Sonoro Reports Surface Sampling Exposed Multiple Vein Windows Over 750 Meter Extension to Buena Suerte and El Colorado Zones

Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) ("Sonoro" or the "Company") is pleased to report additional assay results from the ongoing surface sampling program at the Company's Cerro Caliche gold project in Sonora State, Mexico. 275 new samples were assayed, bringing the total for the current sampling program to 1,567 samples over four mineralized corridors as described in the Company's news release dated July 20, 2021.

The new results further confirmed material extensions of up to 750 meters over two southern linear structural corridors at the Buena Suerte and El Colorado zones. The sampling results also revealed oxide gold mineralized "windows" among the two southern structural corridors. The windows were accessed via recently built road cuts and drill site excavations and future sampling will investigate potential continuation and extensions.

Surface rock samples were collected from several well-defined vein and gold mineralized structures by channel sampling perpendicular across measured veins and wall rocks with sample lengths ranging from 0.4 to 2.0 meters. Assay results from 17 samples returned grades between 2.5 and 14.3 grams of gold per tonne ("g/t Au"). The image below illustrates five high-priority window targets for the upcoming drilling program as each demonstrated strong stockwork quartz veining and outlined broad zones of gold and silver mineralization.

Analysis of approximately 284 surface samples collected during the current program from the El Colorado/La Ventana and Buena Suerte/San Quintin corridors confirm the southern extensions of the vein trends with numerous parallel sheeted veins and quartz veinlet stockwork. All samples were given equal weighting.

Sample highlights from the El Colorado/La Ventana Corridor:

  • Window A, approximately 100 meters by 130 meters along strike, with 39 samples averaging 0.36 g/t Au and 0.6 grams of silver ("g/t Ag"), including one sample grading 8.6 g/t Au.
  • Window B, approximately 300 meters by 280 meters along strike, with 39 samples averaging 0.63 g/t Au and 4.8 g/t Ag, including one sample grading 4.9 g/t Au over 1 meter and another sample grading 3.7 g/t Au over 1.2 meters.
  • Window C, approximately 300 meters by 50 meters oriented northeast perpendicular to the northwest-oriented regional vein trends, with 51 samples averaging 0.76 g/t Au and 1.9 g/t Ag.

Sample highlights from the Buena Suerte/San Quintin Corridor:

  • Window D, a teardrop shaped area at the Buena Suerte vein zone extension, covering 350 meters in length by a width ranging from 40-80 meters, with 61 samples averaging 0.65 g/t Au and 18.5 g/t Ag.
  • Window E, approximately 220 meters by 100 meters along strike, with 94 samples averaging 0.28 g/t Au and 1.3 g/t Ag, including one sample grading 2.7 g/t Au.

Outside of the targeted windows, sample assays from a vein considered to be the Hanging Wall of the Cabeza Blanca vein (located between windows B and D), returned 1.2 meters averaging 10.8 g/t Au. This vein is hosted in the rhyolitic intrusive rock and is mostly soil covered. Almost one kilometer to the east of window D, sample assays from a one-meter vein located near the Cuervos vein returned 7.5 g/t Au.

Rock types hosting veining in the southern corridor are mainly a rhyolite sub-volcanic unit and a meta quartzite-shale unit with lesser biotite granodiorite. Alteration is predominantly silicification associated with quartz veinlets and sericite with gold-silver mineralization cutting these rock types.

The remaining samples were collected from more widespread areas to the northeast and east of the southern extensions (outside of the above map area). Samples results from this region are generally encouraging and the eastern La Española corridor is another priority target for the Company. Mapping and sampling are currently underway at La Española to quantify the size of the exposed vein. Four prior drill holes intersected the vein including previously announced scout hole SCR-068 which was drilled in 2019 and which intercepted 6.179 g/t AuEq over 3.05 meters and 1.327 g/t AuEq over 9.14 meters.

Stockpiled vein material at the La Española mine surface is noteworthy for its distinct multiple bands with greenish quartz, while dikes of rhyolitic composition are common within the ridge that hosts the vein, which cuts both the rhyolitic unit and quartzite.

Mel Herdrick, Sonoro's VP of Exploration noted, " With this latest round of mapping-sampling information, new priority drill targets have been identified, increasing management's confidence the next drilling campaign may extend gold mineralization to the south. "

Kenneth MacLeod, Sonoro's President and CEO added, "With the continuing success of the surface sampling program in areas that had not been previously explored, we are confident that mineralization at Cerro Caliche will continue to expand with the reverse circulation drill program scheduled to restart in the fall."

John Darch Sonoro's Chairman commented, " These newly identified oxide gold mineralized windows are essential to our fall drilling campaign to expand mineralization at Cerro Caliche. The presence of strong stockwork quartz veining and broad zones of gold and silver mineralization in all five windows confirm that these will be our high-priority targets. We are particularly encouraged with the number of high-grade samples results as we continue to investigate the potential for near-surface higher-grade mineralization. Confirmation of high-grade mineralization could potentially improve the economics of our proposed open-pit Heap Leach Mining Operation in the initial years of mining."

As previously announced, drilling activities on the concession have been paused since April 2021 to provide the exploration team sufficient time to ensure all data and assistance was available for the completion of a Preliminary Economic Assessment( PEA) anticipated to be completed in the Fall. The Company has engaged Micon International Ltd. to prepare an updated resource estimation for inclusion in the PEA being prepared by D.E.N.M. Engineering Ltd.

