF) and Questcorp Mining are preparing for their first-ever drill program at the Union Gold-Silver Project in Sonora, Mexico. The program will include over 1,500 metres of diamond drilling with approximately 7 holes ranging from 150-350m each, targeting three historic mine areas: Union, North Union, and Famosa zones.
The project's historical zones previously produced an estimated 50,000 ounces gold equivalent. Recent exploration work includes Induced Polarization (IP) geophysics surveys and an airborne drone magnetic survey to refine drill targets. Additionally, Riverside announced that Fortuna Mining has terminated its option agreement on the Cecilia Project, with Riverside regaining full control.
The company will be participating in the Rule Symposium 2025 from July 7-11 in Boca Raton, Florida.Riverside Resources (OTCQB: RVSDF) e Questcorp Mining si stanno preparando per il loro primo programma di perforazione presso il progetto Union Gold-Silver a Sonora, Messico. Il programma prevede oltre 1.500 metri di perforazioni diamantate con circa 7 fori di lunghezza compresa tra 150 e 350 metri, focalizzati su tre aree minerarie storiche: Union, North Union e Famosa.
Le zone storiche del progetto hanno precedentemente prodotto un totale stimato di 50.000 once equivalenti in oro. I recenti lavori di esplorazione includono indagini geofisiche con polarizzazione indotta (IP) e un rilievo magnetico aereo con drone per affinare gli obiettivi di perforazione. Inoltre, Riverside ha annunciato che Fortuna Mining ha terminato il proprio accordo di opzione sul progetto Cecilia, con Riverside che ha ripreso il pieno controllo.
La società parteciperà al Rule Symposium 2025 dal 7 all'11 luglio a Boca Raton, Florida.

Riverside Resources (OTCQB: RVSDF)와 Questcorp Mining은 멕시코 소노라에 위치한 Union Gold-Silver 프로젝트에서 첫 번째 시추 프로그램을 준비 중입니다. 이 프로그램은 1,500미터 이상의 다이아몬드 시추를 포함하며, 각각 150~350미터 길이의 7개 정도의 시추공을 통해 Union, North Union, Famosa 세 개의 역사적인 광산 지역을 목표로 합니다.
이 프로젝트의 역사적인 구역들은 이전에 약 50,000온스 금 환산을 생산한 바 있습니다. 최근의 탐사 작업으로는 유도 분극(IP) 지구물리 조사와 드론을 이용한 항공 자기 조사 등이 포함되어 시추 목표를 세밀하게 조정했습니다. 또한 Riverside는 Fortuna Mining이 Cecilia 프로젝트에 대한 옵션 계약을 종료했으며 Riverside가 전적인 통제권을 되찾았다고 발표했습니다.

Vancouver, British Columbia--(Newsfile Corp. - July 7, 2025) - Riverside Resources Inc. (TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY) ("Riverside" or the "Company"), is pleased to provide shareholders with an update on exploration progress at the Union Gold-Silver Project in Sonora, Mexico. The project is under option to Questcorp Mining Inc. ("Questcorp") who recently announced the commencement of their Phase 1 field program (see Questcorp release dated June 24, 2025).
As part of the advancing exploration program, Riverside and Questcorp are lining up for the first-ever drill program at Union, which will follow up on new geophysical and geochemical surveys that have confirmed and refined high-priority mineral exploration Carbonate Replacement Deposit (CRD) targets for gold and base metals. The initial program will comprise over 1,500 metres of diamond drilling with possibly approximately 7 holes ranging from 150-350m per hole designed to test at least three historic mine areas including the Union, North Union, and Famosa zones. Historical records suggest these zones previously produced an estimated 50,000 ounces gold equivalent, primarily from shallow, inclined shafts exploiting mantos and chimney structures of gold-rich CRD-style systems summarized in the published National Instrument 43-101 technical report filed by Questcorp on Sedar+ May 7, 2025.
"With drill targets now defined by first ever ground and airborne detailed geophysics, further supported by surface sampling, the Union Project is now entering an exciting new phase of exploration," said John-Mark Staude, President & CEO of Riverside Resources. "This will be the first-ever drill program on a historically productive but underexplored system at Union and we believe there's real potential for a meaningful discovery. We're pleased to be working with the Questcorp team as both technical collaborators and significant shareholders, with our stake in Questcorp increasing potentially to
Riverside has completed an initial Induced Polarization (IP) geophysics orientation line over the Union Mine, along with a second line over the Union North Mine. These surveys provide valuable conductivity and resistivity data, which can support a more extensive IP program following the upcoming drill campaign. The IP is successfully imaging key resistivity and chargeability features at depth to guide drill collar placement for some of the initial drill holes. The IP profiles correlate with mapped mineralized zones and former workings, helping refine the orientation and location of the planned drill pads. An airborne drone magnetic survey was completed over the property to provide structural context, follow up potential intrusive feeders and give information about pediments and potential faults beneath the post-mineral young cover units.

Ongoing surface geochemistry and mapping continues to strengthen the targeting pipeline, particularly across exposed gold-rich manto zones and along the margins of shallow post-mineral gravel cover. These efforts are focused on delineating the transition zones from covered to exposed mineralization and establishing structural controls that may influence ore continuity at depth.
Mexico Portfolio Update:
Riverside Resources has received formal notice from Fortuna Mining, via its Mexican subsidiary Monumental Minerals, that it has completed Phase 2 exploration work at the Cecilia Project in Sonora, Mexico and will not be proceeding with the option agreement. As a result, Fortuna has not earned any interest in the project. Per the termination terms, Fortuna will cover applicable project-related costs, including taxes and other expenses, for the next six months. Riverside now regains full control of the Cecilia Project and is free to advance the drill-ready targets developed to date or market the opportunity to new potential partners. Over the past year, exploration activities, including drilling, identified gold mineralization in multiple holes and defined several high-priority targets. Most recently, Riverside completed an additional C
Riverside maintains a strong portfolio of partner-funded projects across Mexico and Canada and is pleased to see continued momentum from its partners, including Questcorp, to unlock the potential of quality, earlier-stage assets like Union.