Quality Assurance/Quality Control ("QA/QC") Measures and Analytical Procedures
Samples are collected as continuous chip samples by hand into plastic bags, GPS positions and rock descriptions noted, the bags are numbered using Bureau Veritas (BV) bar code number books, then sealed and taken to secure storage in Cucurpe village near the project.

Company personnel transport those bagged samples directly to the BV preparation laboratory in Hermosillo, Sonora. At the preparation laboratory samples are logged into the BV system using bar code labels, opened, then reduced in size through crushing, splitting and pulverization. Thirty grams of each pulverized sample is split apart in that laboratory and undergoes a fire assay for gold content by reducing the fire assay to a concentrated button of material that is dissolved in acids, and from the solution the gold content is determined by atomic absorption. About 200 grams of each sample are sent by BV to their Vancouver, Canada laboratory where samples are individually dissolved in aqua regia for multi-element ICP analysis, including silver. Quality control standards were inserted in the sample lineup by the BV Vancouver, laboratory.

No QA/QC issues were noted with the results received from the laboratory.

Geologic Description
Cerro Caliche is located 45 kilometers east southeast of Magdalena de Kino in the Cucurpe-Sonora Mega-district of Sonora, Mexico. Multiple historic small underground gambusino gold mines were developed in the concession including Cabeza Blanca, Los Cuervos, Japoneses, Las Abejas, Boluditos, El Colorado, Veta de Oro and Espanola. Mineralization types of the Cucurpe-Sonora Mega-district include variants of epithermal low sulfidation veins and related mineralized dikes and associated volcanic domes. Local altered and mineralized felsic dikes cut the mineralized meta-sedimentary rock units and may be associated with mineralization both in the dikes and meta-sedimentary rocks.

Top Stories This Week: Experts Talk Next Move for Gold, Uranium Catalysts Pile Up

The gold price has cooled since making a new all-time high on Monday (December 4), but it remained elevated ahead of the latest US non-farm payroll data and in advance of the US Federal Reserve's meeting next week.

For investors, the key question right now is whether the yellow metal will continue rising or make a retreat. Opinions vary, but I heard recently from two experts who aren't so sure that gold is set to break higher — at least in the near term.

Let's take a look at how David Morgan of the Morgan Report explained it:

Kerry Stevenson: Gold, Uranium, Lithium — What I'm Doing with My Money

Kerry Stevenson, host of Making Money Matter, spoke with the Investing News Network about sentiment among Australian resource companies and investors, as well as what she's doing with her money right now.

She sees gold as a key portfolio component, especially during today's turmoil, and said she has exposure to physical gold and silver in addition to gold equities. "For me it's all about diversification. Because my view is that if you keep printing like drunken sailors, then hard assets are something that you really, strongly need to look at," she said.

However, Stevenson, who also runs the Australian Gold Conference, is following markets like uranium and lithium as they continue to gain traction on the back of the ongoing energy transition.

Top 5 Gold Stocks on the TSX in 2023

Gold and gold companies have had a tumultuous year following insolvency in the banking system and tensions continuing between Russia and Ukraine and violence starting during Q4 in the Middle East.

Simultaneously, economic forces from central banks attempts to control 40-year high inflation levels saw interest rates pushing investors away from the yellow metal.

Despite opposing market elements, the price of gold remained elevated in 2023 and approached record prices in May and November before breaking them in December. The high prices have been a boon for gold mining companies, helping drive profits and fund projects and expansions.

Investor Education: US Debt and Currency Collapse with Expert Don Hansen

Private investor Don Hansen has honed his resource sector investment approach for more than 20 years, and in a conversation with the Investing News Network he shared his research on the US debt-to-GDP ratio.

Looking back to 1945, the ratio was at 111 percent due to major spending on World War II. However, by 1965 it was down to just 43 percent — Hansen noted that this happened on the back of a balanced budget and good economic growth. The ratio remained fairly stable from 1965 to 1985, but rose dramatically from 1985 to 2005.

"The debt grew 9.3 percent between 1985 and 2005, but the GDP only grew 6.1," he noted. "So obviously then the debt-to-GDP ratio was climbing, and in 2005 it was up to 61. So you're going up 50 percent in 20 years." By 2025, Hansen expects the ratio to rise to 150 percent, with debt growing 9.5 percent annually and GDP only increasing by 3 percent.

Falcon Gold Eyes Spring Drilling at Newfoundland Copper, Lithium and Gold Projects

Falcon Gold (TSXV:FG,FWB:3FA,OTCQB:FGLDF) is getting ready to ramp up exploration work at its gold, lithium and copper projects in Newfoundland, with permitting and subsequent drilling on the properties expected by spring 2024, according to CEO Karim Rayani.

“Once we get those permits in and we’re able to execute on our drill plan … we’ve been in a fairly slow period, but once drills start turning, I’m fairly optimistic we’ll be able to generate some high-grade material,” he said.

Falcon Gold’s Newfoundland landholdings are surrounded by significant deposits, which Rayani broke down in the interview. For example, its Golden Brook property hosts the Hope Brook zone, which is less than 10 kilometers from the new high-grade lithium discovery at Benton Resources (TSXV:BEX) and Sokoman Minerals' (TSXV:SIC,OTCQB:SICNF) Golden Hope project.
